Unlike traditional haircolor, Olia uses an exclusive 60% oil blend, with natural flower oils in the colorant. The unique oil-based formula propels colorants deep into the hair without ammonia, for pure, vivid, long-lasting color. Olia achieves maximum color performance while the oils help reverse roughness and dullness, visibly improving and restoring hair. Number of Pieces: 1. Used For: Hair Color. Product Form: Liquid.
