Wipe away the color with a damp cotton ball or pad until the dye is totally gone (this may take a few swipes). Use water only, no cleanser or cream of any kind, as those can affect the color, cautions Celaj. Once your brows are clean, assess the end result. If it's too light, go ahead and repeat the process. "It may take a little trial and error to determine exactly how many rounds of color you need to achieve your desired effect," Gafni points out. Once you're satisfied, this is the perfect time to reexamine your brow shape. The color will often bring out fine or light stray hairs that you otherwise may have missed, but can now easily see and remove, says Celaj.
