I love using redken extremes shampoo and conditioner sets when I have recently bleached my hair. I do notice a difference in hair breakage when I have used this product compared to when I haven't.
I would recommend using this the shampoo and conditioner once or twice a week swapping it out with your other products as it can leave your hair with a slightly odd almost greasy feeling when used constantly. The upside of this is that a set will last you a long time!
So I used this shampoo and conditioner combo religiously for such a long time - too long in fact. I over-repaired my hair and put too much keratin back in that it became snappy and hard! So I had to stop using it for a while. However, before it got that bad the shampoo was amazing. It was soft and light and a little bit translucent so I could tell it wasn't laden down with heavy oils that would only clog up my cuticles. It really worked, and then it over worked (totally my fault, not the products!) so if you have damaged hair then you need to use this range.
Tips: Don't use it too often for a long time
