Lowenol Emulsion VB provides protection of the dye actives from premature oxidation; This will help achieve more color uptake, greater intensity of color, and reduce dye load. It has extreme pH tolerance, able to withstand both the low pH value of cream developers and the high pH value of relaxers. It is highly substantive to hair and works synergistically with Lowenol WHP’s actives, giving outstanding conditioning effects.
