Definitions

• the present invention relates to the field of the treatment of keratin fibres, such as hair, animal hair, or other hairs. It relates more particularly to shaping and keratin treatment devices, forming curlers for hair from animal hair, or other hairs. The invention also relates to a method for shaping and treating hair, animal hair, or other hair.
• the perm is a hair curling technique that can last from 3 to 6 months. It can be done on all hair types. For example short, long, straight or curly hair. Perms are even applied to naturally wavy hair that could do without it.
• a curling chemical product and curlers are used, for example to obtain well-defined curls or waves and this for long periods of time, typically months.
• the first method is the hot perm.
• the hair is impregnated with a sulphite or bisulphite solution. These substances are applied to the curlers which are heated. By heating, typically above 80°C it causes an internal change in the keratin of the hair. By the heat the keratin breaks down by destroying the cystic bridges of the keratin. The hair is thus deprived of its rigidity and can therefore be shaped.
• the liquid is allowed to cool, while holding the hair attached to the curler. During the process of cooling new disulphide bonds are formed, which allows to recover the rigidity of the hair. As a result the hair straightens in its wavy position. This method is no longer used.
• the hairdresser proceeds to neutralize it while keeping the hair around the curlers.
• the hair is rinsed and an oxidizing solution is applied.
• the curing liquids are typically salts of thioglycolioc acid or thiolactic acid.
• Neutralizing liquids are used to remove the hydrogen fixed on disulfide bonds, to reconstitute these bonds and to fix the desired deformation of the hair.
• a third technique is the “warm” perm. It is a compromise between the hot method and the cold method. In this case the lowering of the heat is compensated by the use of more active liquids than those used during the “hot” technique. These liquids contain sulfites and thyoglycolate. The lukewarm technique does not require neutralization.
• the present invention makes it possible to solve this problem by proposing a new type of curler and a new process.
• the invention is embodied by a device forming a curler intended to receive at least one lock of hair or other keratin fibers, having at least one surface for receiving the hair or other keratin fibers, configured to allow forming, from at least one lock of hair or other keratinous fibers, at least two undulations having winding axes that are not collinear with each other and/or of different diameters, the device comprising a distal end and a proximal end .
• the curler-forming device of the invention is made, at least partially, of hemp.
• the advantage of using hemp material, at least for the surface for receiving the hair or other keratinous fibers of the device forming a curler of the invention lies in the fact that, during its implementation, the device forming curler and the hair will combine so that the hair takes all the benefits of hemp while the existing plastic curlers block and bring harmful effects to the hair.
• the curler device comprises at least 60%, preferably at least 90%, even more preferably at least 95% hemp, and even more preferably 100%.
• the curler device has a band that has a length greater than its greatest width, and a thickness less than said width. In one embodiment, the curler device is a solid parallelepiped-shaped band.

• the hair curler device comprises a support on which its hemp part is fitted.
• the device forming a curler comprises at least two branches each intended to receive a portion of said at least one lock of hair.
• the invention is also carried out by a process for shaping a lock of hair or other keratin fibers comprising at least the steps of:
• the step consisting in wetting the hair or other keratin fibers is carried out by wetting the hair or other keratin fibers with water before bringing the hair into contact or other keratinous fibers with the devices forming curlers.
• the step consisting in wetting the hair or other keratin fibers is mainly a step carried out by wetting the hair or other keratin fibers with chemicals after the devices have been placed forming curlers and before the folding step of the device forming curler.
• the method comprises a step of drying at a temperature below 60°C, preferably below 50°C, even more preferably below 45°C, for example around 40°C, and preferably above at 30°C (temperature value ranges between 30°C and 60°C, preferably between 30°C and 50°C, and even more preferably between 30°C and 45°C).
• the width of the curler device, before twisting the curler device, and for any section of the lock along the length of the curler device is 50% wider than the width of the lock, preferably twice as wide as the width of the wick.
• the strands of hair or of other treated keratin fibers are better distributed over the device forming the hair curler and form, during the implementation of the method, only a single winding.
• the process allows a reduction of chemical products while keeping a permanent which lasts.
• the reduction in the consumption of chemical products can be more than 50%, since the methods of the prior art require winding the hair (or other keratin fibre) according to several layers of hair (or keratin fibres) which are superimposed and therefore require more chemicals to treat all of the layers of superimposed hair (or keratin fibres).

• the temperature of the curler must not exceed 60 degrees Celsius. It is therefore essential to use, for example, a drying hood at low temperature, typically around 40°C. Drying at low temperature allows the curler to be dried in contact with the hair gently, and therefore to transfer all the cosmetic benefits provided by the components of hemp to the hair without overheating it.
• An exposure time is imposed for the hair to dry completely. This exposure time is preferably 30-60 minutes.
• the material of the curler 1 during drying in the presence of humidity allows the wick 200 and the hemp curler 1 to combine and provide beneficial substances to the hair.

• the hair can be washed beforehand and be slightly damp.
• the application of chemicals is preferably done on the lock 200 of hair, after the installation of the curler 1 but preferably before folding the curler 1 at least partially in the Y direction of its length.
• the perm method of the invention is similar to a conventional perm method, but the curler is not harmful to the hair and is very effective in giving the hair the shape of the curler 1. Also, when the curler 1 of the invention is used during a chemical perm process, this makes it possible to use fewer chemicals.
• the use of the hemp curler 1 makes it possible to consume less than 30%, preferably less than 50% of chemical products. The reason is that the flexible shape of the curler makes it possible to better distribute the lock 200 of hair and therefore to form a single thin layer of the hair, which generates a reduction in the necessary chemical products.
• the thickness of a thin layer of hair applied to the curler 1 is typically less than 20%, preferably less than 10%, even more preferably less than 5% of the maximum width W of the curler. The most important thing in the process is to make a single winding of the lock 200 of hair with the curler 1.

• the curlers 1 are removed and the hairstyle is finished.
• a curler was made in the shape of an asymmetrical bag having an inclined central section b and having a distal part 1b which comprises an opening and a closed proximal end 1a. This is illustrated in Figure 21.
