I Have a Question

Today my sister got an unexpected headshave because of her mistake but she got it smooth because our mom said that now you have just 8mm hair so it is good to ahave it smooth it will take only 2 weeks to grow like 8mm again she denied but we convince her. she had hip lenght hair and now she is not happy with her smooth shinny bald head
I like to know what will you do get an unexpected heaadshave ?
