Rebond Xtenso — L

Permanent chemical straightening that breaks and reforms the hair's internal bonds into a pin-straight structure that lasts until it grows out — the salon's strongest straightening option, best suited to very curly, wavy, or frizz-prone hair that wash-and-blow styling can't tame long-term. L covers mid-back-to-waist length hair, close to 3.5 hours total.
