Olaplex Nº. 0 Intensive Bond Building Hair Treatment: Primes & Strengthens | Repairs & Protects Hair | For Coily, Curly, Straight, and Wavy, 155 mL / 5.2 Fl. Oz.

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!

Good product

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 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!

Makes hair soft but the spray bottle is ridiculous. One squirt wastes almost half the product. Buy another brand.

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.

We deserve it.
