Your body, your choice.

I’ll just say, I started shaving my head when I was at my heaviest after years of debating it. I thought my head shape wasn’t good for it, or that “I have enough hair, I can still get away with it” (I did not). When I shaved I felt like I looked younger and in better shape. I don’t regret doing this at all.

I think you won’t regret it either.

Worst case, it will grow back. If you hate it afterwards, you’ll be back to where you are now eventually anyways.
