I work for a dermatologist and my ex-husband also had this. Sounds like Seborrheic Dermatitis. The H & S Intensive formula (navy bottle) is formulated for this condition. I would start there. If that won't control it, I would go to your doctor and they can prescribe a steriod to help... but you can't use a steroid every day long term without some wacky side effects. (thinning skin etc.) You may be able to alternate CG with some things geared to treat your specific condition... You may have to play around. Best of luck.
