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.
This chart of hair loss pictures is a useful tool for diagnosis (and to avoid misdiagnosis) and for describing the extent of hair loss for treatment purposes. There may be times you will have to relay this information via telephone or the Internet to physicians or practitioners from whom you are seeking information. Note that there are many variants in pattern hair loss; the images on the Norwood Scale have been cited as the most typical.
