STREAK out and STRAND out from the crowd. Rock your new look with these 2oz versions of our high quality semi-permanent dye! Even though you’re in the Front Row, this purple color is so electric, you’ll surely be spotted anywhere in the crowd! 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.
