It seems all that leaning in we do to get up close with friends for the perfect selfie could provide the perfect opportunity for sharing lice.
Mary McQuillan from head lice treatment center NItless Noggins explained to SFist, "I've seen a huge increase of lice in teens this year. Typically it's younger children I treat, because they're at higher risk for head-to-head contact. But now, teens are sticking their heads together every day to take cell phone pictures."
She warned, "Selfies are fun, but the consequences are real."
Before you ban all selfies, however, it seems the lice warning isn't all it's cracked up to be, as a professor at the Harvard School of Public Health told NBC News it's probably not a real concern.
Dr. Richard J. Pollack explained, "This is a marketing ploy, pure and simple. Wherever these louse salons open a new branch, there always seems to be an epidemic. It's good for business."
Back to your selfies...
