CoverAll Developer-20 vol. 4oz

CoverAll 20 Volume is a developer designed to neutralize ammonia (found in all permanent haircolor). By neutralizing ammonia, this stops the swelling of the cuticle layer during the coloring process. Instead, CoverAll fractionalizes color molecules so they can penetrate the hair shaft without swelling the cuticle layer. This product also allows the hair to hold onto color pigment longer.
