Gel eyebrow dye & liquid OxiBoost set

4 shades, 1 liquid developer - customizable color depth and intensity. The Boostific Build&Lock Gel dye & liquid OxiBoost eyebrow dye set contains all four gel eyebrow dye shades and one 15 ml bottle of 3% liquid OxiBoost developer. The set is an ideal choice for professional brow artists who want to adjust color depth, intensity, and dye consistency to achieve their desired results. One of the unique features of the Build&Lock gel eyebrow dyes is that combining them with different types of OxiBoost developers allows you to achieve varying levels of color depth and intensity. This means the same shade can take on a different character depending on the developer selected.
