I remember the moment
that I discovered the small bald
patch on the back of my head. My sister was straightening my
hair when she announced that
there was something I should
see. It was a tiny patch,
curiously smooth and strangely
comforting to touch. I thought nothing of it. But within a
month it had grown from the
size of a five pence piece to
that of a ten pound note, and
within two months I had lost
half of my hair. What do i do

You might need to see a doctor, the only thing that comes to mind right now is a condition called alopecia, where all of the hair falls off.

I hope it's not sha, but it's something worth checking out

Of course women go bald, are they not humans too? If you're a female you can take solace in the fact you can wear weaves and wigs to cover it up.
