An amazing product that keeps your hair silky smooth and soft. I bleach my hair and this serum has worked wonders repairing it and keeping it from splitting and being rough. I use it after every wash.

Beautiful product. I apply to my towel dried hair after washing. I air dry to about 70/80% and then blow dry to finish.It's upped my hair game significantly, much more manageable, not as many flyaways and feels softer and looks shiny without weighing my hair down. Also noticing I can go longer without a hair wash by about a day, but this may be other new additions to my routine.Main stay in my routine for sure.

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.

I never write a review , not unless something really impresses me as much as this product has. I first tried the Redken leave in treatment whilst on holiday in Spain and it helped my hair so much. I have curly hair, thin damaged hair from constantly straightening it every 2 days but whilst on holiday I found myself straightening it every day due to going in the pool with the kids and the acidic bonding treatment saved my hair , it felt amazing after the first use and made it easy to style and look really nice. I’ve recently been learning to take better care of my hair and have been constantly searching for what products are right for my hair and this is definitely something I will be purchasing again and again. I really love it and have recommended it to everyone I know.

Love this leave in treatment, really helps my damaged hair. I didn't use it for a while and my hair looked noticeably dryer and more damaged.

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.

I was surprised at how good this product is, it’s replaced heat protection spray and leave in oil. My hair is in the best condition it’s ever been. It feels and looks strong and shiny. It also holds after I’ve straighten it which is a first. Smells amazing too. If there’s one product you should buy it’s this! Cannot recommend enough

Love this leave in conditioner. Used it for a while now. I use it in-between shampoos but not every week. I have short hair so only need a tiny amount for it to work, lasts a long time
