Most at-home hair masks simply coat the surface, giving temporary softness that disappears after the next wash. Olaplex No.3 Hair Perfector goes deeper, targeting the broken bonds inside the hair fibre to visibly improve strength, smoothness and resilience over time.

Powered by patented Bis-Aminopropyl Diglycol Dimaleate, Olaplex No.3 helps rebuild disulphide bonds damaged by bleach, colour, heat and everyday wear. Supporting conditioners like cetearyl and cetyl alcohol provide slip and softness, while aloe, panthenol and jojoba seed oil help boost hydration and shine without heavy residue.

This treatment has a rich, creamy texture that spreads easily from roots to ends on damp hair without dripping. Hair feels cushioned and conditioned while the formula works, then rinses clean to leave lengths feeling smoother, more manageable and less brittle after drying.

Use as a pre-shampoo treatment on damp, towel-dried hair to maximise contact with damaged areas. Apply regularly, at least once a week or more often on compromised hair, to maintain bond integrity and support long-term strength.

Patented bond-building technology targets internal disulphide bonds rather than just coating the cuticle.Compatible with all hair types, textures and chemical services, including coloured and chemically treated hair.Supports improved breakage resistance for hair exposed to frequent heat styling and chemical processing.pH-balanced to work in harmony with the hair fibre and other Olaplex steps in a routine.

For a complete bond-care routine, use No.3 before cleansing with Olaplex shampoo and following with Olaplex conditioner and leave-in stylers. Layering the system helps maintain bond-building benefits between professional services.

A clinically respected bond-building treatment that helps hair look stronger, smoother and less damaged with consistent use.

• Step 1. Apply to damp, towel-dried hair before shampoo or conditioner, ensuring hair is not saturated with water.
• Step 2. Work a generous amount through from roots to ends, focusing on the most damaged or fragile areas.
• Step 3. Comb through with a wide-tooth comb to distribute evenly and ensure every strand is coated.
• Step 4. Leave on for a minimum of 3–10 minutes; for very compromised hair, extend up to 30 minutes.
• Step 5. Rinse thoroughly, then follow with shampoo and conditioner as usual.
• Step 6. Use once a week on normal hair, increasing to 2–3 times weekly for heavily damaged or processed hair.

Pro Tips

• Apply to clean, product-free hair for the most direct contact with damaged bonds.
• Avoid diluting with water or mixing with other products so the active technology can work at full strength.
• Concentrate extra product on mid-lengths and ends, where mechanical and chemical damage is usually greatest.
• Pair with reduced heat styling and a heat protectant to help maintain results for longer.
