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!

I have frizzy hair, which is coloured regularly. I use this with #3 in combination regularly and my hair looks amazing. The price point is an issue though, because I use it regularly, I do keep an eye out for sale pricing. It is truly a miracle product. Flicking my glossy hair as I write this. ;).CONS; the application spout is a bit tricky to use. You can buy a more expensive version which has a spray bottle attached, I would probably buy one of those first then refill with these cheaper non-spray bottles. Personally, I just decant some into a travel spray bottle and use it that way. Instructions say to leave it on for ~10minutes, but I have read online magazine reviews that say you can leave it on for up to 30 minutes. I usually wander off from the bathroom and end up leaving it on for ~20 minutes, then the #3 product for a further 10 minutes, works great for my hair.

Can’t give it five because I used it with 3 olaplex too as that was what it advised Online. For my 50-year-old bleached blonde very dry frizzy hair both of them together are absolutely amazing. Can’t vouch for it on its own but it feels so good when you put it on your hair.. leave it for as long as you can I did it the first time for an hour the next time for 20 minutes a few days apart. Wow, what a difference 3 & 0 make to your hair together when it was as bad as mine! Makes it soooo soft no frizz & more fluffy & bouncy and actually shows a better haircut if that makes sense! All I can say is you need to try it? It may not work for all but it definitely does what it says on the bottle!

It sprays out like my son’s water pistol!I’ve had two applications out of it and it’s nearly gone!!!! It drenches you where it doesn’t spray properly! Absolute waste of money! I wish I’d listened to the reviews I read on it before I purchased! Lesson learned.

3.0 out of 5 stars Decant into another spray bottle

Yet another product that hasn't actually been ran through any user testing first...for the love of god listen to customers and change the nozzle?! Impossible to distribute evenly. I've ended up drenching my hair in this stuff to make sure. Well, I guess they know their customer base are by default going to be desperate enough

5.0 out of 5 stars Olaplex 0,3 & 8

Definitely recommend. I have used the olaplex 0 followed by the 3 then rinsed and shampooed my hair before using the 8 for the first time today. I can visibly see the difference in my hair and it feels healthier. Definitely a product I will be using regularly

A hair changing experience…

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 🫶
