Hair loss is often categorized into physiological hair loss and pathological hair loss. Physiological hair loss can be adjusted through diet and sleep. Pathological alopecia can be seen in baldness, seborrheic alopecia, androgenetic alopecia, fungal infections and so on, which can be improved through medication. 1. Physiological alopecia: physiological alopecia may be caused by overeating, over-nighting or mental stress, so patients can improve their diet, sleep and mood. 2. Pathological alopecia: For patients with baldness, glucocorticoids, such as compound betamethasone, can be used locally to improve the treatment. For patients with tinea capitis, ketoconazole lotion can be used externally to improve. For patients with seborrheic alopecia, oral vitamin B6 can be taken to regulate the secretion of oil. Androgenetic alopecia can be treated with topical minoxidil and oral finasteride or spironolactone if necessary. For patients with more serious hair loss, it is recommended to go to the hospital in time for examination and symptomatic treatment under the guidance of the doctor. All of the above medications should be used under the guidance of a doctor, avoid self-medication.
