Funny one! They call this the old man haircut or Benjamin Button Special. Russell Fredrick, co-owner of A-1 Kutz, a US-based barbing salon came up with the idea after efforts to make his 12 year-old son study and behave well in school proved abortive. 
The young dude’s behaviour and grades improved excellently weeks after he threatened to give him the “balding” haircut.‎ A mother brought his 10 year old son to the salon afterwards.
Fredrick told The Washington Post, “I hope that most people won’t have to do this unless it’s an extreme circumstance and nothing else works. There are a few people that are saying it’s emotional abuse; but on average, everyone is applauding the mother that brought the child in — and applauding me as well.”
