Diagnosis
Typical male pattern baldness is usually diagnosed based on the appearance and pattern of the hair loss, along with a detailed medical history, including questions about the prevalence of hair loss in your family. An experienced medical hair loss expert should examine the scalp under magnification (preferably with a device called a densitometer), in order to assess the degree of miniaturization of the hair follicles. This assessment is very important when recommending the proper course of treatment.
