N°.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.

Decided to change my hair colour from black box dye to red, needed to bleach the black out because removal stuff didn’t work. I wanted to repair some of the damage and look after my hair a bit. I have very long hair and use 1/4 of the bottle for each treatment and it’s been plenty. Left it on for a hour before washing and my hair feels fantastic

If your hair has been through the wringer – whether from coloring, heat styling, or just general wear and tear – you NEED Olaplex No. 3 Hair Perfector in your life. This product is not just a conditioner or a mask; it's a revolutionary treatment that genuinely repairs and strengthens hair from within. I've been a loyal user for quite some time now, and the difference in my hair's health is remarkable. Before Olaplex No. 3, my hair felt brittle, prone to breakage, and often looked dull. Now, it's significantly stronger, incredibly soft, and has a healthy shine I haven't seen in years. It truly feels like it's rebuilding the integrity of my strands. The magic lies in its patented bond-building technology, which works on a molecular level to repair broken disulfide bonds in the hair. You apply it to damp, towel-dried hair before shampooing and conditioning, leave it on for at least 10 minutes (though I often leave it longer for maximum benefit!), then rinse and follow with your regular wash routine. It's an extra step, but it's absolutely worth the time. A little goes a long way with this concentrated formula, so the 100ml bottle lasts a good while, making the investment worthwhile. Whether you have chemically treated, heat-damaged, or just generally compromised hair, Olaplex No. 3 is a game-changer. It's the closest thing to a salon treatment you can get at home and has become an indispensable part of my hair care routine. My hair has never looked or felt healthier!

I tried Olaplex No.3 hoping to rescue my hair from heat & colour damage. After a few uses, it’s been quite good — but it’s not a magic repair job. --- ✅ What I Liked / What Worked Well Noticeable strength and smoother texture: No.3 targets the internal disulfide bonds in hair — those damaged by bleaching, colouring, heat-styling — to help rebuild structure and improve resilience. After treating and shampooing, my hair felt softer, with less roughness and fewer snags when combing. Reduces breakage & improves manageability for treated/damaged hair: For bleached or frequently styled hair especially, many users (and the brand’s own data) report less breakage and easier detangling after use. Solid as part of a full hair-care system: When paired with a gentle shampoo/conditioner (as recommended), results seem better: hair feels healthier, smoother, and more “alive.” Flexible usage — not too heavy: It’s not a heavy conditioning mask, but a bond treatment; this makes it suitable if you don’t want greasy or weighed-down hair, especially if you wash regularly. --- ⚠️ What Didn’t Work / What to Watch Out For Not a moisture or deep-conditioning fix: No.3 doesn’t deeply hydrate or replace a nourishing mask. If your hair is dry or brittle from over-processing, you might still need moisturizing treatments or oils to get softness and manageability. Results vary — depends on hair type and damage history: On some hair (e.g. heavily damaged, very porous, or over-processed) results are more subtle, or the hair feels “improved but still fragile.” If your hair wasn’t significantly damaged, benefit might be minimal. Not an overnight transformation: Bond-building takes time and repeated use. You may need several treatments before seeing “real” improvement; don’t expect miracle repair after one wash. Needs correct usage for best effect: Works best when applied before shampoo on damp hair, left for recommended time (3–10 min, or a bit more if specified), then rinsed and followed by shampoo & conditioner. If you skip steps or overuse, benefits might not show. --- 🧾 My “Hair Journey” — What I Noticed Used once a week for 4–6 washes. After the second use: combing was easier, hair felt smoother. Over a couple of weeks: less breakage around ends, fewer split ends appearing, hair seemed less dry (though ends still needed extra moisture). On virgin or slightly damaged parts of hair, change was subtle — more shine and softness rather than dramatic strength. On bleached/damaged lengths, the difference was more noticeable. I still use a separate deep-conditioner or oil now and then, especially after heat styling — because bond-building alone doesn’t give full moisture. --- 🎯 My Verdict — Who It’s Good For & What To Expect ⭐ Great choice for: Those with bleached, coloured, or heat-styled hair needing bond repair and breakage reduction. People wanting a “maintenance / repair boost” without heavy masks or greasy feel. Anyone who uses regular shampoo/conditioner but wants extra protection against future damage. ⚠️ Might disappoint if you: Need deep moisture or hydration — for that, combine with conditioners or masks. Expect instant hair transformation — think “repair & improve over time,” not “fix everything in one go.” Have very lightly treated hair — benefits may be minimal. Overall rating: 4 out of 5 stars. Olaplex No.3 is a strong “bond-first-aid” treatment — helpful, noticeable over time, but not a replacement for hydration, care, and proper hair routine.

Really impressed! My hair was in really bad condition - damaged and dry and no matter what conditioners or masks I tried it wasn’t improving. Saw this brand had such great reviews so thought I’d give it a go, and was very pleasantly surprised! After one application my hair was improved! It’s not cheap and the bottle is tiny but you don’t need much. I’ve got below shoulder length thick hair, so do use quite a bit but could probably get 5-6 applications out of this bottle. Interested to try the other products in this range

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.

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

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.
