People are talking about sulfate-free shampoos, but even gentle surfactants (which create suds) can fade color and cause parched scalps and strands. "Lather removes moisture, but a cleansing conditioner contains essential oils that wash hair without stripping. This is what people used before the invention of shampoo," explains Wen founder Chaz Dean, whose latest formula, Summer Mango Coconut, contains antioxidant goji berries and matrixyl peptides to strengthen strands. "After three weeks of using a non-detergent shampoo, you'll see hair like you've never seen before," Massey promises.
