Gravedigger will bring you back to life or whatever Evanescence said. A smokey (sleek/supernatural) silver that will keep your look immortal. Good Dye Young's semi-permanent hair dye line combines salon-grade pigments with a nontoxic, conditioning formula that deposits ultra vibrant color. Semi-permanent hair dyes do not damage the hair, in fact theyre super conditioning! GDYs formula combines a high-quality cream base, like a hair mask with essential oil benefits. The color is deposited on top of the hair shaft and acts like a stain that will fade out over time each time you wash your hair. Color can last anywhere from 4-6 weeks. Please note that our semi-permanent dyes will show the best and most vibrant on platinum, level 10 hair.
