Goldwell Elumen High-performance Hair Color, Ngat6 Bright, 6.8 oz

Elumen, by Goldwell, is the first permanent, high-performance, oxidant-free hair color. Elumen works exclusively with pure direct dyes, which are penetrated deep into the hair and anchored by a kind of magnetic attraction. The positively charged hair draws the negatively charged Elumen dye into the hair. This is why Elumen is longer-lasting than most conventional hair colors yet causes no damage to the hair. It works with no peroxide or ammonia, so there is no need for mixing. results depend on base hair color.
