Description

Detailed Description of the Invention

[0001]

The present invention relates to a hair styling composition,
More specifically, the present invention relates to a hair styling composition that is excellent in the easiness of making a hairstyle and has good holding power, and can suppress dryness and white dust.

[0002]

2. Description of the Related Art In general, when styling a hairstyle, in order to squeeze wet or dry hair, the hair is blown with a hair dryer. At this time, a set foam or the like mixed with a film-forming resin is used in order to make it easier to squeeze or enhance the durability of the set.

However, the film-forming resin used in the conventional hair styling agent hardens when the hair dries, making it impossible to repair it further, making it difficult to set the hair as desired and forming a solidified film. Since the resin was destroyed, the hairstyle was difficult to last, white powder (flaking) was generated, and there was a feeling of dryness.
