Hair dyes typically have a first component that swells the hair to facilitate diffusion and penetration of the dye into the hair, and a second hair to aid in the generation of the oxygen needed to oxidize the dye to achieve desired hair dye. The agent is mixed and used at a fixed ratio.

Hair dyeing using these hair dyes changes the properties and structure of the hair using melanin pigments, which contain chemical components, and hydrogen peroxide, which are present between the cortical keratin fibers in the hair.

The use of hair dyes is easy to cause allergy to the skin, and not only damages the hair, but also dyes are formed by oxidation polymerization inside the hair, resulting in loss of gloss and gloss and severe damage to the hair. There are drawbacks such as poor texture. In addition, color-generating dyes can cause severe irritation to the mucous membranes and eyes, causing hypersensitivity and rashes from dermatitis.

As the number of consumers who dye their hair has recently increased and the age of starting hair dye for the first time has decreased, the incidence of dermatitis and facial edema is increasing. However, due to the use of hair dyes, mild allergies such as itching and discomfort in the scalp area, or some severe symptoms suddenly appear in hospital, and cases of allergic symptoms are increasing.

In order to solve this problem, hair dyes of various compositions have been developed and researched.
