While semipermanent and demipermanent hair colors wash out after several shampoos, temporary hair colors provide just that — a temporary effect. This no-commitment type of color comes in the form of shampoos, gels, rinses, sprays, foams, and mascara-like applicators. Think Beyond the Zone Spike It Hair Cement ($5), Oscar Blandi Pronto Colore Root Touch-Up and Highlighting Pen ($23), and Claudia Stevens Hair Highlighter ($4.30), just to name a few.
The larger color molecules of temporary hair dye cannot penetrate the outer cuticle layer. Therefore, they work by being absorbed into the hair shaft and are easily removed after one shampoo (or two, for those with dry or damaged hair). Temporary color can be perfect for special occasions like Halloween or any event when you might want to try out something different in the vibrant variety. It can also enhance your existing tones and help you get through the rough times in between hair color appointments. Added bonus? Your underlying hair remains untouched.
