Interesting theory, but just from my own anecdotal evidence I think it's er...shaky, to say the least. I just cut my hair way short, and am thinking of cutting it even shorter. Yet I'm in a stable relationship, and have recently experienced a surge of intimacy and lust for Ratbastid that is unparallelled in our 12 years together. I'd tend to go more with what antifishstick says - it's less about relationships and men than simply about change. And for me it was at least to some extent about practicality - I was just getting damn sick of taking care of even chin-length hair. All the blowdrying and fussing and brushing. Much easier to wake up and get my hair wet and call it good. Funny. You men always think it's all about you
