My hair is dry, thick and badly bleach damaged so I need a heavier shampoo whilst protecting my colour at the same time. This is great for me. Leaves my hair so soft and manageable. I have the type of hair that you could pour a litre of oil into it, it will soak it up and still look dry so I like the fact this is heavier. I've used many other shampoos by cheaper brands and more expensive but I always come back to this.
Defo not suitable for hair that is thin as it will likely leave you with greasy/heavy hair.
