The Olaplex No.3 Hair Perfector is a best-selling pre-shampoo treatment powered by scientifically-proven Olaplex Bond Building Technology™. Enriched with a host of revolutionary actives, the high-performance formula helps to hydrate and visibly smooth hair, promoting a stronger-looking and more resilient appearance.
With a pH balance of 3.5-5, the weekly at-home treatment works to restore a satin-like shine and soft texture to dry, damaged hair. Simply comb the radiance-boosting Olaplex treatment through damp hair, allow it to work its magic for 10 minutes, and then follow with your usual wash routine. The hair appears visibly nourished, exudes a glossy sheen, and feels luxuriously smooth.
- Application: Apply generously to damp hair from scalp to ends until hair is thoroughly saturated. Leave on for a minimum of 10 minutes (or longer if desired). Rinse from hair. Cleanse with OLAPLEX Nº.4 Bond Maintenance Shampoo and OLAPLEX Nº.5 Bond Maintenance Conditioner.
- Routine: Use once a week or 2-3 times a week for very damaged hair.
Pro Tip: Use OLAPLEX No.0 Intensive Bond Building Hair Treatment before No.3 Hair Perfector™ as a two-part system.
- Original Bond Builder System: Patented technology that helps leave hair feeling stronger

How to use Olaplex 3
Designed to be used once weekly, distribute the pre-shampoo treatment onto damp hair before washing and comb through for even root-to-tip saturation. Leave it on for a minimum of ten minutes and a maximum of 90, depending on how damaged your hair is. Rinse, then follow with Olaplex No.4 Bond Maintenance Shampoo and No.5 Bond Maintenance Conditioner. Dry and style as usual with your favourite Olaplex products.
Can you leave Olaplex 3 on overnight?
It is not advised to leave Olaplex No.3 in the hair overnight, as the formula is intended to be rinsed out and followed by a shampoo cleanse. The brand suggests that just ten minutes is long enough to notice visible results.
What does Olaplex 3 do?
Olaplex No.3 is a pre-shampoo perfecting treatment that nourishes all hair types, including coloured and chemically treated. Thanks to innovative Bond Building Technology®, the formula protects against breakage, brittleness and dullness, restoring the hair’s look and feel with a high-shine finish.

A must have
This is a must have product for your hair in my opinion. I use it once a week, usually overnight if I can. My hair feels so lovely after using it and my hair is in great condition with continued use. It’s one of the products I replace as soon as I run out.

It just WORKS
With so many products to chose from, the Olaplex brand just delivers what it’s meant to do. No.3 is the only one you really need to see results immediately, I've tried them all and this bottle gives you most bang for your buck. It’s basically saved my highlighted hair after hairdresser trashed it, it’s been brought back to condition with a couple of uses. You pay for what you get.
