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.

WOW!
First time ever using this today and I can honestly say I’m shocked! My hair feels amazing like brand new! So smooth, it feels like I’ve just walked out of the hairdressers. My hair is very damaged, split ends and looks dry and brittle. Now after using this it looks and feels fantastic. Never used a product like this that works so good! Can’t recommend enough! Definitely will be purchasing again

Must have for damaged hair
After a silly lockdown mistake of dying my hair brown I have had to bleach it to get it back blonde. Resulting in really rubbish hair. This is the only thing that is helping to heal my poorly hair. This with the no6, 7 and 8. All amazing. Believe the hype!

Finally gave in
Been meaning to buy this for a while now but the price has put me off. After reading 100’s reviews I finally gave in and bought it. I have used it twice, once weekly and have already noticed my hair feels healthier and stronger. Can’t wait to see the results with continued use.

AN ABSOLUTE MUST HAVE FOR BLONDES
If you’re a blonde you need this in your life. Damp hair and leave on for an hour or so, rinse and wash hair as normal. I promise your hair will feel brand new!!

The best hair treatment
If you dye your hair, use hair straightener and hair dryer a lot and if you have dry ends- honestly you won’t find a better treatment than this. I use it once a week and leave it overnight and next morning wash it off and enjoying soft and shiny hair! I do use moisturising masks occasionally to deeply moisture my hair, but olaplex treatment does the job by making my hair more healthy!

Wow
Tamed my flyaways and saved my hair. I have fine, long blonde hair bleached with foil highlights and I swim regularly in chlorinated pool. My hair was snapping and breaking off - one use of this and my hair already felt so much healthier. I used a fifth of the bottle and that covered my whole head of hair! There’s nothing to lose in trying this product.
