Hey I have a bit of an afro...just a bit too long now, so it falls and i have a fro that only extends sidewards, not up!

I'm 19 and have absolutely no grey hairs that I could find...

But I have a mat who is 22 and is completely grey...and another who is 20 and wont have any hair at all in about a year (its not receding yet, just very fine, and we give him trouble)
