Martin Davis, USA
I have strong feelings about hair, but mostly not about my own. I love hair on women especially if it is long. (My mother wore her hair long when I was a baby.) I love all of their hair; I don't like the American custom of shaving armpits, and I could never relate to the fetish of shaved pubic hair.
I've always had curly hair ("Jewish afro"). When I was a graduate student at Princeton I was induced by social pressure to get a crew cut. But when the sixties came, I let it all hang out, and only had my hair cut when it had become really hard to manage; usually in the late spring.
I have no particular feelings about the act of having my hair cut as long as itchy hairs don't get down my shirt.
And losing hair has never been a problem for me.
