Male patients with androgenetic alopecia are usually more likely to experience baldness at the age of 30-50. Male patients usually start to experience hair loss from the age of 20-30 years old, and the hair loss can be aggravated at the age of 30-40 years old, but based on the influence of personal constitution and genetic factors, for example, some patients have high work pressure and genetic factors, patients can develop baldness at the age of 40 years old, but there are also some patients who develop baldness only at the age of 50-60 years old. Now the patients who have been treated clinically, because during the treatment patients have been taking oral finasteride and topical minoxidil application, such drugs can inhibit the development of androgenic alopecia. This is why some patients do not necessarily experience baldness even at the age of 70-80. In addition, female patients with androgenetic alopecia have hair follicles that are less sensitive to androgens than men, so women generally do not experience baldness.
