Color correction is an important thing to control as it is such a gradual thing and creeps up so slowly. This is more evident in the summer when the hair is exposed to more sunlight but it occurs at a slow rate all the time. We've always recommended 'Back 2 Natural' color blender as it is specially formulated for hair pieces. It blends the color of your own hair to the color of the hair piece. All you do is put it on a comb and comb through your hair. It's also a conditioner and revives the hair. You can get it on line at: adfhair.com.
