As we all know, teachers play a big part in shaping the minds of young children - but this inspirational teacher made sure to educate his pupils in matters of the heart as well.
"Mahan had become isolated after going bald [and the] smile had disappeared from his face"
When Ali Mohammadian realised one of his pupils, who is believed to have lost his hair to cancer, was being bullied for being bald, he decided to shave his own head in a heartwarming gesture of support.
He posted a photo of himself with his newly shaved head, alongside the little boy and his classmates, on Facebook.
Writing on the social network, Ali explained: "Our heads are sensitive to hair.
"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."
The effect of his kindness has been extraordinary; the image has been shared hundreds of times and the teacher has been named "hero of the week" by popular Iranian TV show Paysh.
Speaking with The Guardian, Ali said: "I'm so happy that this has touched many hearts and people reacted enormously positive.
"Everyone in the school now wants to shave their head."
If they do they will be in good company; Mohammadian also revealed that his 23 other students were so inspired by their teacher's actions that they also shaved their heads.
"This Saturday morning I stepped into the class and everyone had gone bald"
"I told them to wait until the winter's cold weather was over but when we came back from Tehran, they had all shaved.
"This Saturday morning I stepped into the class and everyone had gone bald."
What an inspirational man. It's amazing to hear that this man has helped change the perspective of his pupils and, with one simple gesture, transformed bullies into supporters - if only all children were so lucky to have such an inspirational teacher!
