I have a skin condition that is aggravating more in the summer than in the winter months but sometimes year around. I have white spots on my skin, but in the sun i get red blotches that kinda appear like a ring worm and they itch and are uncomfortable. years ago a dermatologist told me to cover my spots with head and shoulders (blue) shampoo let it dry and then rinse off but it didn t help as much as i wanted and wanted?? . Can you help?
