Tightly curled scalp hair protected early humans from the sun's radiative heat, allowing their brains to grow to sizes comparable to those of modern humans. Loughborough University researchers in the UK worked with Penn State University to study heat transfer through human hair wigs and the environment to examine how diverse hair textures affect heat gain from solar radiation.
