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

I don’t normally leave reviews unless it’s really worth it and this is, I colour my hair regularly and have quite fine hair, my hairdresser recommended this product when my hair became quite damaged through colouring it and heat drying it, wow. I’ve been using the product for a few months now and my hair is shiny and seems much thicker and healthier. You don’t need to put much on to damp (not really wet) hair and boom when you style it looks fantastic. Sometimes I leave my hair to dry naturally and the product is not heavy, sometimes leave in conditioners are crunchy and heavy if you leave them in, this one isn’t, it’s like food for your hair! great hair 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.

I have very thick corse and dry hair. I wanted something that makes it sleek and shinny. I didn’t do this however I did test it on a receipt as a heat protector and it had great results compared to my other dedicated heat protectors. It’s not greasy, very light weight, you really can’t feel it in your hair at all. Smells lush. Kinda pricey but I do think it will protect your hair.

A really excellent product which deals with fluffy hair very well. Easy to use and it smells lovely! It's expensive but lasts ages.

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.

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.

Nice smell and easy to use. It seems to add shine to my hair while improving the texture, however, it is not a life-changing product and yhere might be better products for less value.

Really helps smooth out and soften hair

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

Me encanta este producto. Deja el pelo súper manejable. Si lo aplicas y luego lo secas con secadora queda súper.

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!

Love the smell and how it makes the hair feel after use

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.
