James Hamilton — طبيب في كولومبيا

James Hamilton is referenced on clinic educational materials as the developer of the Norwood–Hamilton scale in 1951, with later revision by O’Tar Norwood in 1975. The clinic describes the Norwood–Hamilton classification as a visual system with seven main types of male hair loss, used to standardize communication between specialists and patients. It also highlights the scale’s role in prognosis and treatment planning—helping determine suitability for medical treatments such as Minoxidil (as mentioned in the clinic’s educational list).
