Hormones can treat hair loss. Hormones are used to treat some patients with hair loss. There is a clinical type of hair loss called androgenetic alopecia, and for male patients with androgenetic alopecia, finasteride can be applied orally for treatment. For female patients with androgenetic alopecia, treatments such as spironolactone or cyproterone can be considered. There are many other clinical patients with hair loss that is not due to altered hormone levels, for which these drugs are not suitable. Some patients have alopecia areata due to emotional depression. For the treatment of alopecia areata, you can consider applying traditional Chinese medicine, or topical application of minoxidil, or lifestyle adjustment, or psychological counseling to treat the condition. Therefore, if hair loss occurs, patients must choose the appropriate treatment under the guidance of a doctor, and should not treat themselves with random medication.
