Sean- if i understand, you are less affected by the heat because your acclimated? Personally, I loved having the long hair and eventually dreds, but couldn't handle the summers. One day i just walked into a barber and went for a #2 razor cut. Almost three feet of hair/dreds to the floor. People were watching me get this cut like it was a spectacle. For years I wore it short. Just this fall, decided to go long again. Its now about short shoulder length. In the back of my head, I know i will cut it the first 95 deg day.
I would think so, but the climate is changing and as such the summers are getting hotter. That said i must say that i only hear the ladies complain about the heat and their long hair, not the rastas (rastafarians-true followers of the religion). But you do find the ladies cutting their hair because of the heat, how often they have to go to the hairdresser, the length of time for processing etc. They cut all off and voila! no hairdresser, no setters, no hairdryer, just wash, rinse and you're good to go
