I purchased the tea tree to use for a pre-shampoo. I have seborrheic dermatitis. The bar soap works wonders on my face so I tried this. My scalp has never felt so clean and been flake free so long. It’s only been a week but I have never went this long without flaking. My hair is also super soft and shiny, and all I have done is oil my scalp like I usually do. Total game changer for me.
