For when you want a DIY pop of color or desire to change hair color daily without damage, without bleaching or permanent dye, and without the messiness of temporary color sprays and dyes. Removes completely with just one shampoo. Great for Halloween, Cosplay, festivals, sports events, spiked/mohawk hairstyles, and everyday. Good on all hairtypes and shades. Cool tip: You can buy and mix these colors to produce other colors. Follow usage suggestions and don't apply to much at once for best results. Please forward pics of your usage results.
