Control shampoo is an extremely effective anti-dandruff treatment containing more than twice the active ingredients and none of the tar found in other dandruff shampoos – in fact, Control is formulated with the maximum active ingredient allowable without a prescription. The rich lather and sophisticated fresh scent of Control is also unlike any other treatment shampoo, leaving hair healthy and moisturized while effectively eliminating dry, itchy scalp. pH 5.0 to 6.5.
