Review (5/5): Works!
Some two years ago my scalp started breaking out. None of the expensive shampoos with salicylic acid, charcoal, tea tree oil, or whatever, worked at all; quite the opposite, they turned my scalp into an oil slick.
After a month of shampooing with this surgical soap, this issue finally resolved itself.
Along with other reviewers I agree that this soap is far easier and more economical to use with a foaming dispenser. I didn’t went to buy one, but this soap is very liquid and a lot gets wasted without one.
