Olaplex No. 0 Intensive Bond Building Hair Treatment, Repairs, Protects, & Strengthens All Hair Types, 155ml

Works well does what it says helps promotes hair growth and hair health

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.

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

The product is a great treatment but due to nozzle is quickly wasted as previous reviews note, The water pistol style nozzle needs refining however, I solved the problem by decanting the product into a washed Frizz No More bottle (£1.99 from superdrug) -redundant anyway if you using the Olaplex No 0 & 3).Now you have a perfect spray with a fine distribution. Another cost effective tip is to check technique. Cup hair into your hand (scrunch up) and then direct the (Frizz No More) bottle nozzle into the bunch of hair , repeat all over.Making these simple changes has reduced purchase frequency (sorry not sorry Olaplex) The Olaplex 0 has lasted 2 extra treatments since swopping out the bottle.Hope this helps 🙏

I’m a hairdresser and have used every make and brand of treatments.THIS IS SENSATIONAL.

I use Olaplex products but was not happy with this one. When I used it it wouldn't spray properly came out in a singe stream. I wanted a spray mist over my hair tried moving nozzle to other position turned it to spray on my head it shot out in a single forceful spray into my eye. Obviously concerned as these are chemicalsNot at all happy with product.

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

I over bleached my hair. To the point where it snapped off and left about an inch of hair. (My hair was shortish anyway,at about 6 inches long) .I was scared to even wash it. I left it for a week,then ordered this, using the olaplex quiz,on their website. It directed me to 0 & 3. So you use the 0 first, leave for ten mins, don’t wash off, then add on the 3.After one use I already feel that my hair is saved!!!! Gone is the chewy texture, and the literal snapping off of hair.It still feels quite dry and is porous. But I reckon another treatment or two of this and I will be confident enough to do my roots and the ends will be fine.It’s a real saviour.I would say that I will get at least 8 treatments from this, totalling to just under £50 for the 0 & 3 (both bond builders of sorts) so I would say well worth it!Literally thought I would end up bald a few days ago.Well worth it!!!!!!
