- Acidic Bonding Concentrate Bond Repair Leave-in Treatment, 150 ml | Professional Bond Strengthening Leave-in Treatment and Heat Protectant for smoother, frizz-free hair.

This is one of those products where you can actually feel the difference—hair becomes smoother, softer, and much more manageable after use. It helps tame frizz and adds a healthy shine without feeling heavy. The bond-repair formula with citric acid works on strengthening damaged hair and reducing breakage, while also giving heat protection up to 230°C, which is a big plus if you style regularly . A little goes a long way, so the tube lasts, but it is definitely on the expensive side. Feels more like a treatment than a basic leave-in—but if your hair is damaged, it absolutely delivers.

Does magic when applied in damp hair! Hair feels soft and nourished ..great value for money

Good product for thick, dry, and frizz prone hair. If you want to style it then I would recommend it combinig it with something like a curl cream but it does what it says which is lock in the moisture for the day. I won't say it do it for 24 hours but good 12 hours and also on the cosly side that's why I deducted 1 Star. Good product tho.

Removes frizz and makes the hair soft

My wife had been suffering from rough and frizzy hair condition from quite a long time. She saw the reviews and gave it a try and within a month, her hair has become super shiny and smooth. She loves this product now. Amazing quality product.

Makes my wavy hair very soft. Does not weight down hair, I have very fine hair still it isn't weighed down by it, though I have read reviews that it weighs down hair. But it doesn't help with frizz. Hair remains frizzy. Cost of the product could be less. Much better products available in reasonable price that gives same softness to hair.

Keeps my hair manageable and soft. Loved it from the first wash itself

I wish I could give zero stars The product is not sealed and looks used. Amazon is not allowing return or replacement or connecting me to an agent. This is complete fraud/scam for such am expensive product

Ich habe sehr lange Haare und wirklich schon so einiges an Pflegeprodukten ausprobiert über die Jahre, aber diese Haarlotion ist ein ganz anderes Level wie alle Spülungen, Masken, Haaröle und was es sonst noch so alles gibt. Es macht die Haare glänzend, geschmeidig, super kämmbar und verringert Haarbruch, kaputte Spitzen und Frizz enorm! War zunächst skeptisch und fand auch den Preis eher abschreckend, aber lieber kaufe ich ein teures und wirklich gutes Produkt, als 10 Günstige, die eigentlich so gut wie nichts bringen und insgesamt mindestens genau so viel kosten. Ach ja, die Haarlotion riecht auch noch verdammt gut!

Buy. This. Product. I stumbled across this while desperately searching for something to help my super dry hair look and feel alive again. And I'm here to say - you need to buy this! I've used it twice, and as someone who never gets complimented on the health of my hair, today I had at least 10 colleagues tell me my hair looked incredible, and asked if I'd had it freshly cut... only thing is, I hadn't! And the only thing I changed was adding this amazing leave-in into the mix. For added context, my hair is fine, wavy and colour treated...and I wash, blow dry and straighten it daily. So you can imagine how dry it gets. But now, its soft, shiny, silky smooth and looks super hydrated and healthy. I cannot recommend this highly enough. Oh, and added bonus it smells great too!

I’ve been using the Redken Acidic Bonding Concentrate Leave-In for a few weeks now, and it’s become a staple in my routine. My hair is colour-treated and tends to get dry and frizzy, especially after heat styling, but this product has made a noticeable difference. The texture is lightweight and creamy, so it spreads easily through damp hair without leaving any greasy residue or weighing it down. A little really does go a long way – one small squeeze is enough for my medium-length hair. After blow drying, my hair feels smoother, looks shinier, and the ends appear much healthier. It also doubles as a heat protectant, which is a big plus because I straighten my hair often. Since using it, I’ve noticed less breakage and fewer split ends. The scent is subtle and salon-like, not overpowering. I also appreciate that it helps balance pH and repair bonds – it feels more like a treatment than just a styling product. Overall, I’d highly recommend this if you’re dealing with dryness, damage, or just want to keep your hair strong and protected from styling. It’s definitely worth the price for the results.

best product i’ve ever used on my hair

I love this product. From the very first use, you can feel a small difference, but by the third consecutive wash, my hair felt completely restored. My hair was extremely damaged and processed from bleach since I enjoy fantasy colors. I try many products, but I would call this one my “star product.” The ease of application is great — it spreads well and doesn’t feel heavy. The scent is pleasant without being overpowering. In terms of quality, it feels professional, and it definitely improves hair elasticity, making my hair softer and less brittle. The appearance of my hair looks shinier and healthier after each use. For longevity, I’ve noticed the effects last between washes, which is rare for repair treatments. The price is high, but in my opinion, it’s worth it for the results.
