Eyebrow coloring with henna BH Brow Henna allows you to save the effect of tattooing on the skin from 5 to 14 days and up to 6-7 weeks - on hairs. A special formula allows you to paint not only the hairs, but also shade the skin. Features of the dye are that with its help you can create almost any shape of the eyebrows, not based on natural data. Within 5-14 days, henna gently washed off the skin, remaining in the same color, only becoming paler.
