<s>[INST] I am in my mid-twenty, I have a dry spot on the front of my scalp. The spot in only in one area it is not itcy, nor does it get red or have any other symptoms. I take good care of my hair, not sure why this has not went away. We are not experiencing hair loss either. I am starting to think I would need some treatment, but not sure what it can be. I have a sister who has this same problem, which have lasted years. But it forms as dark circular spot on her forehead,and now my mother has the same spot. We have used anti- dandruff shampoo and no results. Can you explain this? [/INST] Hi welcome to healthcaremagic As the disease is spreading in family, do not share the same comb., towel, soap, and clothing... pesonal hygiene must be maintained..you must be clinically evaluated... consult an dermatologist.. </s>
