No.0 Intensive Bond Building Hair Treatment™ - Hårplejebehandling

Great! Recommend Some Changes Though.

Great product! BUT the spray nozzle needs to be changed. It should spray not be a jet stream. Also, it takes a lot of liquid to saturate my long hair. The size needs to be larger.

#0 is the first part of a hair miracle

Used precisely the way Olaplex says to use it, this product produces miracles. Used with its partner, #3, my hair no longer frizzes, it feels fuller, has more movement, and I get compliments on how shiny and pretty my hair is. What’s not to love about that?! Strongly recommend!

saved my hair

i color my hair and it has been making my hair dry don't use hair dryer ever olaplex has made a big difference

One star. Do not recommend.

If I could give this product zero stars I would. It has completely dried out my hair, which will now take months to repair. And good luck trying to use a heat tool. Doesn’t work smoothly with this stuff in your hair. Not only that, but the spray nozzle is THE WORST I’ve ever seen on a bottled product. Save your money and buy something else.

Damaged hair

I didn’t correlate the damage that I’m experiencing to this product until I read the reviews and realized it’s exactly what I’ve experienced! I love olaplex products but I used this on my curly hair and now my hair looks and feels damaged. I’m praying I don’t have to cut it all off and start from scratch. I used it alone, so I don’t know if that is what contributed to the damage. I’m going back to no 3 and pray it reverses the damage.

Heals color-damaged hair

Makes such a difference when dampening my hair first with this, then adding in No. 3. I leave the combination of both in my hair for around 30min to an hour then shower with shampoo and conditioner. Makes Wor Really helps bond split ends

Highly recommend!

I only use this when I want to add an extra step to my hair routine and treat myself. I let it sit and then pair it with No. 3 and my hair always thanks me later. My only issue is the nozzle needs to be reworked as it does not distribute as a fine mist.

Burned my skin

I read all the reviews and despite that I was still shocked how bad the package is. It took forever to even open, let alone use. Then, where the product dripped down my face I felt a burning. Then my scalp felt a bit burning. When I looked in the mirror I saw how red my skin was there. The burning and redness concerns me. For that reason I won’t use it again.

Great product - let down hugely by spray nozzle

This is a great product which I use with No.3. I do feel that the nozzle lets the product down significantly though, hence why I have only given this 3 stars. In order to thoroughly dampen the hair, it would be much better to deliver the product via a mist to allow greater control of where the product goes. The jet wets one area whilst leaving other areas dry meaning you have to use far more of the product than you need and you have less control over where the product goes. A mist would be far easier to control and distribute through the hair and far less expensive (better value = better customer experience) and a better user experience overall. At this price, you shouldn't have to decant the product into another bottle with a mister to be able to use it effectively or use twice as much (or more) to get all your hair damp enough.

Bad packaging

I think I love this product. However, I absolutely HATE the packaging. The sprayer broke as I was putting it together. And, why do I have do do this? Sheesh! The other products are hard to open and hard to squeeze the products out.

I love No 0!!

This product is amazing! I applied No 0, followed by No 3, rinsed, and then shampooed with No 4 and conditioned with No 5. I also used leave-in conditioner No 6. The result was soft, smooth, healthy-looking hair! I am so impressed because my hair is usually dry looking and a little bit frizzy on wash day. I have white hair, which tends to be dry, but my hair is soft and shiny. I highly recommend this product!

Not Recommended

recently bleached my hair, and it became extremely weak and damaged. I was looking for something to help repair the damage, and after hearing so many positive reviews about Olaplex No.0 and No.3, I decided to give them a try, hoping they would strengthen my hair. Unfortunately, from the very first use, I noticed a negative change. While rinsing the product out, my hair became extremely stretchy and elastic, like rubber, which is usually a sign of protein overload or severe damage. As I tried to detangle it gently, it started breaking and falling apart badly. I was honestly shocked because I expected this product to help, not worsen the situation. This was a very disappointing experience for me, and I wouldn’t recommend Olaplex to anyone with already fragile or over-processed hair without doing a strand test first. What works for some may not work for everyone.
