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.

Awsome for blonde hair
I came across the opalex hair perfector when I recently got my hair alot lighter shade of blonde, it was very dry and not in great condition. I've used this a couple of times now and it's improved the condition and feel of my hair. I used to use deep conditioning masks but this tops it. I normally leave the opalex on for an hour then shampoo and condition normally. I will definitely be purchasing more worth the price even if it is only a little bottle.

Amazing!!
I love all Olaplex products but No3 in particular has saved my hair! I have platinum blonde hair and around a year ago the majority of my hair snapped off. Olaplex has given my hair the strength it needs& allowed it to grow healthily. I honestly can’t live without it now and have incorporated it into my weekly hair routine. I use No0 alongside No3, wash my hair with No4&5 and then use No6 with a heat protectant to dry my frizzy bleached hair.

Saved my hair!!
After going from dark brown to blonde over the 2 lockdowns my hair was frazzled and some parts of it were like chewing gum it was that damaged! I kept googling what I could do to save my hair because I really didn’t want to chop it off and time and time again I seen reviews for olaplex. Soo glad I did because this stuff has really repaired my hair it doesn’t happen over night but being consistent with it really does make it so much better. I could see the repair starting after only one use!! Really good product and if it wasn’t for olaplex my hair would literally so short. Just a shame the amount you get, I have 18” hair and get to use the olaplex 3 times. Very pricey but if you need to save your hair then you should be willing to pay the price

Works miracles
Since using this once a week, my hair is shiny, thicker and easy to dry. My colour is maintained and I have much less breakage from drying and styling. Literally a miracle worker
