The Truth About Dyeing Your Hair Rainbow Colors

Over the course of about six weeks, the bright hair color will begin to fade, but there are a few things you can do to keep it as vibrant as possible. The less you wash your hair, the more vibrant your color will stay. When you do wash, make sure to use a product line that is color safe like Shu Uemura Color Lustre Shampoo ($48) and Conditioner ($58). If you really must wet your hair every day, try using a co-wash instead of shampoo like Purely Perfect Foundation Creme ($40).
