The color: Caramel Twist
Description: Corinne Adams, senior colorist at Serge Normant at John Frieda, is a fan of colors with a '70s flair to them, like this shade seen on Jessica Biel. "Women in the '70s were using natural henna to add shine and color to their hair for dimension, which gave them a natural golden, chestnutty tone," she explained. "The key to achieving this look is for hair to appear effortless, natural, and healthy, regardless of how extreme your color transformation is."
Who it works for: Because it adds warmth to the face, this shade works best on people who have dark hair and fair skin.
Technique: Ask for babylights all over or just from midshaft to the ends of your hair. Your stylist will create blended highlights, very fine in very small sections, to create an even color. Touch-ups are minimal and needed only about every three months.
