Baldness is somewhat self-healing, especially if the area is small, only 1 or 2 spots, and the scalp is intact, it can usually heal itself.
Baldness is a relatively common hair loss disease in dermatology, and is generally considered to be related to mental factors, such as long-term mental tension, excessive stress, staying up late at night, exhaustion, anxiety, emotional disturbance, etc., combined with a lack of self-immunity, can easily cause baldness. If the patient makes adjustments in life, maintains a normal routine, ensures sufficient sleeplessness, avoids straining, and appropriately relieves stress and relaxes, only one patch of baldness may gradually return to normal function after a few months, and black hair will grow back.
If a piece of baldness does not heal itself after a few months, you should go to a hospital dermatologist for treatment and cooperate with the doctor for medication to improve the symptoms of baldness.
