How to Protect Your Dyed Hair

The chemistry that transforms hair from a mousy brown to a deep chocolate brunette, or from a graying blond to a golden honey, may seem like magic. In truth, it’s a torture test that leaves hair dry, dull, and rough   the very qualities that, ironically, make haircolor look drab. But if you’re one of the 70plus percent of American women who cover their grays or brighten their natural hue, don’t worry: This is one test you can pass with flying (hair)color. Some easy changes in your hair-care habits, along with pro-recommended products, will renew your tresses’ shine and vibrancy and restore your faith in your favorite box of color’s ability to work magic.
