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.

Mixed opinion

So I have purchased this product in a gift set. It has definitely made my hair feel better however the design of the bottle is really bad , when you spray it doesn't go evenly on the hair it just goes in one spot a lot of product, you need to wet your hair with it so that small bottle only lasted me for 3 or 4 uses which is not great for the price you pay.

Great product

I bleach my hair every 3/4 months so it has been in need of some TLC. Pairing this will Olaplex NO. 3 has been amazing. The products work so well together. I leave 0 on it's own for around 10 mins and then put 3 on top for around 40 mins and even after only 1 use I could see and feel a difference. It only drops a star for the packaging. I find that when I spray it, the product just goes everywhere and it isn't as fine as I would like it, but it isn't a huge deal.

I love this product for my hair! I dye my hair quite a lot and using this product paired with the No 3 made my hair feel so much healthier and smoother. I think it’s definitely worth the money as a little goes a long way therefore would highly recommend to anybody!

The Opalex No 0 Intensive Bond Building hair treatment is certainly good, but I'm not entirely convinced it is really essential. It is certainly easy to apply - once you have got to grips with the spray nozzle which has a strong spray that seems to go everywhere, but I find just dampening your hair before using No 3 works just as well.

Olaplex no 0

No. 0 has not made a big difference for me. I have used No. #3 many times on wet hair with great success. When I learned of No. 0 I tried i twice. First, I have very thick, wavy long hair and this bottle only had enough for me to use it 2- 3 times. Also, I did not notice a difference when I used No. 0.
