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.

The only time my hair has felt this good is when I leave the salon.
I’ve been dying my hair for 20 years and am constantly trying to keep it healthy. Nothing has worked as well as this. I have Olaplex when I have my hair done, so thought I’d give this a try (and had big expects) and have to say I am thoroughly impressed - will definitely be buying again!

Super smooth!
Couldn’t wait to try this on my extensions! And my own hair is beached and damaged so as an all round treatment I found it perfect. Definitely noticed that my extensions and own hair were a lot smoother after the first application and super easy to comb through when wet, hair felt strong and looked shiny but not weighed down, also didn’t get greasy as quickly after using this treatment. I will definitely purchase again!

Great Pre shampoo Treatment
This adds to theOlaplex treatments perfectly & builds on the strength of my hair. Takes a bit longer using a pre treatment & I always seem to be in a rush but worth the extra time as my hair felt softer & more smooth.

A must for damaged hair
I’ve never tried any olaplex products before. My hair is long, super thick and prone to frizz and flyaways. Before I used this, I shampooed my hair and towel dried before saturating my hair with this. I used quite a lot as my hair is thick. I left it ten minutes only- probably could have left it longer- then washed, conditioned and styled as normal. The condition of my hair was a lot better even just after rinsing, usually after conditioner I still have a lot of tangles, but I could get a wide toothed comb through my hair easily. After drying my hair was shiny and a lot smoother. I’m definitely making this part of my regular routine.
