Leave-in Treatment, Repairs & Protects Colour-Treated Hair, Acidic Perfecting Concentrate, 150 ml

A really good leave in treatment, especially for dry, damaged or frizzy hair. It helps make hair feel softer, smoother and easier to brush, with a nice healthy looking shine. The creamy texture spreads easily through damp hair, and the added heat protection is a useful bonus when blow-drying or straightening. One thing worth mentioning is that you only need a small amount. Using too much can leave hair feeling a little heavy or greasy, particularly if you have fine hair. The only real downside is the 50ml tube, which is quite small for the price. However, because you don’t need much per application, it can still last a reasonable amount of time. Overall, a good quality treatment with some lovely benefits for dry and frizzy hair, although I wish the tube was a little bigger for the price.

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!

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.

It's nice. It smells great and works well but I think it's over priced for what it is.

I love this stuff. It's very light and doesn't make my hair feel heavy or sticky or unwashed. It smells delicious too. It's very easy to use, I just work it through my mids and ends, paying special attention to the ends, and then a sweep over the roots to mids when I've got almost none left on my hands, then brush through. After that, my hair feels soft and moisturised. My hair feels really shiny and doesn't get greasy at all. For reference, my hair is bleached blonde, long (below shoulder blades), a little thicker than average, and wavy (2b/2c). Given how little you use for each wash, the price is actually very good when you look at a per use basis - especially if you pick it up on Prime Day!

leaves my hair feeling soft and there is noticeably less frizz after blow drying, it also smells very nice

After reading the reviews i was expecting amazing results. My hair is naturally straight, fine , it is not coloured and i do not use heat. It doesn't make my hair greasy, it is easy to use, small bottle will be enough for a long time... yet it didn't make any difference on my ends... i had my hairdresser polish my hair ant then started testing the product. my hair is still dry, feels damaged and tangles easily. Absolutely no positive change. I almost finished the bottle so i had enough time to give it a go. I will ny buy again

I don't even know what this product is, but it has instantly fixed my frizziness and fly aways on quite damaged white blonde hair.. it's at least an 80% improvement. My hair cannot leave the house I straightened but with this on, it actually looks presentable enough which is wild. Really shocked and surprised. Love that it's heat protecting too. I'll be buying it again for sure but this bottle should last a good amount of time.

Auf Empfehlung von meinem Friseur habe ich mir diese leave in Pflege gekauft und ich liebe Sie, ich habe blondierte Haare /Strähnen und gebe ein bisschen von der Lotion ins Handtuch trockene Haar und man kann ohne Probleme das Haar sofort durchkämmen ohne einen einzigen Knoten. Arbeite es mit den Fingern ein wenig ein und verteile es dann mit der Bürste nochmal gleichmäßig überall, es riecht mega gut und die Haare fühlen sich einfach nur gepflegt an. Ist zwar etwas teurer, aber jeden Cent wert

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

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.

Mycket bra leave in balsam, god doft.
