Dry shampoo: Had its moment. But in the end you just couldn’t get around the basic human need to equate water with cleanliness. The latest thing to forgo in the hair-washing industry? Suds. Lathering up may feel satisfying, but all that sodium-laurel sulfate and detergent is actually incredibly drying and irritating. Which is why celeb stylist Chaz Dean has declared his Hollywood salon a lather-free zone. The salon’s Wen products contain none of the damaging chemicals found in other shampoos, and they purport to retrain hair into a state of optimal health and good behavior. (Ask Halle Berry, Jennie Garth, or Meg Ryan. They’ll tell you it’s true.) Work twelve to fifteen pumps of Sweet Almond Mint Cleansing Conditioner into your hair, comb through, leave in for three to five minutes, and rinse. There’s Wen styling creme and texture balm, but you may just find you don’t need it. The absence of satisfying sudsiness is admittedly a bit scary at first, but look on the bright side. At least you get to rinse it out. Available online at chazdean.com.
