Wikipedia item mentions how the study of UV on sports resulted in creating Tanning Parlors
While studying the beneficial effects of ultraviolet light on athletes, German scientist Friedrich Wolff noticed an interesting side effect - tanned skin.
Realizing the appeal of a beautiful tan, Wolff founded the indoor tanning industry.
His research led to development of indoor tanning equipment and lamp technology.
Happened to notice many professional black athletes had shaven heads or very short hair
Most likely that they have short hair due to being easier to move around quickly on the basketball court
However, if that were the only reason, the white players would also have very short hair, and they do not seem to.
