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.

Healthy shiny hair
I’ve struggled with my hair so much since I became anaemic around 12 years ago. I feel like I’ve tried so many different things including supplements to help my hair become thick and strong again. I’d put off using olaplex for so long because of the price but what a mistake this was! I have now used this product three times since purchasing and I have been to the hairdressers for one olaplex treatment and my hair has never felt as strong and thick or as shiny, even before my anaemia started. I cannot recommend enough, even for people with dark hair. I have black hair so don’t be confused in thinking olaplex is just for when you’re bleaching etc. I will never be without this product. I’ve now invested in the bonding oil too! If you’re hesitant because of the price, don’t be! It’s 100% worth it, and if you make sure you separate your hair on application, you only have to use the tiniest bits each time. I have medium length hair and I get at least 5 uses out of the bottle, my hair isn’t the thickest though.

Olaplex 3
I did notice a difference with how soft my hair felt but I haven’t used it enough so notice any real change to the condition. It is expensive but I would pay it for how soft my hair feels

What would I be without my Olaplex ?
A woman of a certain age decided it was time to go completely grey with a sharp pixie cut. Only trouble was my hair had to undergo a complete bleaching stage, which obviously dried out my hair. Thank goodness for great friends, who recommended Olaplex, a great pre conditioner which has transformed my hair's appearance, it leaves my heath so soft and smooth. Only yesterday I was stopped and asked about the colour, having explained the procedure, I couldn't stress enough how Olaplex helps keeping my hair in such healthy condition. I love this product !!

Average
I was recommended this product, as I was searching for something to strengthen and make my hair less dry. I have wavy frizzy hair and was hoping it may tame it a little. Followed the instructions as per bottle, although I left it in for over an hour in hope of better results. I have been using this twice weekly for the last 4 weeks. I was disappointed as I didn’t notice much of a difference, maybe a little more soft and slightly less frizz but not enough to justify the price tag.

Hair perfect !
I am not sure I have noticed as much of a difference as some of the reviewers but my hair is in very bad condition from straightening and colouring. It definitely feels better after I have used this treatment and it does seem to work better the longer you leave it in and the more product you use

Great
Does what it says it does! But you do need to use each product to get the best results I originally bought the full bundle and this ran out first. Not immediate difference but after a few weeks you do really see results !

Amazing product little pricey
This product is brilliant! It makes my hair feel amazing, highly recommend especially for coloured hair. My ONLY negative is it’s quite pricey for a small bottle which doesn’t last long when you have long hair
