Brenda Christian is our Fairy Browmother!

Universal Brow Definer is a remarkable one-color-fits-all eyebrow pencil that scientifically reads – and automatically color adjusts to – the pH of your eyebrow hair follicle. No joke! Universal Brow Definer is specifically designed to simulate the look of eyebrow hairs. Upon touching the eyebrow area, it automatically color-adjusts from light to dark, warmer to cooler, etc., to match all natural eyebrow hair shades - from Platinum Blonde to the deepest Brunette.

Just stroke Universal Brow Definer over a clean eyebrow area and watch as it automatically changes to the color of your own individual eyebrow hairs, filling in tiny gaps and perfecting your brow shape. Universal Brow Definer even creates a fuller stroke toward the root of the hair, thinning to the end, just like your own natural eyebrow hair. If you have had a hair color service, Universal Brow Definer will refract the hair color you have chosen, causing your new hair color to blend more naturally with your own eyebrows. Though this product is great on its own, for truly "wow brows", follow with Brenda Christian Perfect Brow Gel.
