Solar protectivity of beards and moustaches, tested

parisiDr Alfio V Parisi [pictured here] and his team stuck beards and moustaches on some dummies, put them out in the hot, hot sun, and measured what happened. They did this after they had run a related experiment with toupees – a trial which itself was preceded by years of painstaking work with tree leaves, automobile windows, adolescent girls, lawn bowlers and snorkelers.

Parisi and his various collaborators have now published more than 150 scientific reports about what’s most dangerous – and what’s maybe a little less so – for people who expose themselves to daylight….
