Mom shaves daughter's head as punishment

This video of a mom punishing her daughter has gone viral! 

Allegedly, her daughter bullied a bald cancer patient at school and she took a video of her shaving her daughter's hair off to teach her a lesson. 

In the video, you can see lumps of brunette hair hit the floor, and a young girl wailing and covering her eyes while the older woman shaves her hair off. 

Is this a fitting punishment?
