Restore natural, healthy-looking hair with the Olaplex No.0 Intensive Bond Building Hair Treatment. Inspired by professionals, this haircare formula is designed with the following aims: priming the hair for deep repair, rebuilding hair bonds, reducing breakages and protecting the hair’s structure for visibly stronger and healthier locks.

The Olaplex No.0 Hair Treatment is recommended as the first part of a two-part treatment, paired with the Olaplex No.3 Hair Perfector to help strengthen and repair all types of hair. Designed to complement each other, this system works to restore the hair’s healthy appearance and texture by working to repair damage and protect hair structure.

Redesigned for a quick and targeted stream application, the No.0 Intensive Bond Building Hair Treatment features an easy to use nozzle that primes the hair and delivers the highest concentration of the patented bond building technology of any Olaplex at home product.

Use the two-part system once a week or two to three times a week for damaged hair.

SKU# UK300057383


Use as the first step in a two-part at-home system with No.3 Hair Perfector (sold separately) to strengthen and repair all types of damaged hair.

Apply slowly to dry hair, distributing evenly from root to tip. Work No.0 into small sections by squeezing the liquid into the hair to be fully absorbed as you go. Hair should be damp, not drenched. Let process for 10 minutes. Do not rinse. For the complete treatment, apply No.3 Hair Perfector over hair with No.0 applied to it, combing through as needed. Let process for a minimum of 10 minutes. Rinse, shampoo & condition. For best results, use No.4 Shampoo & No.5 Conditioner.

Product Tip: Brush or detangle hair before applying No.0 so it can easily be absorbed. For thick, coarse, or long hair, work in small sections to ensure each area is fully saturated. No.0 bottle should last 3-6 applications, based on hair length and density.

Wonder Product

I bought this after my daughter raved about it. I thought I’d try it for myself. Nice texture and didn’t leave my hair sticky when on my hair. What a difference when washed it out. Y hair felt silky and gangle free. One slight criticism was the spray on the bottle, slightly too dense when spraying, my preference is a finer spray.

Works for me!

This product really worked for me, I wet my hair all over with it, put it under a shower cap and then use it with Olaplex No. 3. After the first use, I thought I saw a difference in my hair but then after the second use, maybe a week later, I definitely saw a difference in my hair- it really helped with postpartum breakage for me. I top up with 2-3 treatments every few months, I think this product is worth it. And it's great now that there is a spray applicator, much easier to apply.

I have a loy of waivy hair, which gets quite frizzy in the humid weather. I use number 0 and 3 together and it works really well. Definitely recommend.

Another top product from Olaplex

I wasn’t sure this was making a difference to my hair when I was using it, but since I’ve run out of it, I have realised it definitely was. I applied it to dry hair (as others have mentioned, the spray nozzle isn’t ideal, you have to hold it close to your hair and almost spray into your other hand to stop it from going everywhere), then applied Olaplex 3 afterwards, and left both on overnight. My hair was left feeling super soft with zero frizz. I definitely plan to repurchase this, another top product from Olaplex
