I don't know what it is.

Patient's question:

No

Doctor's answer:

Your condition may be alopecia areata, commonly known as "," which is a sudden, localized patchy hair loss disorder. The affected scalp area appears normal without inflammation or any symptoms. The course of this disease is slow, and it can resolve on its own and recur. If all the hair on the entire scalp falls out, you can consider using a decoction of perilla leaves for steam bathing treatment, and rub the scalp with slices of ginger to the point of local warmth.
