Ask a Doctor and Get an Answer to Your Medical Question ASAP
Hello from JustAnswer.
Could you attach a close-up picture of the scalp in this area?
From the description, it could be a Malassezia infection. However, a definitive diagnosis would require an examination and possibly a microscopic examination of a scraping of the scalp. Reviewing a picture is not as accurate as a live examination, but it is usually better than a description. Another option that you can try without seeing your doctor would be a trial of an anti-fungal shampoo, such as ketoconazole shampoo and see if the symptoms improve. The ketoconazole shampoo is available over the counter in various brand names, although the original brand name was Nizoral.
If I can provide any additional information, please let me know.
