Earlier this month, Mohammadian posted a picture of himself with eight-year-old Mahan Rahimi on Facebook. "Our heads are sensitive to hair," he wrote on the social network in support of his student. "Mahan had become isolated after going bald, smile had disappeared from his face and I was concerned about his class performance. That's why I thought about shaving my head to get him back on track."Mohammadian's Facebook post soon caught the eyes of hundreds of Iranian web users. "When I logged in to my Facebook the next day, I couldn't believe the number of people who had liked it and shared it," he said.
