Hmm, that is surprising. It’s long been known that perfectly smooth things are less aerodynamic than dimpled/rough surfaces. Maybe the “rough” nature of skin (dimples, creases, hair follicles etc) is enough to trigger the optimum boundary layer that sticks to the leg, and hair causes too much turbulence.It’d be interesting to see some imaging of the fluid flow around the leg.
I have read previously somewhere that in terms of aerodynamics it would be best to leave a 10-15m strip of hair down the centre of the leg/shin to best aid airflow...?
