After your brows are cleaned up with a wax and trim, a tint is added to enhance the natural brow. Tinting uses vegetable based dyes to deposit pigment to the hairs and skin. By darkening light or blonde hairs, the tint instantly adds volume to your brows! The tint can be done alone if you don't need a wax, and just want to bold up your light brows! Pigment on the skin lasts 3-4 days, pigment on the hairs can last 2-3 weeks depending on skincare routine.
