Hair colorers are professionals who specialize in changing the color of hair. They use a variety of techniques, such as dyeing and bleaching, to achieve the desired look. The two most common terms for this profession are dyers (5 letters) and DYES (4 letters). Dyers use permanent or semi-permanent DYES to change the color of hair, while DYES are used to lighten or darken the existing color. Both techniques require skill and knowledge to ensure that the desired result is achieved.
