Nº.3 Hair Perfector®

The original at-home bond repair treatment — Olaplex's bestseller

~CGM ModifiedProtein-FreeStep: Treat

Our Take

Olaplex's flagship retail product and one of the best-selling hair treatments in the UK. A pre-shampoo conditioning treatment that rebuilds broken disulfide bonds inside the hair shaft — the kind of damage that causes breakage, split ends, and dullness. Apply to damp or dry hair, leave for a minimum of 10 minutes (longer if needed), then shampoo and condition as normal. It contains silicones, so strict CGM followers should note this is a modified-method product. If your curls are damaged and you're not following a 100% silicone-free approach, this is one of the best treatments on the market.
