I have very thick, highlighted hair and this shampoo (along with the conditioner) make my hair sleek, soft and shiny. An added bonus is that it smells divine. 

I have thick afro hair that I mostly style straight, I’ve tried so many hair products over the years but this one is a standout for me, my hair is healthier, smoother and it smells divine

I had high hopes for this product and wanted to love it - but I just don’t. I echo the comments that talk about a residue. No matter how much rinsing, the roots of my hair always have an icky feeling.  I don’t mind the smell, it’s fine but in terms of how this shampoo coped with my thick hair - lacklustre. I’ve gone back to Kerastase. Expensive trial and error.

My favourite, smells delicious, leaves my hair shiny and feeling full by also very light. I have re bought this already 

My hair is so thick and hard to manage, this is the best shampoo I've used
