Henna brows are a form of eyebrow tinting that is used to stain the skin beneath the brow hairs. The purpose of this is to cast a shadow or create an illusion of depth and fullness in the area, visually filling in any sparseness. Henna is a natural dye. No need for pencils or powders. Combine it with your preference of hair removal, threading or waxing for a perfect combo.
