No. 3 Bond Building Hair Perfector: Concentrated Pre-Shampoo Treatment | Repairs Damage & Strengthens Hair | Rebuilds 3 Hair Bonds | For Coily, Curly, Straight, and Wavy, 100 mL / 3.3 Fl. Oz.

My natural hair is silver. I had coloured it copper then remembered the roots argh!!! Cue several rounds with the hair dresser to bleach it to make wearing it between highlights easier. My hair is strong but the last round really wrecked my curl pattern. They didnt curl, they were maybe a loose very fluffy wave. I took a chance on this. I applied it, shoved on a shower cap and waited 1 hr. Washed, conditioned with my usual shampoo and conditioner. I couldn't believe my eyes, my curls are back and look amazing. I really am shocked but so happy. I am absolutely going to buy again as I am enjoying the highlights with what grows out my head and this stuff works. In my opinion it is worth the £28. But I do have a bob about mid neck length so I will get about 6 uses out of a bottle.

This product made my hair feel new! It is a tiny bottle but a little goes a long way.

I tried Olaplex No. 3 Hair Perfector when my hair was in serious trouble. Bleached, heat-damaged, and frizzy everywhere, it felt like straw and every brush stroke was a small tragedy. Decided to give this bond-repair stuff a go, and honestly I’m impressed. From first use I could feel my hair softer. I applied it after washing but before conditioning, left it on for about 20 minutes with a towel wrap, then washed out. My ends, which were previously dry and crispy, felt way smoother. The frizz calmed down noticeably, and I didn’t have that crunchy stiffness I usually get after drying. What’s cool is how this treatment goes beyond just surface-level shine. The active ingredient olaplex uses (bis-aminopropyl diglycol dimaleate) claims to repair the internal bonds, those disulfide bonds that bleach and heat are always wrecking. Reading reviews, lots of folks say hair is stronger, less breakage, maybe even more elastic. For me I saw less shedding in the shower, which is always satisfying. It’s not perfect though. The smell is a bit strong kind of chemical-y, so if you’re sensitive to smells it might bug you. Also if you use too much or leave it on super long, it can weigh finer hair down, make roots greasy or limp. So using just the right amount and rinsing well matters. And it’s pricey worth it if your hair really needs help, maybe less so if your hair is already pretty healthy. All in all, this is a keeper. It’s not magic overnight, but with consistent use once a week, my hair’s gone from limp and damaged to manageable, smoother, healthier-looking. If your locks have been through the wringer, this will make you feel like you have them back.

My blonde highlighted hair is over bleached, over straightened and has been damaged by the winter weather. Every time I brushed my hair I was finding broken bits everywhere. It looked like I’d had half a fringe cut in as the front of my hair had broken so badly. My hair is really thick, so this is the first time this had happened and and I only have my highlights done about every 8 weeks.... I’d used supermarket deep conditioners which didn’t really do very much. Someone suggested Olaplex - my understanding is that this one (number 3) is really only supposed to be used after you’ve had treatments 1&2 in a salon, but I thought I’d have a bash with number 3 on its own anyway. The bottle is TINY - it’s only 100mls, so you’re not getting much for your money. Amazon also helpfully put their own sticker over the instructions on the back so I had to google what to do with it. I think there’s a few ways to do it, but I got in the shower, wet my hair but didn’t shampoo or condition it. Wrapped it up in a towel, let it towel dry for half hour or so. Put a generous amount of Olaplex on (enough to feel it in my hair - my hair is very thick and quite long and I only used about 10% of the bottle) and combed it through with a wide tooth comb. I then wrapped it up in cling film for a few hours and then slept in it. Next morning I rinsed off in the shower and shampooed and conditioned as per the instructions. In all honesty, there’s not ‘much’ difference. It’s certainly not the miracle cure I’d hoped for in one wash as there’s still a lot of broken hair when I brush. Saying that though, I’ve still given it 4 stars as my hair does feel a bit softer and I suppose the front does look a bit less frazzled. Again, I think number 3 is supposed to be used as a top up after 1&2 at a salon so it was probably never going to work 100%. I think I’ll use it once a week and see how it goes. Ultimately, if you don’t have time or funds to get to a salon for 1&2, it’s worth a bash as it’s definitely better than the supermarket deep conditioning treatments.

Having had highlights recently (which came out too light and pretty much fried a lot of my hair especially around my face), I decided to give this product a go. My regular masks just weren't doing it. Easy to apply, on towel dried hair, and I left it for about an hour, combing it through. Washed and conditioned my hair, and OH MY GOD what a difference this has made. My hair is smooth, shiny and the fried frizzy look has completely vanished. The bottle is small, and yes, it's a little pricey, but in my opinion it's worth every penny.

This saved my hair from snapping clean off. I have just bleached my hair from dark brown to platinum. The first bleach went well But the second bleach burnt my hair off. It felt like melted plastic. So i ordered this olaplex and even after the first use there is a noticeable difference in my hair. By all means it is not fixed it... but it did stop it all breaking off. I've been trying all kinds of treatments & masks but this is definitely the best so far. Expensive but definitely worth it if your hair is badly damaged.

Transformed my hair, after bleaching it was so damaged and broken. This made it so much softer to the touch and repaired the split ends after one use very good. Onlt need to use it once a week

The price seems steep but the product really makes a massive difference in improving the texture, frizz level and overall appearance of your hair. I used it ask a mask once then just used it on my ends now and again to conserve the product. The smell is lovely and it lasts a long time, I get complimented on the smell all the time. I put a three star rating as in america they allegedly had a (now banned) ingredient which can cause infertility, I don't think this was present in the EU products, at the time of purchase the UK was part of the EU and they allegedly could not use this particular ingredient in the UK products - but I would just double check this! Other than this the actual product was great and I think since finding this out olaplex have removed this ingredient.
