Free yourself from hair dye! A pro-grade hair color remover formula that helps gradually and gently remove hair dye. Formulated for semi-permanent and permanent hair color to diminish the unsightly “re-growth” line and instantly lighten your overall shade, for a seamless look during your initial go gray phase. If the hair has been lightened, bleached, or colored to a lighter shade, Go Gray Revitalizing Kit will not return hair to its natural color. Revitalizing Treatment only removes the artificial pigment you deposited onto hair. It will NOT replace the natural pigment you removed when going lighter. Formulated to remove regular oxidative hair color, not formulated for bleached, pre-lightened hair or direct color dyes such as pinks, blues, green purples, etc. metallic dyes or henna.
