Why do you think hair fetish isn't as popular or mainstream as fetihses for asses, feet, breasts, etc.?

You may disagree with me on this, but let's face it, our fetish for hair isn't exactly as well known as fetishes for the aforementioned body parts. I mean we're kind of a rare breed, don't you think? I'm not saying we should be ashamed or embarrassed about our love for long hair. On the contrary, it's great we can desire and appreciate things most guys and girls don't usually appreciate on a woman's body. But I can't help wonder why having a fetish for hair isn't more well known. Or better yet, I can't help wonder why it's not more accepted or popular. I mean you won't find many who don't like long hair. And I'm sure we all secretly desire hair in some way. It's just weird how something we all like isn't more common as fetishes for other body parts.
