Olaplex No.5 Leave-In Moisturize and Mend Conditioner 5 oz

Repair dry damaged hair while sealing split ends and boosting softness with Olaplex No.5 Leave-In Moisturize and Mend Conditioner 5 oz, a lightweight leave in conditioner designed to provide continuous hydration, heat protection, and bond repair without weighing the hair down. Powered by patented OLAPLEX Bond Building Technology® and a High Adhesion Sealing Complex, this moisture rich gel cream helps strengthen hair from cortex to cuticle while protecting against future styling damage. 

Unlike heavy leave in creams that can leave residue or flatten the hair, No.5 Leave-In delivers intense moisture in a silky gel cream texture that absorbs easily into damp or dry hair. The reparative formula works continuously throughout the day to help smooth rough cuticles, reduce breakage, control frizz, and improve overall manageability.

Specially formulated for all hair types including color treated, bleached, curly, coily, straight, and wavy hair, this leave in conditioner helps seal up to 88% of split ends after just one use while providing heat protection up to 450°F/232°C. Many reviewers especially praise how soft, shiny, and hydrated the hair feels without greasiness or buildup.
