I am a circumsized person. During winters the skin on my forehead and around shaft gets dry and starts itching. The top layer of the forehead skin starts peeling. Last year I consulted a dermatologist who diagnosed it as scabies and gave some ointment. It was ok since. But this month with start of winter the condition has reappeared. What precautions should I take to avoid the dryness and prevent the fungal infections like scabies? PS: I am a regular swimmer and use public swimming pool 3 to 4 times in a week.
