An editorial in the July 2014 issue of JAMA Pediatrics (the Journal of the American Medical Association) touts the photoprotective effect of the bowl cut and bangs that sweep across the forehead, arguing young boys sporting this hairstyle to look more like Bieber seem to develop fewer freckles on the forehead — signs of skin damage and a risk factor for skin cancer.
"For the past few years, we have embraced this hairstyle in our teenage patient population to encourage discussion of sun protective measures," write Crystal Agi and Bernard Cohen, doctors at Johns Hopkins Hospital."It is believed that the majority of an individual’s lifetime sun exposure occurs during childhood and adolescence, making diligent sun protection during these years critical."
The best part: The doctors are billing this outlook as the new "Big Bang Theory."
