A keratin treatment is a chemical process that smooths and shines frizzy hair. “Some will straighten the hair completely, while others work to relax and loosen the curl shape,” explains celebrity hairstylist Harry Josh, Goldwell & KMS ambassador. Think of it as a “topcoat” for hair, advises IGK co-founder Chase Kusero. “Hair gets frizzy when the outermost layer of the hair, called the cuticle, lifts. This allows for moisture and other environmental factors to seep in, swelling up the hair shaft and making it thick and frizzy. By permeating the hair with a keratin treatment, you’re smoothing down the cuticle and sealing it up, therefore preventing frizz and breakage.”
