Head scalp pain may be head trauma, external stimulation, brain hypoxia, folliculitis, herpes zoster, etc., you should consult a doctor in time to find out the cause.
1. Head trauma: head bumps, blunt force trauma may cause subcutaneous hematoma, patients may have symptoms of head scalp pain.
2. External stimuli: high or low water temperature when washing hair for a long time, catching cold and other external stimuli can cause local muscle tension and contraction on the top of the head, stimulating the scalp nerves, causing pain on the top of the head and scalp.
3. Lack of oxygen in the brain: long-term late night, sleep disorders, etc., the patient does not get enough rest, which may lead to lack of oxygen and ischemia in the brain, which in turn triggers pain. In addition, high blood pressure, atherosclerosis and other diseases may also lead to cerebral ischemia and hypoxia, triggering scalp pain on the top of the head.
4. Folliculitis: Bacterial infection of the hair follicles on the head causes local redness, swelling, tenderness, pressure pain, and manifests itself in the appearance of red pimples on the top of the head centered on the hair follicles.
5. Herpes zoster: caused by chickenpox-herpes zoster virus infection, mainly manifested as clusters of blisters of different sizes and obvious pain.

It is recommended that if physiological causes are ruled out, one should consult a doctor to clarify the cause of the disease and conduct appropriate examinations if necessary.
