Going bald at 22? (pics included)

[iDontWannaGoBald95]

My hair is falling out an alarming rate. I'll lose about 50 strands during a shower, and around 20 strands styling. Even just gently stroking my fingers through my hair will cause some hair to fall out.

Additionally, I am also losing a lot of pubic hair as well. They fall out very easily during a shower, for example. Could losing head hair and pubic hair simultaneously be related?

Should I get on finasteride? How would I go about getting it? I'm located in Canada, if that is of assistance.

Thanks for reading and any help will be much appreciated.
