Hair contains millions of disulfide bonds that give it structure, strength, and stability. When these bonds break due to chemical services, heat, or mechanical damage, hair becomes dry, weak, and prone to breakage.

Olaplex’s patented active ingredient — bis-aminopropyl diglycol dimaleate — works on a molecular level to repair these broken bonds. Unlike traditional conditioners or protein masks, Olaplex rebuilds the hair structure, making it an ideal foundation for lasting health and style.

💬 “Olaplex is not just a cosmetic treatment — it’s science-based therapy for your hair.”
— Celebrity Hair Stylist Tracey Cunningham
