Is Your Hair Color Working for You—or Against You?

The Makeover: Lustrous Tortoiseshell

The Fix: Highlights that are too bright look unnatural against dark hair and skin, but ribbons of caramel and cinnamon, woven through the ends of Katrina's hair and around her face, bring a soft golden glow to her skin. A gloss will keep the highlights from turning brassy over time (its effects should last about six weeks).

Makeup Prescription: When your hair and skin have deep color, keep makeup shades understated. To enhance Katrina's skin, Rebecca used bronze tones with a hint of peach—on eyes (M.A.C. Eye Shadow in Honesty), cheeks (Wet 'n' Wild Bronzzer Compact in Medium/Dark), and lips (YSL Rouge Pure Shine Lipstick in Sandy Beige).
