Unlike traditional haircolor, Garnier Olia Oil Powered Permanent Haircolor 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 hair color with 100% gray coverage. Garnier Olia achieves maximum color performance while the oils help reverse roughness and dullness, visibly improving and restoring hair.
