Seventy years young seems to reduce sweat problems, actually.

I don't get a "hot" head as such, but sure sweat a lot on my head. When it's warmer, I carry a washcloth along to wipe sweat off with. They make a little sweatcatcher gutter thingy, not sure what it's called, that goes across your forehead, but I haven't tried it.
