The vast majority of men’s hair loss is androgenetic alopecia, and there is no way to reverse it, but its progression can be slowed by oral and topical medications. Oral medications are the mainstay of treatment, and the first-line drug is finasteride, which can slow down hair loss and improve scalp coverage. Finasteride needs to be taken continuously for 6 to 12 months or more, and longer if the effect is to be maintained. The effect of hair regrowth will disappear within 6 to 9 months after discontinuation. Topical medications, mainly minoxidil, promote hair growth by increasing the duration of the anagen phase, shortening the resting phase, and enlarging and miniaturizing hair follicles, as well as inducing vascular endothelial growth factor, which helps to maintain the distribution of blood vessels in the dermal papilla. Minoxidil, like Finasteride, requires long-term use. Hair transplantation techniques are also one of the commonly used treatments for androgenetic alopecia. Men with significant hair loss need to be actively diagnosed and treated, and medications need to be applied appropriately and in accordance with medical advice.
