Build up where? Not with this product! The Liquid Black Soap & Hemp Shampoo from The Butterland is a great cleanser. It will clean without stripping your hair of its natural oils. This product works BEST with the Aloe Hydrating & Detangling Conditioner from The Butterland.
Black Soap sourced from Ghana, Hemp & Tea Tree Castle Soap, Water.
I really like how it works but I’d love a bigger size. May be the best shampoo I’ve tried.
