Hi, Thanks for posting in HCM. I understand your concern. Looking at the description, it appears that your are having Seborrheic Dermatitis of scalp. Since you are having sore blisters associated with it, it appears that it has been secondarily infected by bacteria and hence it is taking a longer duration to heal. You need to following medications: 1. Use shampoo that contains one or more of these key ingredients: Coal tar, Ketoconazole, Salicylic acid, Selenium sulfide and Zinc pyrithione Use it regularly on alternate days. You should feel better in about a month time. 2. For sore blisters, kindly rinse the wound with mild antiseptic like Savlon and apply Neomycin cream twice a day. In case you are not getting better of these problems after a month, kindly get your fasting and post-prandial glucose levels checked to rule out diabetes mellitus. After that, you can take medical assistance accordingly. Hope the information provided would be useful. All the best.
