REDKEN Acidic Bonding Concentrate Leave-In Treatment, Bond Repair for Damaged Hair with Heat Protection

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.

Cannot recommend this enough! It is the single best thing you can use on your hair! I've tried it all and this is saving my hair right now. It's no longer full of static and feels so healthy. It also smells incredible! I have very fine hair and this being a heat protectant too is so good for me as I dont have to layer another product on top.

I discovered this leave in conditioner about a year ago and now it is the only one I use. It isn't cheap (that's why I didn't give it 5 stars) but it works for my really dry hair. It makes my hair so moisturised and easy to style. Sometimes I use it on dry hair as well, not at the roots obviously. Redken is a brand that doesn't disappoint

Great pricing for the product but the product its self is 10/10!!! I love it it really nourishes my hair with my curly hair or when i straighten it. Smells great and a little goes along way while also being lightweight leaving my hair super soft and shining keeping it healthy.

Amazing product, brought original from a hairdressers, but so much easier to order here. You can see the difference in your hair from the first use, sleeker and less frizzy, and seems to stop those split endx in their tracks Pop it on, style and go, it's just that easy. Love it!

Great conditioner, leaves the hair smooth as silk and stops it being fly away.

My hair definitely feels soft but I find when straightening it it doesn’t look as smooth as it usually does. I’ve been using it for just over 2 weeks along with the acidic bonding shampoo and conditioner, the shampoo and conditioner are really great but my hair seems a bit bulky when using the bonding leave in conditioner. One thing I must add is that I don’t have the breakage anymore there’s no loose hair on comb or brush so that’s good.

This redken leave-in treatment is such a game changer for me. For context, my hair is very fine, and my lengths reach my bra strap. I've been using this consistently for 9 weeks. I'm devoted to Olaplex no.3, but recently I went abroad and didn't have time to do the pre-treatment and then shampoo. This leave-in treatment is fantastic. I didn't register the effect it had on my ends until after I'd used about 3-4 times, and then bam! my ends now feel smoother and silkier and bizarrely enough the end of my ponytail feels thicker too. My grey shines and also feels very soft, and my ends don't catch at the end of the brush as it slides through it. I suspect this is because my ends aren't breaking off as easily and the friction from my hairbands are not getting to do as much damage as before because of this leave-in (I don't know, I'm not a hair scientist). What I do know, is my hair feels tremendous, it brushes out without tangles or knots, and it feels like it's in fabulous condition. The smell is also so light and fresh, like others have stated a salon smell, but nothing overpowering and doesn't interfere with perfume etc. also the scent doesn't change over time, especially if I happen to be lazy and not wash it for 3-4 days. A little bit also goes a long way, pretty much like olaplex 3, an amount the size of 20p piece, and it covers my long hair quite well. Now this isn't a cheap product, but given the change it has made to my hair I feel it's worth the spend. I will in future look out for Amazon price drops on it. All in all, a brilliant product!
