N°0 Intensive Bond Building Hair Treatment

Sprays funny- making a real mess, also it's not a life changer- no difference if u use it with no3, or just no3 by itself. Personally, I won't be buying it again.

After using this product, I dont feel it's necessary. I think using the number 3 treatment is enough. I didn't see a big difference in adding this into my routine.

After using this product, I have seen less plants in my hair, my hair is shiny and I have experienced more hair growth. I would definitely recommend this product for healthier hair.

A must have

I received the number 0 in a gift box and never used it , I always would just wet my hair then use the number 3 . I was skeptical at first but it made such a difference . The only con is if you have long hair you can easily use half a bottle and that’s using it conservatively. I would only use this twice monthly for that reason an application aplllla hbbnnnbottle for one application.

Significant difference

I really notice a significant difference when I use this before applying no 3 treatment to my hair. Easy to spray in my hair and doesn't hurt my wrists as I have carpal tunnel and have a harder time with sprays. 10/10 for me

So far I've been using this in the repair bundle. My main issue is the bottle shoots a single stream vs a spritz. In addition, the amount of product I have to use on my thick hair for this is insane. I used this 3 times and the bottle is almost gone. I wish it came in a bigger size.

Good stuff but the spray nozzle breaks every time!

Lost a star because the spray nozzle breaks every time and drives me absolutely insane lol

Totally worth it!

I use this along with Olaplex step 3 twice a week, on wash days, NO EXCEPTIONS! This has saved my hair from breaking after bleaching.

Works well with no. 3

I used this product with the no. 3, 4 and a keratase deep conditioner and my hair has never been smoother, softer or shinier. For everyone leaving bad reviews, are you following the instructions? The no. 0 and 3 are not to be used every wash day, maybe every 1-2 weeks if you’re hair isn’t damaged and you still need to use a moisturizing conditioner after shampooing. I’m not sure if the no. 0 really does anything, you will be fine just using the no. 3.

Good product, but bottle needs an overhaul

I have fine, black hair, and bleaching does some serious damage. I'd definitely say this stuff combined with the No.3 helps with bleaching damage quite a bit. The substance itself is top-tier for a hair repair product. That said, the spray bottle is not adjustable between a smooth stream and a mist, like most spray bottles are. It just sprays a stream. With a product like this, which is supposed to evenly coat the hair, this is the opposite of what you'd want. The stuff winds up on your scalp in concentrated spots, rather than evenly coating the hair. It's gotten to where I don't even use the spray top anymore, and just use my hands. Either way, it's wasteful. This is particularly bad considering this is not a cheap product. I like the company's products, so I'll give them the benefit of the doubt here. But too many companies these days do things like this so you'll consume the products faster and have to re-up quicker, in the name of milking a few extra bucks. For a premium brand I don't think this is acceptable. I hope Olaplex will fix this in the future.

Holy Grail

I use this along with the shampoo, conditioner and No. 3 treatment in my relaxed hair. The products repair the bonds and keep my chemically processed hair strong and healthy. Olaplex is a holy grail product for me! I ensure not to over use the products and have not had any issues. My hair was originally cut into a bob 5 months ago and these products have helped me to retain length.

Please fix the bottle!

Product works amazing but the spray bottle is AWFUL and it makes applying it extremely difficult!!!!
