Eyebrow tinting is the process of applying semi-permanent dye to enhance, shape, and define your brows. Brow tinting allows a professional to manipulate the brow area by darkening the fine hairs that surround the perimeter of the brow to increase the width. It also allows the specialist to darken the fine hairs in the inner core of the brow that are in less dense areas. This creates a longer brow line (brow tail) or fuller front and a more ideal shape.
