What It Does: Enhances already existing waves or ringlets by tightening and separating individual strands. Uses moisturizers called humectants to attract water from the air and keep curls springy. "It's like using a mister on your curls," says Lana Hill, technical director for KMS.
What It Doesn't Do:
Create waves in straight hair or ringlets in wavy hair.
What to Look For:
Magnesium and quinoa, which help to tighten the hydrogen bonds in the hair. Also important are the humectants—including glycerin and honey—which draw curl-boosting water from the air.
