N°.0 Bond Building Hair Treatment | Pre-Treatment, 155 mL | Protein-Free, Color-Safe Pre-Treatment for Chemically Treated Hair; Use Before N°.3PLUS to Boost Repair

My hair was feeling dry, brittle, and completely over processed from bleaching, but Olaplex No. 0 Bond Building Treatment has given it a whole new life! Used as an intensive primer before No. 3, this powerful treatment absorbs deeply into strands to repair broken bonds and structurally rebuild strength from the inside out. After just a few uses, my hair feels drastically stronger, softer, and far less prone to breakage. It has restored so much elasticity and natural shine that my split ends are barely visible anymore! I also love how convenient it is that Amazon stocks the entire Olaplex lineup. Being able to easily order No. 0 along with the No. 3 Hair Perfector, No. 4 and 5 shampoo and conditioner, and No. 8 moisture mask all in one place makes building a complete, salon quality repair routine effortless. This is an absolute must have!

If you're already an Olaplex No. 3 fan, or if you have truly compromised, damaged hair, the Olaplex No. 0 Intensive Bond Building Hair Treatment is a non-negotiable addition to your routine! This product is designed to prime your hair for even deeper repair, and I've found it makes a significant difference. This liquid treatment comes with a nozzle applicator, making it easy to saturate your hair from root to tip. While it's a watery consistency, it absorbs well, and you can feel it prepping your strands. The key is to apply it to dry hair and let it sit for 10 minutes before applying the No. 3 Hair Perfector directly over it (without rinsing the No. 0). This two-step process truly maximizes the bond-building technology. Since incorporating No. 0, my hair, which is prone to damage from heat styling and occasional coloring, feels noticeably stronger and more resilient. Breakage has decreased, and my hair just has a healthier, more substantial feel to it. It really amplifies the benefits of No. 3, leaving my hair softer, smoother, and with improved elasticity. A little goes a long way, especially if you focus on your most damaged areas. While it's an investment, the results speak for themselves. If you're serious about repairing and protecting your hair from the inside out, the Olaplex No. 0 is the foundational step that truly elevates your at-home treatment. Highly recommend using it in tandem with No. 3 for the best possible results!

So i really liked this product the only downside was how it makes your hair feel BEFORE you wash it as it can feel a bit straw like however i found it is making a big difference to my hair retention with less split ends and breakage.

I have been using this for a couple of weeks. Combined with no 3 and then shampoo no 4 and conditioner no 5. Results are good but products are way over priced. But I can see a difference on the days I just use normal shampoo and conditioner. I leave no 3 on longer than it states though. Like up to an hour before I head off into shower in morning. Growing my hair for my wedding. But normally I wouldn’t have even thought of paying this much for hair products.

Very sticky! And makes you cough lol. But it works!

I never wrote reviews. I was dubious about this due to the price but do it! I bleached my hair a lot over a weekend. It was snapping, when wet it was stringy and it felt like straw. It was so bad I was scared to touch it, let alone brush it. I couldn’t put my fingers through it and it was standing up in all different angles, split and it looked devastating. It was the worst I’ve ever seen my hair, I thought I’d have to chop it all off as it was so so bad. I bought this and number 3. Used it once and my hair was silky, strong, no breakage and back to normal, if not better. I cannot believe how good this stuff is. It’s like a miracle bottle. I cannot rate this enough and it is definitely worth the price. That’s after just one use. I’m definitely stocking up

I’ve been a loyal user of Olaplex for a long time, so I immediately noticed that the product I received doesn't seem genuine. The texture, smell, and overall results are completely different from what I’m used to. It didn’t provide the same restorative effects on my hair, which is disappointing. I’m concerned about the authenticity of this item and would not recommend purchasing from this seller.

What can i say? Its ok, doesnt work as well as all that with breaking hair but does impart a degree of smoothness. Hugely overpriced but i guess thats capitalism for ya. Sucks though. Id have thought that the price wouldve come down by now given its popularity but clearly theyre enjoying their huge fat profits.

Hair become soft

رائع

I use this with the olaplex 3,4 and 5 and my my hair feels and looks amazing!

I’ve been using Olaplex No. 0 as the first step before my bond repair routine, and it has been a great addition. The spray applicator makes it easy to distribute evenly through the hair, and it leaves my hair feeling well saturated without being messy. When I follow it with the next treatment, my hair feels noticeably softer, smoother, and easier to manage. It’s especially helpful for hair that has been damaged by coloring or heat styling. A little patience with the process is worth it for the results. I would definitely recommend it as part of a complete repair routine.

Hands down, this is the best hair product on the market. The UAE water had damaged my hair making it fragile and snap easy ( snapping off by the handful every day). Even with a water filter, it still wasn’t enough. After spending thousands of dirhams on other various products trying to make my hair stronger, I should have started with Olaplex from the very beginning. It took around 3 treatments to feel significant strength return to my hair. There is now a normal amount of loss. Even my hairdresser noticed the difference (and she uses 1 and 2 as part of my colour treatment when I get my hair done). I use 0 and 3 together as well as Olaplex Shampoo and Conditioner. It’s a small price to pay for big results. Very happy with this purchase and can’t recommend this product enough. A personal recommendation from me to you 🫶
