We do not recommend altering any human hair products, unless the manufacturer specifically states the product can be dyed or lifted. Most human hair products you can deposit colors 2 shades darker, not lift any colors out. Certain manufacturer's like Jon Renau, produces a color line, where you can actually lift the color. The Renau Naturals (RN) colorization process does not use any bleach or dyes, so it leaves the hair superbly healthy and ready for custom color and highlights, if desired. When you decide to color your wig we always recommend that you consult a licensed stylist.
