A mom named Christin Johnson posted to Facebook earlier in February about what happened when she dropped her daughter off at her ex-husband's house. She'd gotten her teen daughter highlights in her hair for her birthday. It's not clear if this is something her father had warned her not to do, or if he flew randomly off the handle, but when Johnson went to pick her daughter up, all of her hair had been cut off.
The cut was allegedly something Kelsey was forced to do by her father and his new wife. While not everyone may consider haircutting physical abuse, Kelsey's dad did take away her personal autonomy by cutting her hair, in an attempt to shame and humiliate her. In my opinion, it's really messed up.
