Seborrheic alopecia can be treated by taking Finasteride, but the medication should be used as prescribed by the doctor. Seborrheic alopecia is a kind of progressive hair loss, common in young men, mainly related to genetic factors and androgen metabolism abnormalities and other factors. Seborrheic alopecia can be treated with finasteride, which can reduce the level of dihydrotestosterone in the blood and tissues, thus effectively relieving the symptoms. However, the side effects are loss of libido, headache, dyspnea, etc. It is prohibited for those who are allergic. In addition, patients can also use topical minoxidil, which can stimulate the proliferation/differentiation of hair follicle epithelial cells and carry out effective relief of hair loss. Spironolactone can also be taken orally, which can bind with androgen receptor and inhibit androgen secretion, thus effectively reducing hair loss. Overwhelming hair loss can be treated by taking Finasteride, but it should be used under the guidance of a doctor after a hospital visit.
