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.

I’ve used this leave in conditioner for a month now and so far it has been great. When I put the conditioner on it leaves my hair feeling soft and looking shiny however I have noticed that the effects are more visible if I put the conditioner on after my hair has naturally dried for a bit instead of putting it on really wet hair after washing it. My family have also noticed the change to my hair and have used the product and said it was a game changer for them in terms of softness. You also don’t need to use a lot of product so this bottle is guaranteed to last me for at least three months.

I am trying to grow my hair down to my bust, but maintaining the condition of my hair has been impossible. My hair is very coarse with split ends. I bought this leave in conditioner 4 weeks ago and have used it every time I blow dry my hair. It's the best conditioner I've ever used. The condition of my lengths between washes is greatly improved but not amazing. It doesn't protect against hot and humid weather, my hair still becomes incredibly frizzy in those conditions. I will be buying this again, I feel sure that when the weather cools down and I start trimming my hair again it will look better. I only use small amounts of the product as it's very expensive.

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.

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.

Love this!! Hair was much smoother, shiny and more healthy. Doesn't make hair heavy plus small amount goes a long way.

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.

My hair was breaking bad. I bought redken shampoo , cinditioner , k 18 and this leave in treatment and my hair is so soft after styling , even my husband is shocked.

Just started using it but seems like a good product

Je suis ravie de mon achat Il apporte une texture soyeuse tout en prenant soin en profondeur de mes cheveux. À voir si cela maintien son effet à long terme

Estou gostando, não pesa no cabelo, ainda não noite diferença no friz

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!

Sehr ergiebiges Produkt – man braucht wirklich nur wenig. Die Haare fühlen sich danach super weich und gepflegt an. Ich bin mega überzeugt vom Ergebnis! Nicht ganz preisgünstig, aber die Wirkung rechtfertigt den Preis absolut.
