OLAPLEX No. 0 Intensive Bond Building

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.

Enhances the effects of No 3 really well!

I've really enjoyed adding this to my Olaplex routine as it enhances the effect of No 3. It's a thin liquid. I find it easiest to get it on my hair by spraying it directly on freshly shampooed hair, rather than in my hands. It's quick and easy to use and on my long thick curly hair, I can get about 4-5 uses out of one bottle. I'm very happy with this product overall

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!!!!

Absolutely does nothing!

Doesn’t do anything for my hair. I have very long, thick Asian hair that has been bleached both at a salon professionally and at home to a number 8-10 platinum blonde. I needed to use a regular routine of hair masks and only wash my hair every other day. I’ve tried long leave in masks from Amika and To The People and Oribe products and they all help a little bit, especially the hair masks and natural oils I use. I heard so many good things from videos and stylists who use olaplex so I wanted to give it a try and bought the whole set - no. 0, 3, 4,5, 6, 8 - it was NOT worth the cost or time it takes to use these products.

Great compliment to No. 3

A few months ago, I got highlights that just destroyed my hair. While I know nothing can reverse the damage, just one application of no. 0 and no. 3 made a huge improvement, softening the hair and improving the appearance. I removed 1 star because the spray bottle is a total fail. I transferred the contents to one of those continuous spray bottles for a finer mist/easier application.

Don't Waste Your Money

I've been using the No3 alone as a mask for months so I figured I'd get this spray since it's a two-part system. I thought it would add *something* but it literally did nothing noticeable to my hair. I may as well have been just dampening my hair with water because this had no effect. Also, the spray is useless because it is a direct spray, not a misting type spray that hair products usually have. Product only lasted 5 uses because of the wasted product from the spray nozzle.

This made my hair break and become more damaged than it was before using it. I would not reccomended this product.

Good product, awful sprayer

Great product, but bad sprayer. It comes out in a stream, not a mist, so a lot misses my hair or goes straight to my scalp. So much got wasted during the first use that I finally put it in a different spray bottler. With so many people complaining about this feature I don’t know why they haven’t changed it yet.
