Personally, I'm not fond of the Sergeants brand. In addition to probably needing to have any medical problem elimated, I'd try switching to a different shampoo. Mink Sheen will send you a trail sample, love a company that will do that!! Here's there website,
Touch of Mink Exclusive Skin Care Products just go the the Contact link and send them a note. I'm waiting, oh so
not patiently
, for my sample now.
