Glossary Permanent Hair Dye

chemically alters hair pigment for long-lasting color

Permanent Hair Dye, also known as Permanent Hair Color, is a type of hair coloring product that chemically alters the natural pigment of the hair. It typically contains ammonia and peroxide, which open the hair cuticle and allow the color to penetrate deeply into the hair shaft, resulting in long-lasting color that can cover gray hair effectively. This type of dye does not wash out and generally requires new growth to be touched up.
