Brow Henna works both on the hair and skin; it is incredibly unique in comparison to tinting. Tinting uses an oxidant to open the cuticle of the hair and allows colour to penetrate the brow hair’s cortex through the oxidation process. Alternatively, henna acts like a blanket over the hair and provides a coating to the hair shaft, coating the top layers of the hair cuticle only. The henna staining will slowly fade off the skin, while the hairs remain coated and darker for longer. Brow Henna is a 98% natural based gentle formulation containing no ammonia, lead, or peroxide and is vegan and cruelty free.
