Redken colorist Tracey Cunningham, who’s worked with Bette Midler and Drew Barrymore, suggests a technique called silvering. “Hair is bleached until it’s almost white, then a blue-toned conditioner is applied to remove any yellow tones,” she says. “This creates a light-reflecting shade that helps hair pop against the scalp to give strands a fuller appearance.” A kit we like that comes with the bleach and conditioner: L’Oréal Paris Féria
