Red hair is one of the most difficult colors to remove from hair. There are a few things that can help cancel out the red, but it is important to know that it may not be possible to completely remove the color. One way to try and remove red hair color is to use a clarifying shampoo. This type of shampoo will help strip away any build-up on the hair, including color. Another way to remove red hair color is to use a bleaching kit. This will lighten the hair overall, which can help reduce the intensity of the red hue. If neither of these methods work, then it is likely that the only way to completely remove the red hair color is to cut off your dyed locks and start fresh with new growth.
