The invention discloses application of a semen nigellae extract in preparation of a product for preventing and / or treating androgenetic alopecia. The total content of nigella alkaloid and nigella alkaloid 4-O-sulfite in the nigella seed extract is not less than 2%. The preparation process comprises the following steps: degreasing nigellum nigrum medicinal material powder with petroleum ether, extracting with an acidic aqueous solution, and enriching with macroporous adsorption resin and specifically purifying with anion exchange resin in sequence. Experiments show that the extract can most significantly reduce the levels of testosterone (T), dihydrotestosterone (DHT) and creatinine (Cr) in an androgenetic alopecia model mouse body, increase the level of estradiol (E2) and effectively promote back hair regeneration, and the effect of the extract is significantly superior to that of a water extract, an alcohol extract and a positive control drug. The extract is clear in component and controllable in quality, can be used for preparing medicines or wash supplies with multi-target anti-hair loss and hair growth functions, and provides a novel efficient natural raw material for treating androgenetic alopecia.
