technical field [0001] The present invention relates to a hair cosmetic. Background technique [0002] Hair is known to be damaged by chemical treatments such as dyeing and perming, and as a result, the hair feels poor when touched, such as becoming stiff. In particular, the thicker hair peculiar to Asians can significantly feel the deterioration of the touch feeling. Furthermore, damaged hair is affected by behaviors such as daily shampooing or drying with a blower, which easily leads to modification, swelling, and outflow of proteins in the hair.
