OLAPLEX No 3 Hair Perfector is the world's most iconic at-home hair repair treatment — the product that started the bond-building revolution and remains the gold standard for restoring severely damaged, bleached and chemically treated hair.

Used by hairdressers and their clients worldwide, No 3 is not a conditioner or a mask. It is a genuine bond-building treatment that works deep inside the hair shaft to reconnect broken disulfide bonds — the same bonds that are severed by bleaching, colouring, heat styling and chemical processing. Nothing else available for home use works at this level.

Apply it before every shampoo and within weeks your hair will feel, look and behave like a completely different head of hair.

How it works: Applied to damp hair before washing, No 3 penetrates the cortex of the hair and uses OLAPLEX's patented single ingredient — Bis-Aminopropyl Diglycol Dimaleate — to seek out and reconnect broken bonds throughout the hair structure. It does not just coat or temporarily smooth the surface. It actually rebuilds the internal architecture of the hair, restoring strength, elasticity and integrity from the inside out.

Results with regular use: Dramatically reduced breakage and split ends, improved elasticity so hair stretches without snapping, softer and smoother texture, enhanced shine, stronger hair that grows longer and healthier, and visibly less damage after chemical or heat treatments.
