Hot enough for ya? The NY Times has a cheap, easy solution for cooling off: the heat wave haircut! The paper calls summer "scalping season" and says that barbershops have been flooded as the temperatures have been rising -- with men shaving off their entire head of hair, beards included. They say "half measures are no longer sufficient" and the phrase "a little off the top" has gone out the window. One barber estimated that on a hot day 15 to 25 folks come in for the $14 "zero cut," which is pretty self-explanatory. Even women are joining in, as one shop noted the fairer sex had been coming in for a "Sinead O'Connor" to help them cope with the heat and humidity.
