Hair makeup is a temporary hair color that washes out in just one shampoo. Yes, you read that right. Hair makeup is the answer to your fun hair color prayers. You can have purple hair on Monday and rock green strands on Tuesday! Even better, hair makeup colors can be mixed together to create your own custom shade, so the options are virtually endless. Whether you want to try a wash of color over your entire mane or color only a few strands is totally up to you. It’s the perfect option if you want to rock a new color for a night on the town or test out a new hair color trend without causing any permanent damage.
