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.

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.

Difference after one wash.
This product has really helped my dry, thick red hair. It felt better after just one use. I left it on for about 45 minutes. The only negatives are the cost and size of bottle. I have long hair and I think at most I will get 3-4 uses from the bottle. That’s why I will only be using it once a month.

Amazing!
First time trying Olaplex - applied to towel dried hair and left on for around 3.5 hours. Hair feels so soft and healthy, right from the first application. I have very long, thick hair which is colour treated and its done wonders for my locks already!

BRILLIANT!!!!!!
BUY THIS NOW!! It’s AMAZING!! So I have thick and curly type 3a European hair that isn’t dyed, permed or heat damaged. But it does tend to be quite dry (which is typical of curly hair). I’ve used it twice over the past 4 days and I can already see a difference - my hair looks even thicker and more voluminous than usual and OMG THE CURL DEFINITION IS INCREDIBLE!! Top Tip: It only works on damp hair so I dampened my hair and saturated it in Olaplex 3 and wrapped it in cling film and left it on overnight. My hair was still wet in the morning so Olaplex 3 had 8 hours to do it’s thing. Then I just used my normal curly-hair-conditioner (Redken Curvaceous). And my hair was perfect after it dried! Throw away all your other hair products! Olaplex 3 and your favourite conditioner is all you’ll ever need!
