My Mom shaved my head for getting bad grades on my final report card, was this an okay punishment?

When I got a D in one of my classes on my last report card, my Mom shaved my head with an electric razor and then with shaving cream and a razor. My Mom said this is the punishment I get because she thinks the reason I got a D is because I am always worrying about my hair and less about my grades. I feel absolutely humiliated, especially since I am a girl. Was think an okay punishment?
