My hair reaches down to about my nipples, or the bottom of my shoulder blades. But it curls up so it stays at shoulder length....
And I must say it is awesome, you cannot beat the feeling of getting recognized as "That kid with the awesome hair", putting it a ponytail makes you feel like a god and chicks always want to do something to it(Straiten it, dye it, plat it ect.).
Although I do get alot of flak because of it, but if you keep it up and go through that it shows your steely resolve.
:Anyone thinking of doing it seriously should, you do need to style it when it's in the 'shit' stage so as not to look retarded.
