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.

Game Changer
I don't usually leave reviews but I need to with this. Basically.. I ruined my hair bleaching it from RED to blonde, damage was horrendous I'm talking that almost sticky elastic feel to my hair when you wash it. Bits had broken off, I'm gutted. I bit the bullet and bought Olaplex 3. Like , it's a big thing, I'm skint and didn't want to waste my money. All I will say is it's changed my hair and I'm so happy. Bare in mind it's not a conditioning treatment, it rebuilds and strengthens hair from within. So I just put a hair mask on after shampooing the treatment out. I don't have lots of money but I thought 'you know what I'm treating myself' and I'm so glad I did ,the gamble paid off. Honestly ,if your debating leaving gawjus blonde behind due to damage try this first.

Fab fab fab
My hair is pretty oily on the scalp and dry on the ends and this product is unreal. I wet my hair like stated throughout and then apply generously. I leave it on overnight for maximum results and my hair after being washed feels so soft and smooth. Would recommend this! Only downfall is size and price. It’s a tiny little bottle for a lot of money

Hair Breakage Remedy
I have not looked after my hair in the past couple of months so I have lots of hair breakage. My ends are very wispy and break off easily whenever I brush my hair. Thankfully I have discovered Olaplex and I can already tell the difference after only a couple of uses! My hair feels softer and much healthier. I usually use it as a weekly treatment. A little bit goes a long way, so use it sparingly!

AMAZING!
Absolutely amazing. I was recommended to use this by my hairdresser. I have blonde balayage hair, that is so damaged by bleach and far to much heat. I got stuck in a trap of my hair is to frizzy to let dry naturally (bit like a trashed dolls hair) therefore had to use heat to make it look sleek. But!! After one treatment of using this I saw a difference. My hair looks healthy! Shiny! And not that greasy shiny! I want my hair lighter but need it in good condition. And this is by far doing the trick. Yes it’s a little expensive..but got to pay the price for damaged hair! I’d recommend this for anyone with damaged hair. My routine is. Wash my hair with Moroccanoil moisture and repair shampoo (not condition it) towel dry it and the but it in root to tip, wrap my hair in a hot towel. (It drys and looks okay) then sleep with it in. Wash it out in the morning with both shampoo then conditioner (moroccanoil) and viola instantly healthy looking hair!!! If your unsure..it’s worth a try to find out! I did and it’s paid off

Good but expensive
This is my second bottle. It is very good but it is quite expensive for a small bottle. I’ve started to use it as a leave in conditioner which is good but my hair is very curly. Good for anyone following the Curly Girl Method

Olaplex
Bought this during lock down to help with my long hair getting straggly because it was due a trim. I left it on for one hour and it worked wonders even after the first use. My hair was much softer, shiny and more manageable and sat better after styling. 100% recommend.

Game changer
My hairs bleached so tends to go quite dry on the ends. I Purchased this to see if it would help keep my hair in good condition until the hair salon re opened. I’ve used it once a week for 3 weeks , leaving it on over night and it is amazing! My hair looks like it’s freshly cut, I don’t have any split ends and I haven’t been to the salon since the beginning of March. My hair is really shiny which it normally only looks after it’s been styled after my hair apps. I’ve also found that I don’t need to straighten or curl it as often as I don’t really wake up with frizzy bed head anymore either. Would 100% recommend this.

Worth it
You won’t be disappointed with this product. My hair feels so soft and shiny. It’s a must buy for me

Ok but not amazing
I bought this after bleaching my hair, it has helped but not entirely convinced it’s worth the money. I’ve bleached my hair many times and often use deep conditioning treatments at a fraction of the cost with pretty much the same results.
