What is ghost head shaving?

Ghost shaving is actually what is clinically called alopecia areata. Alopecia areata generally occurs in young adults. The main manifestation is the sudden appearance of round or oval hair loss areas on the scalp. The boundaries are very clear. The skin of the hair loss area is very smooth. There is no inflammation, no redness, pain, peeling, etc. Scaling and scarring appear. Generally, there are many reasons for the occurrence of alopecia areata, including genetics, mental factors, emotional stress, immune inflammatory response, endocrine disorders, etc. It is generally believed that high mental stress is the most important predisposing factor. Most alopecia areata can regenerate, but some patients may experience recurrence. Clinically speaking, generally the more extensive the hair loss and the longer the course of the disease, the less chance of regeneration.
