While standing in the hair color aisle, do you become perplexed by the never-ending sea of choices? You're in luck. Over the next few days, I'll break it all down for you, so that you know the difference between your semipermanents and your demipermanents.
Semipermanent color is composed of smaller molecules that can partially penetrate the hair shaft, but they don't bind tightly onto the hair protein. Therefore, this type of temporary dye typically lasts about four to five shampoos.
Considered rather safe, as they doesn't use developer, peroxide, or ammonia, semipermanents can't lighten the hair, but they can provide color-enhancing effects, with natural-looking results. Scattered grays can be blended away quite easily, but for a head full of white hair, a more permanent product works best. Looking for a semipermanent color to apply? Try Clairol Loving Care ($6) for a quick pick-me-up.
