Goldwell Elumen High-performance Hair Color

 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.
