Jennifer Lopez, Amy Adams and Reese Witherspoon have it all—fame, fortune and fantastic locks. So it’s no surprise that these three stars top the list of what women across the country want from their colorists. Click on to find out why their hair color is the most coveted.

Brunet: Lopez’s honey brown with golden streaks dazzles on darker skin, says Beverly Hills and Las Vegas colorist Kim Vo. For extra depth, keep highlights thin.

Red: Atlanta salon owner Kelly Van Gogh says a mix of warm reds and light golden brown, like Adams’s, gives a vibrant sheen and flatters most skin tones.

Blond: Witherspoon’s baby-blond tone never looks brassy and works best on light brown to natural blond hair, says L.A. colorist Lorri Goddard-Clarke.
