Ferriman and Gallwey [33] published a hirsutism rating scale that is illustrated in the table below. This scale allows the physician to measure a response to therapy objectively. This system is the most widely used and evaluates body areas for absent-to-severe hirsutism with scores of 0-4, respectively. Scores of 8 and higher are consistent with a diagnosis of hirsutism. This scale does not measure the thickness of the hair, which is another way of objectively assessing excess hair.

Scoring systems are a useful aid in quantifying hirsutism and in evaluating treatment response. However, they are somewhat subjective, so the absolute score is not used to define hirsutism. Even with scores >8, the patient determines if she is hirsute. When evaluating treatment response, the patient can determine if he or she notices a difference. Photographs are helpful for documentation and for following the progress of therapy.
