Weirdly-interesting study I came across:

Background: The Ferriman-Gallwey hirsutism score is the currently accepted standard for assessing excess hair growth that may indicate hyperandrogenicity. The score was originally based on 60 Caucasian women, and recent studies suggest that it may need modification to be used in other populations. Objectives: To investigate ethnic, racial, and pigmentary variations in hair growth of the upper lip in diverse multinational populations. Results: Variations in hair growth of the upper lip were significantly related to self-reported ethnicity and race. In a logistic regression with racial groups and skin lightness, all racial groupings (African American, Hispanic, Asian Indian, and East Asian) were predictive of hair growth (all p<0.0001), but skin lightness was not (all p>0.05). Conclusion: The observed differences in constitutive hair growth illustrate the need to develop an ethnically stratified visual scoring method to more accurately characterize the severity of excess hair growth.

Hirsutism is characterized by excessive terminal hair growth in a characteristically male pattern and can be a cutaneous manifestation of hyperandrogenism [sic] (Male hormones in female body).

There were significant racial differences in hair growth and color of the upper lip, with Indian women having more hair growth than any other race (all p<0.01) and Caucasian women having less than any other race (all p<0.009) ( Figure 1). When analyzed by ethnicity, Japanese women had significantly less hair growth than East Asian American women (x=41, p<0.001), and Caucasian Italian women had significantly more hair growth than Caucasian British or American women (x=35, 21, p<0.0001, respectively). Hair growth of the upper lip was related to skin lightness (L*-value). Those with hair growth had darker skin of the forehead (t=7.6, p=0.0000), cheek (t=4.9, p<0.00001), and inner arm (t=3.1, p=0.002). In a logistic regression with racial groups and skin lightness, all racial groupings (African American, Hispanic, Asian Indian, and East Asian) were predictive of hair growth (all p<0.0001), but skin lightness was not (all p>0.05).


*Relevant to chart below: Scoring of the upper lip was done according to the method of Ferriman-Gallwey (mFG scoring)4; a grade of 0 indicated no hair; 1, a few hairs at the outer margin; 2, a small moustache at the outer edge of the lip; 3, a moustache extending halfway from the outer margin of the lip; and 4, a moustache extending to the midline of the lip (Table 1).
