Abstract :
Depending on the type of hair color, such as permanent, semi-permanent and temporary, different chemicals are used in the composition of hair color. Ammonia is one of the components of hair dye, which causes the separation of hair cuticles and the penetration of dye into the hair. The first chemical hair dye was made with phenylethylene diamine. People usually dye their hair for two reasons: 1. Hide your gray and white hair and look younger. 2.Change the color of their hair to create diversity and become more beautiful.
