Color Wow Root Cover Up, $35,

If you have roots—even for a day—this powder is going to change your life. You smooth it on and you have no roots anymore, period, until you wash your hair. I’ve tried root fixes before, and they get you by, but they look like paint. This looks just like your normal, everyday, super individual, just-exactly-your-color hair. A roomful of models—each with a different hair color, hair type and root situation—was instantly and utterly transformed. Highlights? Solid gray roots? Your jaw will drop, I swear.
