Six Best Dry Shampoos

Over a humid, hairstyle-killing July week, we tested 20 dry shampoos. Here are the winners

Dry shampoo, a powder or spray that absorbs oil, is meant for use between washings. It freshens style and adds volume. But don’t use it two days in a row, as it will lose effectiveness. Dry shampoo works for men, too, and for women with shorter hair. Just run your fingers through afterward to make sure there’s no visible power. Hold the can 10 inches away from your head for best distribution. Flip hair over and spray on the roots. Brush through, and then do a few allover sprays for texture.
