    chemical substance used to change hair color

    Hair dye, also known as hair color or hair coloring, is a chemical substance used to change the color of hair. It can be applied for cosmetic reasons, such as covering gray hair, or for fashion purposes to achieve a desired look. Hair dyes can be temporary, semi-permanent, or permanent, with the latter involving a chemical reaction that alters the hair's natural pigment.

      community How much does diet affect hair loss?

      in Chat  45 upvotes 1 year ago
