Patient's question:
There is no illness.Doctor's answer:
In your case, it may be alopecia areata, commonly known as "" (a sudden, localized patchy hair loss condition). The affected scalp appears normal without inflammation or any subjective symptoms. The course of this disease is slow, and it can resolve on its own or recur. If all the hair on the entire scalp falls out, you may consider treating it with a decoction of perilla leaves for steam bathing, and rubbing the scalp with sliced ginger until it feels warm locally.
