Description

The present invention relates to a hair cosmetic.

In recent years, various treatments for hair are generally performed due to high awareness of hairstyles. Specific examples include heat treatment with a hair iron and chemical treatment with a perm / hair color. However, these treatments cause damage to the hair, which can cause dryness and poor combing. Therefore, there is a demand for hair cosmetics that are more slippery and more organized.
The most common care for the hair is to apply the treatment after washing the hair in the bathroom and wash it off. In this method, the condition of the finished hair depends greatly on the treatment used. In order to obtain a higher effect, it is important that this treatment stays in the hair moderately even after the treatment has been washed away and exhibits its effect.

For the purpose of sustaining the effect on the hair, as a conventional technique, a method using complex formation of a cationic compound and an anionic compound is known (Patent Document 1). In addition, there has also been proposed a hair cosmetic that can maintain the unity feeling of the hair tips while preventing the sticky feeling of the hair by using an acrylic polymer and a silicone compound in combination (Patent Document 2).
