2. Description of the Related Art Conventionally, the problems to be solved by the invention
For the purpose of coating the split ends of hair, dimethyl silicone gum, polyvinylpyrrolidone-based polymers, acrylic acid-based polymers, polysaccharides, polypeptides and the like are blended in hair cosmetics.

However, when dimethyl silicone gum is blended, there is a drawback in that although the feel is good, the effect of adhering the split ends is poor. In addition, when other polymer compounds are mixed, there is an adhesive effect, but once peeled off, the effect cannot be reproduced, and there are many problems on the tactile surface such as squeaking, dryness and stiffening. Moreover, there was a problem in appearance such as flaking.

Therefore, there has been a demand for a hair cosmetic composition which solves these problems and gives a good feeling to the entire hair.
