A radioactive shade of neon green for all our bitchin and bodacious babes. Good Dye Young's semi-permanent hair dye line combines salon-grade pigments with a nontoxic, conditioning formula that deposits ultra vibrant color. Our 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. Vegan, gluten free, and Leaping Bunny Cruelty Free Certified.
