The basics The original genius stencil tool gives anyone perfect, foolproof brows in seconds. The benefits Classic stencil shapes work for virtually any brow. Powder colors blend to mimic natural brow hair. It's great as a tweezing guide.  The uses It’s a must have for shaping and coloring sparse, faint, thinning, and over tweezed brows. Covers gray hair and is ideal for hair loss after chemotherapy or natural aging. To use Form-A-Brow® as a tweezing tool: Use a stencil and the darkest of the 3 colors, heavily color in the brow shape on top of your brow. Remove the stencil and tweeze the hairs outside of the stenciled shape. Remove the powder to reveal the perfectly shaped brow!
