Mom won’t let me shave my head...

I really want to do it. I’m tempted to. But if I do I’d be kicked out of my house. It’s a huge over kill for something that could grow back just like that. She tells me if look like a man and that I’d become ugly. But I find it so empowering when I see a woman shave her head and I think my head is beautiful. Not only that but when I asked other people if I’d look good with a buzz they all reply joyfully and supporting lovingly.

I know “mother knows best” but...is there any advice on trying to convince her...?
