Pattern hair loss is classified as a form of non-scarring hair loss. The Hamilton–Norwood scale has been developed to grade androgenic alopecia in males. Female-pattern hair loss more often causes diffuse thinning without hairline recession; similar to its male counterpart, female androgenic alopecia rarely leads to total hair loss. The Ludwig scale grades severity of female-pattern hair loss. Research indicates that the initial programming of pilosebaceous units of hair follicles begins "in utero". The physiology is primarily androgenic, with dihydrotestosterone (DHT) being the major contributor at the dermal papillae. Men with premature androgenic alopecia tend to have lower than normal values of sex
Hamilton Anxiety Rating Scale and new research has had an effect on the scale's perceived usefulness. As a result, there have been changes, and challenges, to the original version of the scale over time. In 1959, Max R Hamilton developed the first version of the Hamilton Anxiety Rating Scale. He included a distinction "between anxiety as a normal reaction to danger, anxiety as a pathological condition not related to stress, and anxiety as a state or broad syndrome that he termed "anxiety neurosis.'" Hamilton developed the scale to be used with patients already known to suffer from anxiety neurosis, not to be used as
