I do not think it has anything to do with fertility and health, haha. Hair is dead cells like fingernails and dead skin. I have known health nuts with short hair and drug addicts with super long hair, so a clue to someones health and fertility, I think not. My boyfriend has very long hair, rocker look, and I have a cute chin lenth bob which is very fashion forward right now. Hair has nothing to do with gender roles or attractivness. There are hot guys with long and short, and hot women with long and short hair. Short hair is more edgy, and long hair is often plain Jane, not "different" depending on how you style it. Edgy, modern, rocker chicks look hot with a ( good style ) shorter hair cut and many guys find it extreamly HOT! It's all about how your style compliments your face, male and female. All face shapes look different with different styles, not all faces are flattering with long, or short, and trust me, it's All About the Cut. You wanna be hot? Go see a good Hair Dresser! They will know what will flatter your particular face shape and give you a great cut accordingly, if it makes you look less hot, then don't see them again. My best advice, before taking drastic measures with your hair, do some research and if you see a girlfriend with a super cute cut that makes her look smokin', ask her where she got it done and the phone #... but on the other hand, a guy who would dump a woman over something as superficial as hair, is not a keeper, nor in love, maybe they have some odd hair fetish. My man would be by my side and tell me I was beautiful if I had chemotherapy and went completely bald. No worries honey. Ur not missing anything with that loser. Take a deep sigh of relief that he showed his true colors and left before y'all had kids and you were stuck with a caveman. " me woman have long hair to drag her around, oaf oaf!"
