In this time i have see a massive improvement in the quality of my hair, less breakage and better strength in my hair i also use the extreme anti snap treatment to help improve the quality of my hair.

Beautiful treatment that won't weigh you down


Smells amazing and doesnt weigh down my fine bleached hair. I love it! Using this in conjunction with the shampoo, conditioner and anti snap treatment... my hair has grown fast and I have no split ends!

Best treatment for damaged hair


I've been bleaching my hair for over 7 years and using packet dyes for even longer. This stuff is amazing at repairing the damage caused. I use it once a fortnight in place of my conditioner and a little goes a long way even on my long hair

Highly Recommend this Product


My hair was in extremely bad condition from continuous coloring and extensions and like the packaging says after three treatments the difference was absolutely amazing, it felt softer, less frizzy and even seemed longer. I have recommended this to many family members and they have purchased also.

Great treatment


My hair was very dry after bleaching and so on. This product made my dull hair very smooth and silky. I am using it every other day and very happy with the results.

Totally Recommend!


Due to many years of bleaching, straightening, blow drying and just generally destroying my hair - I found myself in need of a really good treatment. I use the Redken Blonde Duo Shampoo and Conditioner religiously (as in nothing else is allowed to touch my hair) so I figured they were a safe bet for a treatment. I was so, so right! I apply this once a week, leave on overnight and wash out the next morning. As soon as I brush my hair I can feel the difference. The tangles are less, it feels soft and smooth and even better, when I let it dry naturally the frizz is tamed. This is doing wonders for my hair and I pair it with Redken Smooth Lock Butter Silk Treatment (use that the next night) for a bit of extra oomph, but this is just wonderful on its own too. It smells divine too, like I would probably stand around sniffing the container all day if that wasn't odd. Great value for money, despite using copious amounts weekly, its like the never ending tub!
