i don't really have any thoughts on the photos above--i'm all for free expression of whatever one feels inclined to do, for the most part.
and, i don't really have any opinions about women's hair, in general. i like mine long, but have always wished i had the nerve for short hair. however, it's also not very practical for my curly hair, either.
instead, i wear it long and donate a section of it to locks of love about every 18 months, and then grow it out and do it all over again. even though my hair isn't too far from my waist, because it's very curly, it's length appears more like the middle of my back.
for men, i guess i'm simple in my tastes--whatever looks good.
some men look great with it very, very short. i think that can be very attractive. on the other hand, short on the sides, and longer on top can be great too.
i'm just not attracted to the ponytail thing, personally. and the mullet? no...just no.
