Right shape of head? Who doesn't?
This "hair' business? Tell me what that's all about.
Oh, it's "Well, I used to have hair, and now it's going away." And so? Getting older is something no one can avoid (this side of the grave).
Don't obsess. Shave it or cultivate what you have left. I take off what I've got, or I let what I've got grow out depending on my mood. No one much cares one way or the other. Why should you?
