Brow Henna is one of the most gentle and effective ways to dye eyebrows. During this treatment, eyebrows are perfectly shaped, dyed and neatly finished with eyebrow makeup. The advantage of Henna is that both the hair and skin are colored, so we can create beautiful, full brows. The henna we use for eyebrow tinting is of the purest form, meaning no ammonia, no lead and no harmful chemicals. The Perfect Brow Henna is also Cruelty Free and free of parabens. The Henna is visible for 6-8 weeks on the hair and about 5-10 days on the skin (depending on skin type).
