Acidic Bonding Concentrate Leave In Conditioner - Hair Repair Treatment For Weak & Damaged Hair, Bond Building & Strengthening, Smooths & Provides Heat Protection

This leave in conditioner is amazing. My hair was quite damaged after bleaching it but after just a few applications of this product the difference was noticeable. It is on the pricier side but a little goes a long way. It helps control frizz, makes my hair look more shiny and on top of that, it smells great!

I really like this leave-in treatment and use it regularly. It works well with the hair’s lipid layer — my hair feels smoother, less frizzy, and tangles much less after using it. Hair looks well-groomed and polished without feeling sticky or heavy. The texture is pleasant, and the scent is light and clean — not overpowering at all. I personally use a bit more product than recommended to get the result I want, especially on dry or damaged hair. Important to note: this product does not “heal” or repair hair from the inside. It’s more about visual improvement and manageability. That said, it does its job very well — hair looks healthy, soft, and controlled. Overall, a solid leave-in if you’re looking for smoothness, frizz control, and a nice cosmetic effect.

This stuff isn’t cheap but I swear it is liquid gold for your hair! I have been using it for over a year now and leaves your hair soft, moisturized and silky especially if you use it before a blow out. A little goes a long way, I was able to make my first bottle last a little over a year and I have long hair. Great product if you are trying to keep dyed hair healthy throughout using heat products.

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.

I originally bought this because all the girlies on TikTok were raving about it, and I’m glad I gave it a try. I’ve been using it consistently and have been happy with the results. My hair feels noticeably softer and smoother, and I’ve noticed less frizz and fewer flyaways. The consistency is really nice too. It’s creamy and smooth without feeling overly thick or heavy. I also love how much you get in the bottle because a little goes a long way, so I can see this lasting me quite a while so it was a good deal. Also the smell is heavenly. To me it smells like Winter Candle Apple from Bath & Body Works.

I absolutely love this product it soften my hairs easy to use and this product lasts awhile it definitely helped my hair a ton

This definitely helps shorten blow drying and leaves my hair smooth and shiny until the next wash. It helps keep my hair healthy looking and is easy to use. I recommend it.

If you are looking for a few staple products to make your hygiene routine more sustainable, the redken acidic bonding concentrate leave in is life changing and should be in your main hair care routine. First off, it smells so good! Some people say it smells like gummy bears but it doesn’t to me, it smells more like a high end sweet and luxurious perfume that mixes well with other scents. I personally wear a lot of tropical scents/perfumes during the summer and I find that this product enhances instead of cloys with my perfumes. It’s also super hydrating and you can visibly see a difference after your hair drys. Additionally, I have thinner hair and am sensitive to leave ins making my hair oily but this product has never made my hair oily which is impressive in of itself. It’s one of my favorite leave ins because it covers so many bases while smelling so good

het is een goed product. En het wordt snel geleverd!!

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!

Para mí este ha sido el producto del año para el cuidado capilar. Pensaba en hacerme un alisado en peluquería pero tras probar este producto noto que no es necesario. Según lo usas las primeras veces no parece hacer mucho efecto pero cuando llevas un tiempo poniéndolo en todos los lavados el frizz desaparece. Es cierto que yo por lo general tengo el pelo liso con poca onda pero con bastante frizz y este producto me lo ha hidratado tanto que también ha evitado que tenga que cortarme las puntas tan a menudo. Es caro si pero el producto lo vale sin duda lo volveré a comprar en cuanto se me gaste. El pelo queda con mucho más brillo y más pulido. Recomiendo incidir en las puntas haciendo un suave masaje en ellas, aplastando con las palmas de las manos en las puntas del producto. El producto es sin aclarado queda en el pelo y es también un protector de calor.

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.
