Henna brows are a type of stain that colors skin and brow hairs giving you tinted hairs for up to 6 weeks and a tint on the skin that can last anywhere from 2-10 days. It’s a fantastic way to try out a shape before committing to semi-permanent makeup, or if you just want your eyebrows shaped and filled temporarily. Henna brows are the preferred option for those who want to enhance the volume and length of their brows.
