Pulling Hair Out of Drains; Eating Drywall

28-year-old Evan has hidden a strange addiction from almost everyone he know, pulling hair from shower drains. In social situations, he heads straight to the bathroom and compulsively pulls hair out of the homeowner’s shower drain. For the past seven years, 26-year-old Nicole has been eating the drywall. She craves the taste and will eat up to three square feet of drywall every week.
