Hello, both DH and I use Tresemme deep clean shampoo. It's basically the only thing that really makes me hair and scalp feel clean and not go greasy after a day. DH uses gel daily, I don't use much product and none on my roots, but my hair still feels dirty quickly. My hair is really thick and I absolutely can't be arsed washing it every day, even if it wasn't bad.
But, I know sulphate is meant to be really bad.
So is there an alternative? Preferably fairly cheap?
