A common condition causing hair loss on the crown of the head is androgenetic baldness, which can be treated in men with the application of minoxidil preparations and oral finasteride. For female patients, topical application of minoxidil preparations is preferred, and oral anti-androgen drugs such as spironolactone can be taken if treatment is not effective or if there is hyperandrogenemia. Medication can be combined with low-energy laser treatment and autologous hair transplantation.
