This product is great when you've absolutely damaged your hair from head tools and constant colouring. This is the product to rejuvenate your hair back to health ... no magic wand - but works well, is non-greezy and doesn't have that dreaded crunch factor.

I love to use this shampoo it has repaired my hair in the past from colouring damage. I used to have broken and dry fizzy hair now my hair is smooth and it feels soo good. I am not using it to much as it’s also very pricey however it’s worth every single penny

This shampoo helped my hair when I bleached it so much. It is one of the best shampoos ever. It is slightly pricy but it is worth it. It will last you months too as you only need a pea size at a time. It is genuinely such an amazing shampoo. I highly recommend.
