Neutrogena T/Gel

Stylists and users breathe a sigh of relief with this soothing shampoo that calms an itchy, flaky scalp without a heavy chemical scent. Neutar, a coal-tar extract, treats most dandruff-causing scalp conditions. Stylist Joelle of the Avon Salon & Spa in N.Y.C. calls it "gentle yet thorough."
