Description

Cosmetic composition for hair {Cosmetic composition for hair}

The present invention relates to a cosmetic composition for hair, and more particularly, to a cosmetic composition for hair containing flat bean oil, flat bean hydrolyzate or a mixture thereof as an active ingredient to improve the condition of the hair and thereby improving the gloss and softness of the hair. it's about

Human hair performs a special function depending on its location. That is, the scalp hair prevents damage to the scalp, and the eyebrows and eyelashes have a function of protecting the eyes from sunlight and sweat.

In particular, scalp hair is recently gaining importance as a means of expressing one's own personality and confidence, and as an important factor in determining a person's image.

As a result, as the cost of beauty for the scalp hair naturally increases, the hair itself is under great stress.

Specifically, it has become commonplace for modern people to emphasize their individuality with various colors and shapes by treating hair with chemical agents such as permanent wave or dyeing and bleaching.

However, as a result, the hair is degraded in softness, smoothness and gloss, and dry and crumbly, so attempts are being made to repair damaged hair, improve gloss, and improve softness with hair cosmetics such as hair serum and water essence.

For example, Korea Patent Publication No. 2008-009663 discloses a cosmetic composition for hair using black soybean, which is traditionally known for increasing the gloss of hair and strengthening the hair root.

However, black soybean has a bad smell and is easily oxidized, making it difficult to store.

Therefore, research on a cosmetic composition for hair that can solve the conventional problems and further improve gloss and smoothness is required.
