Best hair product range I’ve ever used. I wash my hair every day, use the antisnap every few days and the strength builder mask every 1-2 weeks and my hair has never been in such good condition and grown longer than I’ve end had it before without all the split ends.

I honestly never write reviews but this product is honestly great. There is no overnight miracle but it gets pretty close - I have fine hair that breaks easily and it seems to be helping to moisturize it and keep it from breaking. I’ll defintiely repurchase!

Arrived fast. Smells lovely. Leaves my salon highlighted hair feeling great. A little amount goes a long way so the tub lasts longer. One of my favourite treatments other than the mega mask.

My hair definitely feels softer so far after a couple of uses, but I think I still prefer the Redken gold All Soft treatment.

My hair was extremely damaged from bleach so I was recommend using this condioner alongside the shampoo it has helped my hair no end my hair isn’t breaking as much as it use to it also leaves it looking and feeling so soft and shiny! I recommend using this as a deep conditioning treatment leaving it on for at least 10 minutes.
