Excellence Age Perfect Hair Color was formulated specifically to color gray hair harmoniously for a new type of coverage. It adapts to very gray hair differently than pigmented hair, creating natural highs and lows for a layered, tonal effect, as if it was subtly highlighted. At the roots, regrowth is blended with the rest of your hair. The restorative caring formula with pro-keratine complex helps replenish hair from within. Hair feels transformed, thicker, with exceptional smoothness and shine.
