Description

  The present invention relates to a hair care device for supplying an acidic mist containing an acidic component to a user's hair.

  Conventionally, this type of hair care device has an acid mist generating unit that generates acidic mist by misting an acidic liquid, and a water mist generating unit that generates water mist by evaporating water. Yes.

  Further, the acidic mist generated and the water mist are mixed, a pH detection unit that detects the pH of the mixed mist, and the acidic mist generation unit according to the pH of the mixed mist detected by the pH detection unit And an acidic mist adjusting means for adjusting the supply amount of the acidic mist generated in the above.

  In the hair care device having the above configuration, the pH of the acidic mist applied to the hair is always set to a pH within a predetermined range, thereby maintaining the pH of the user's hair weakly acidic and increasing the strength of the hair. Therefore, it is possible to make the hair resistant to damage (for example, see Patent Document 1).

JP 2009-136565 A

  However, in the conventional configuration, since the pH of the user's hair cannot be detected, it is difficult to supply an acidic mist containing an optimal amount of acidic components according to the pH of the user's hair. Met.

  Specifically, when the hair is treated with an alkaline agent such as a hair coloring agent or permanent wave agent, the hair pH becomes high, and the cuticle on the hair surface is tightened due to lack of acidic components. In some cases, the function of recombining the ionic bonds inside the hair is lowered, and it is difficult to sufficiently protect the hair.

  On the other hand, in the case of hair having a low pH, the acidic component contained in the hair is excessive, and therefore, moisture in the hair is discharged, and there is a possibility that the hair has a dry feel.

  The present invention solves the above-described conventional problems, and an object thereof is to provide a hair care device capable of supplying an optimal amount of an acidic component according to the pH of a user's hair.

  In order to solve the conventional problems, the hair care device of the present invention includes an acidic mist generating unit that generates an acidic mist containing an acidic component, and an acidic mist generated by the acidic mist generating unit on a user's hair. A control device for controlling the amount of acidic components contained in the acidic mist generated from the acidic mist generating unit and the pH detecting unit for detecting the pH of the hair And the controller controls the amount of acidic component of the acidic mist to be changed according to the pH of the hair detected by the pH detector.

  This makes it possible to supply an optimal amount of acidic components to the hair according to the pH of the user's hair.

  The hair care device of the present invention can strengthen the ionic bond in the hair and tighten the cuticle of the hair, thereby making the hair strong and smooth, and sufficiently protecting the hair.

  The first invention includes an acidic mist generating unit that generates an acidic mist containing an acidic component, and an acidic mist discharge port that discharges the acidic mist generated by the acidic mist generating unit toward a user's hair. In the provided hair care device, the hair detection device has a pH detection unit that detects the pH of the hair, and a control unit that controls the amount of acidic components contained in the acidic mist generated from the acidic mist generation unit, The acidic component amount of the acidic mist is controlled to be changed according to the pH of the hair detected by the pH detector.

  In this way, by supplying an optimal amount of acidic components to the hair according to the pH of the user's hair, the ionic bond in the hair is strengthened and the cuticle of the hair is tightened, thereby making the hair strong and smooth. The texture can be made and the hair can be sufficiently protected.

  In the second invention, in particular, the control unit of the first invention includes an acidic component contained in the acidic mist generated from the acidic mist generating unit as the pH of the hair detected by the pH detecting unit increases. A first control mode for controlling to increase the amount is provided.

  As a result, the pH of the hair increases, that is, as the pH of the hair approaches alkalinity, acidic mist containing more acidic components is supplied to the hair, so that the pH of the user's hair is optimized. By making it weakly acidic, the ionic bond in the hair can be further strengthened and the hair cuticle can be tightened to make the hair stronger and smoother.

In a third aspect of the invention, in particular, when the control unit of the second aspect of the invention increases the amount of acidic component contained in the acidic mist generated from the acidic mist generating unit, the degree of increase in the amount of acidic component is determined. A second control mode for controlling to be larger than the first control mode is provided.

  As a result, even if the detected pH of the hair is the same, the amount of supplied acidic components can be made different, so that the condition of the user's hair, in particular, the hair coloring agent and the permanent wave agent By supplying acidic mist containing different amounts of acidic components to the hair according to the presence or absence of the use of alkaline drugs such as, even if the user's hair condition is different, the ionic bond in the hair is further strengthened. By tightening the hair cuticle, the hair can be made stronger and smoother.

  In particular, the fourth invention includes a distance detection unit that detects a movement distance of the acidic mist discharge port with respect to the hair of the third invention, and the control unit is a predetermined movement distance detected by the distance detection unit. Is controlled to switch to either the first control mode or the second control mode according to the amount of change in the pH of the hair detected by the pH detection unit.

  Accordingly, since the first or second control mode can be automatically switched according to the state of the user's hair, the user feels the trouble of switching the control mode. Without supplying an acidic mist containing an optimal amount of acidic components according to the condition of the user's hair, the ionic bond in the hair is strengthened and the cuticle of the hair is tightened more easily. A strong and smooth texture can be achieved.

  In a fifth aspect of the invention, in particular, when the control unit of the fourth aspect of the invention is such that the pH of the hair detected by the pH detection unit is higher than a first predetermined value and lower than a second predetermined value, Control is performed so as to switch to the second control mode when the amount of change in the pH of the hair detected by the pH detector with respect to the predetermined movement distance detected by the distance detector is equal to or less than a third predetermined value. It is a thing.

  As a result, when the pH of the hair is high, or when the amount of change in the pH of the hair with respect to the predetermined movement distance of the acidic mist outlet for the hair is gradual, the control unit determines that the alkaline agent is used. Then, the degree of increase in the amount of acidic component produced is controlled to be larger.

  As described above, the hair containing the alkaline agent is supplied with an acidic mist containing a large amount of acidic components, strengthening the ionic bond in the hair and tightening the hair cuticle, making the hair stronger and smoother. It can be made into a texture.

  According to a sixth aspect of the invention, in particular, the control unit of the fourth aspect of the invention is characterized in that the amount of change in the pH of the hair detected by the pH detection unit with respect to the predetermined movement distance detected by the distance detection unit is When the hair is higher than a predetermined value and the amount of change in the pH of the hair is equal to or higher than a fourth predetermined value, control is performed so as to switch to the second control mode.

  As a result, when the amount of change in the pH of the hair with respect to the predetermined moving distance of the acidic mist discharge port with respect to the hair is large, the control unit uses the above alkaline chemical in the past and new hair has grown. In order to increase the amount of the acidic component produced and to increase the amount of acidic component generated, control is performed so that acidic mist containing a large amount of acidic component is supplied to hair using the alkaline agent. To do.

According to the above, when there is hair that has been used in the past with the alkaline chemicals and hair that has newly grown, it contains a large amount of acidic components only for hair that has been used with the alkaline chemicals. An acidic mist can be supplied to strengthen the ionic bond in the hair and tighten the hair cuticle to make the hair stronger and smoother.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

  On the side where the first sandwiching portion 2a and the second sandwiching portion 2b are opposed to each other, a first hair sandwiching surface 3a and a second hair sandwiching surface 3b each formed in a flat plate shape are provided. When the first holding part 2a and the second holding part 2b are closed, the user's hair 13 is held between the first hair holding surface 3a and the second hair holding surface 3b. It is comprised so that.

  The first clamping part 2a and the second clamping part 2b are provided with a heater 4a and a heater 4b as heating parts for heating the first hair clamping surface 3a and the second hair clamping surface 3b, respectively. The hair 13 held between the first hair holding surface 3a and the second hair holding surface 3b heated by the heaters 4a and 4b is heated.

  The heaters 4a and 4b are electrically connected to the control unit 5 accommodated in the housing 11, and the control unit 5 supplies the power supplied to the control unit 5 from the power cord 6 to the heaters 4a and 4b. Is configured to do.

  The hair care device 1 is a side portion in the longitudinal direction of the first hair clamping surface 3a and the hair 13 is clamped between the first hair clamping surface 3a and the second hair clamping surface 3b. The pH detection unit 14 for detecting the pH of the hair 13 located on the treatment direction side of the first hair clamping surface 3a is disposed on the side where the hair moves, that is, on the treatment direction side (left side in FIG. 2B). ing.

  As the pH detection unit, it is desirable to use a semiconductor pH sensor such as an ISFET (Ion Sensitive Field Effect Transistor) or a glass electrode type pH sensor.

  The pH detection unit 14 is electrically connected to the control unit 5 and configured to transmit the pH detected by the pH detection unit 14 to the control unit 5.

  Furthermore, the housing 11 is provided with a liquid channel 15 connected to the tank 12 and the tank 12 as a liquid supply unit for storing liquid such as water and a treatment agent, and the liquid stored in the tank 12 is The acid mist generator 9 is supplied via the liquid channel 15.

  The acid mist generating unit 9 is composed of a needle-like discharge electrode and an annular counter electrode, and the discharge electrode is electrically connected to the control unit 5, and the power supplied from the power cord 6 to the control unit 5 Is supplied to the discharge electrode of the acidic mist generating unit 9 by the control unit 5.

  In the first clamping part 2a, on the side in the longitudinal direction of the first hair clamping surface 3a and on the opposite side to the treatment direction (left side in FIG. 2 (b)), the first hair clamping surface 3a An acidic mist discharge port 8 opened toward the hair 13 sandwiched between the second hair clamping surface 3 b is provided, and the acidic mist generated by the acidic mist generating unit 9 is directed toward the hair 13. It is configured to release.

  Moreover, the switch 11 for a user to operate is provided in the housing 11, and when the user operates the switch 10, the control unit 5 controls the heaters 4a, 4b or the acid mist generating unit 9. doing.

  About the hair care apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the user holds the hair care device 1 and turns on the switch 10 (in this case, the first control mode is selected), power is supplied from the commercial power source or the like to the control unit 5 via the power cord 6. The

  Next, the control part 5 supplies electric power to the heaters 4a and 4b, and the heaters 4a and 4b are heated. The heat generated from the heaters 4a and 4b is conducted to the first hair holding surface 3a and the second hair holding surface 3b, and the first hair holding surface 3a and the second hair holding surface 3b are heated.

  At the same time, the control unit 5 supplies electric power to the discharge electrode of the acidic mist generation unit 9 (in this case, a negative voltage is applied) to cause corona discharge between the discharge electrode and the counter electrode.

  At this time, the liquid is supplied from the tank 12 through the liquid flow path 15 to the discharge electrode of the acidic mist generating unit 9, and the supplied liquid is refined by the discharge, so that the mist as a charged fine particle liquid is obtained. Is generated.

Further, by the discharge, that nitrogen in the air is oxidized, the nitrogen oxides such nitric acid as the acidic component (HNO ₃₎ is generated.

  The generated mist is mixed (partially dissolved) with the acidic component, whereby an acidic mist is generated. The generated acidic mist is supplied to the hair 13 after being discharged from the acidic mist discharge port 8.

  On the other hand, when the user closes the first clamping part 2a and the second clamping part 2b and clamps the hair 13 between the first hair clamping surface 3a and the second hair clamping surface 3b, the heated first Heat is applied to the hair 13 from the first hair holding surface 3a and the second hair holding surface 3b, and the hair is heated.

  At the same time, the hair 13 comes into contact with the pH detection unit 14, and the pH detection unit 14 detects the pH of the hair 13 and transmits the detected pH to the control unit 5.

  The control unit 5 controls the acidic component amount of the acidic mist generated from the acidic mist generating unit 9 according to the pH received from the pH detecting unit 14.

  Specifically, as shown in FIG. 4, the control unit 5 has an acidic mist generating unit so that the acidic component amount of the generated acidic mist increases as the pH of the hair 13 detected by the pH detecting unit 14 increases. Control is performed so as to increase the power supplied to the nine discharge electrodes.

Therefore, as the pH of the hair increases, that is, as the hair approaches alkalinity, an acidic mist containing more acidic components is supplied to the hair, and as a result, the pH of the user's hair is weakly acidic. As a result, the ionic bond in the hair can be further strengthened to tighten the cuticle of the hair, and the hair can be made to have a stronger and smoother texture.

  Here, the acidic component supplied to the hair is about 0.001 mg / L to 0.1 mg / L, and preferably about 0.005 mg / L to 0.05 mg / L.

  The amount of the acidic component was obtained by measuring the amount of the acidic component dissolved in a certain amount of liquid at a distance of 3 cm from the acidic mist generator 9 when the acidic mist was generated for 1 second. Indicates the value.

  When the user turns off the switch 10, the power supply from the control unit 5 is stopped, and the operation of the hair care device 1 is completed.

  As described above, in the present embodiment, the control unit 5 controls the acidic component amount of the acidic mist generated from the acidic mist generating unit 9 in accordance with the pH of the user's hair 13, whereby the hair An amount of acidic component suitable for a pH of 13 is supplied.

  The pH of the hair 13 is inherently weakly acidic, and it is said that the pH around 3 to 5.5 is an electrically neutral point (isoelectric point). The hair 13 at this isoelectric point is in a state in which the ionic bonds between the internal amino acids are firmly bound.

  However, the hair 13 is damaged by heat, sun exposure, etc. due to the use of daily shampoo and brushing, a dryer, a hair iron and the like, the internal amino acid balance is lost, and the pH of the hair 13 rises. And an internal ionic bond is cut | disconnected, a strain is lost, the cuticle which is the outer shell of the hair 13 opens, and a touch and appearance deteriorate.

  When an acidic component is given to such hair 13, the pH of the hair 13 falls and the internal ionic bond is recombined by approaching the isoelectric point. Therefore, the tensile strength and bending / torsional rigidity of the fibers of the hair 13 are also improved. In addition, the cuticle is in a tightened state.

  Such hair 13 is hard and resistant to damage, and the unevenness of the surface is alleviated and the frictional resistance is lowered, so that it has a smooth tactile sensation, light irregular reflection is suppressed, and appearance gloss is improved. Moreover, when performing a hair set simultaneously, the set retention property improves and it can prevent the shape loss of a set.

  However, when an excessive acidic component exceeding the acid binding ability is applied to the hair 13, the hair 13 cannot take up the acidic component. An excessive acidic component drains the moisture in the hair 13 and causes the hair 13 to become crunchy and rough. In addition, the bonded ionic bond is cut again, resulting in a decrease in rigidity.

  In the present embodiment, when the pH of the hair 13 is low, the amount of the acidic component applied is reduced, so that the hair 13 is brought close to the isoelectric point without excessive application of the acidic component. It becomes possible to do.

  In the present embodiment, only one control mode (first control mode) is shown. For example, the second control mode has a larger degree of increase in the amount of acidic component than the first control mode. More acidic components may be supplied to the hair 13.

In this case, for example, the switch 10 may be configured to be able to switch between the first control mode and the second control mode, so that the user can arbitrarily select the two control modes.

  Here, in general, a drug such as a hair color or permanent wave has an alkaline pH, and when the drug is used for the hair 13, the pH of the hair 13 is greatly increased and the hair 13 is damaged. .

  Since the hair 13 whose pH has become alkaline as described above can take in more acidic components than usual by increasing the acid-binding ability, it supplies more acidic components to the hair 13. It is desirable.

  Therefore, when the said medicine is used, the user can supply more acidic components to the hair 13 than the first control mode by selecting the second control mode with the switch 10.

  For this reason, even when the state of the user's hair 13 is different due to the use of the drug, the ionic bond in the hair 13 is further strengthened and the cuticle of the hair 13 is tightened to make the hair 13 stronger and smoother. be able to.

  In the present embodiment, the acidic mist generating unit 9 is constituted by a discharge electrode and a counter electrode so as to generate acidic mist by corona discharge. For example, the tank 12 includes a liquid containing an acidic component. The same effect can be obtained by storing acidic mist in the stored liquid using an ultrasonic atomizer (not shown) or the like.

  In the present embodiment, the liquid supply unit is configured by the tank 12 and the liquid flow path 15. However, for example, the liquid supply unit is configured by a Peltier unit having a heat dissipation surface and a heat absorption surface (not shown), and the heat absorption surface is acidic. By connecting the discharge electrode of the mist generating part 9 and cooling the discharge electrode, the same effect can be obtained even if moisture in the air is condensed on the discharge electrode and electrostatic atomization is performed. .

(Embodiment 2)
6 is a schematic perspective view showing the appearance of the hair care device according to Embodiment 2 of the present invention, and FIG. 7 is a schematic view showing the internal configuration of the hair care device. Here, only matters different from the first embodiment will be described, and the description of the first embodiment is used for those having the same configuration, operational effects, and the like.

  The difference of the second embodiment of the present invention from the first embodiment is sandwiched between the first hair clamping surface 3a and the second hair clamping surface 3b in the vicinity of the first hair clamping surface 3a. The movement distance sensor 16 is provided as a distance detection unit that detects the movement distance of the acidic mist discharge port 8 toward the treatment direction with respect to the hair 13.

  As the movement distance sensor 16, it is desirable to use an optical movement distance sensor, a rotary sensor, or the like. It is also possible to calculate by integrating the speed obtained from a thermal speedometer, a gyro sensor or the like. The movement distance sensor 16 is electrically connected to the control unit 5 and is configured to transmit the detected movement distance to the control unit 5.

  About the hair care apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, it is the same as in the first embodiment from when the user holds the hair care device 1 and turns on the switch 10 until the acid mist is released.

The difference between the present embodiment and the first embodiment is that the acidic mist discharge port 8 moves relative to the hair 13 held by the first hair holding surface 3a and the second hair holding surface 3b. The distance is detected, and the first control mode and the second control mode are automatically switched according to the amount of change in pH of the hair 13 when the acidic mist discharge port moves a predetermined distance.

  FIG. 8 is a flow chart of the control of the hair care device of the present embodiment, and FIG. 9 is a characteristic diagram showing the relationship between the pH of the hair 13 and the amount of acidic component generated in the hair care device.

  When the user closes the first clamping part 2a and the second clamping part 2b and clamps the hair 13 to be cared for with the first hair clamping surface 3a and the second hair clamping surface 3b, the pH detection part 14 The hair 13 comes into contact with the hair 13 and the pH detector 14 starts detecting the pH of the hair 13 and transmits the detected pH to the controller 5 (STEP 01).

  When the user moves the hair care device 1 in the treatment direction, the pH detection unit 14 and the acidic mist discharge port are applied to the hair 13 held by the first hair holding surface 3a and the second hair holding surface 3b. 8 moves relatively (STEP02).

  The movement distance sensor 16 detects the movement distance of the acidic mist discharge port 8 and transmits the detected movement distance to the control unit 5. When the acidic mist discharge port 8 moves a predetermined distance, The pH of the hair 13 is detected (STEP 03).

  When the pH is equal to or lower than the first predetermined value, the control unit 5 performs control so as to switch to the first control mode (STEP 04).

  On the other hand, when the pH is greater than the first predetermined value and greater than or equal to the second predetermined value, the control unit 5 performs control so as to switch to the second control mode (STEP 05).

  Next, the control unit 5 determines the pH relative to the predetermined moving distance from the pH before moving the acidic mist discharge port 8 (pH 1 in FIG. 8) and the pH when moving the predetermined distance (pH 2 in FIG. 8). The amount of change (pH 2-1 in FIG. 8) is calculated, and control is performed to switch to the second control mode when the amount of change in pH is equal to or less than the third predetermined value (STEP 06).

  On the other hand, the control unit 5 performs control so as to switch to the second control mode when the amount of change in pH is greater than the third predetermined value and greater than or equal to the fourth predetermined value (STEP07).

  In accordance with the switching of the first control mode or the second control mode, the control unit 5 controls the amount of acidic mist generated in the acidic mist generating unit 9 (STEP08, STEP09).

  The predetermined moving distance is about 0.5 cm to 5 cm, preferably about 1 cm to 2 cm.

  Further, the first predetermined value at pH is about 6 to 7, and the second predetermined value is about 4 to 5.5.

  The third predetermined value in the amount of change in pH is about 0.005 / cm to 0.025 / cm, and preferably about 0.01 / cm to 0.02 / cm. Further, the fourth predetermined value is about 0.05 / cm to 1 / cm, and preferably about 0.1 / cm to 0.2 / cm.

  Thus, in the present embodiment, the control unit 5 performs the first control mode and the second control mode according to the amount of change in the pH of the hair 13 when the acidic mist discharge port 8 moves a predetermined distance. By automatically switching the control mode and controlling the amount of acidic mist generated in the acidic mist generating unit 9, acidic mist containing an acidic component in an amount corresponding to the state of the hair 13 is supplied to the hair 13. .

  Here, since the properties of the hair 13 differ depending on whether or not the drug is used, the optimum amount of acidic components varies. However, it is extremely complicated for the user to determine the state of the hair 13 himself and switch between the first control mode and the second control mode.

  In addition, when the medicine unused hair and the medicine used hair are mixed (for example, when the new hair 13 grows with the passage of time after using the medicine), the state of the user's hair 13 is judged. May become difficult.

  According to the present embodiment, it is possible to determine whether or not a medicine is used from the amount of change in pH with respect to a predetermined movement distance of the hair 13, and to automatically switch to an optimal control mode according to the state of the hair 13.

  Moreover, in the hair 13 which is not using the said chemical | medical agent, there exists a tendency for pH of the hair 13 to rise, so that it leaves | separates from a scalp by daily damages, such as a heat | fever and sunlight.

  In the healthy hair 13 having no daily damage, the pH of the hair 13 is not increased and the first predetermined value is not exceeded. For this reason, when the detected pH is equal to or lower than the first predetermined value, it can be determined that the hair 13 is not using the medicine, so control is performed so as to switch to the first control mode. ing.

On the other hand, in the hair 13 using the drug, hydroxide ions (OH ⁻ ) penetrate into the hair 13 and remain due to contact with the alkaline drug.

  For this reason, the entire hair 13 becomes alkaline, and the amount of change between the pH of the scalp-side hair 13 and the pH of the hair-end-side hair 13 becomes gentle. Therefore, when the pH of the hair 13 is higher than the second predetermined value, and when the amount of change in the pH of the hair 13 with respect to the predetermined moving distance is equal to or less than the third predetermined value, the drug is used. Since the hair 13 can be determined, the control is performed so as to switch to the second control mode.

  In addition, when time elapses after the drug is used and new hair 13 is stretched, the pH of the hair 13 remains low on the scalp side, but the pH rapidly increases from the part where the drug is used. . That is, when the amount of change in the pH of the hair 13 with respect to the predetermined movement distance is larger than the fourth predetermined value, it can be determined that the hair 13 uses the medicine after that portion. Control is performed to switch to the control mode.

  As described above, in the present embodiment, the user closes the first clamping part 2a and the second clamping part 2b, and the first hair clamping surface 3a and the second hair clamping surface 3b By simply pinching the hair 13 to be cared for and moving the hair care device 1 in the treatment direction, the controller 5 determines whether the hair 13 is used from the pH of the pinched hair 13 and the amount of change in the pH. The use history can be determined and the mode can be automatically switched to the control mode corresponding to the state of the hair 13.

  By the above, an acidic component in an amount suitable for the condition of the hair 13 is automatically determined and supplied to the hair 13, thereby strengthening the ionic bond in the hair 13 and tightening the cuticle of the hair 13. A stronger and smoother texture can be achieved.

  As a modification of the above embodiment, the hair care device 1 is a hair that holds the hair 13 between the first hair holding surface 3a and the second hair holding surface 3b and heats the hair 13 with the heaters 4a and 4b. Although the iron is used, as shown in FIG. 10, it may be a hairbrush having a bristle 17 that rectifies the hair 13 on one side of the housing 11 and imparting acid mist to the hair 13 that passes between the bristle 17.

  At this time, the pH detection unit 14, the movement distance sensor 16, and the acidic mist discharge port 8 are arranged on the surface of the housing 11 on which the bristle 17 is provided.

  With the above configuration, the user can hold the hair 11 on the housing 11 of the hair care device 1, pass the hair 13 between the bristle, and move the hair 13 in the treatment direction. Can be discharged from the acidic mist discharge port 8 and the acidic mist can be supplied to the hair 13 so that the hair 13 approaches the isoelectric point.

  In addition to the above modification, as shown in FIG. 11, the air flow path 21 connecting the air suction port 22 and the air discharge port 23, the fan 18 provided in the air flow path 21, and the fan 18 are rotated. The hair dryer having the motor 19 and the air heating heater 20 for heating the air flowing through the air flow path 21 may be used.

  The motor 19 and the fan 18 are connected by the same rotating shaft (not shown), and the motor 19 and the air heating heater 20 are electrically connected via the control unit 5 and supplied from the control unit 5. Driven by the generated electric power, the air in the air flow path 21 generated by the fan 18 is heated by the air heating heater 20 and supplied to the hair 13 from the vicinity of the bristle 17.

  In the above case, since warm air is supplied to the hair 13 at the same time as the acidic mist, the hair 13 is acidified according to the state of the hair 13 while drying the hair 13 and setting the hair 13 in the shape desired by the user. Mist can be supplied to the hair 13.

  As described above, since the hair care device according to the present invention can supply an acidic mist containing an acidic component tail according to the pH of the user's hair, for example, animal hair such as wool (fiber or textile) ), Care for dyeing and forming hair, and care for human skin.
