Hair shark 

small lock or locks of hair sticking up on the top of your head when it's in a ponytail - like shark fins sticking up out the water

I thought I had pulled my hair back into a neat ponytail, but found out when I looked in the mirror that I had like 5 hair sharks.

Hair share 

When one person, usually with short hair or no hair, drapes the hair of another person, who has long hair, over their own head in a kind of Bobby Charlton comb-over by proxy. This can give the follically challenged the illusion of hirsuteness, even if it is only temporary.

Hey Fred, Tinas coming over, quick lets hair share so she doesn't notice I'm as bald as a coot.

sharhairer 

a person who tells their whole life stories in the most inappropiate places, ie the bank, post office or the line at the DMV. Can make ones hair stand on end.
Shanahair is a very regional definition, used espescially for weird info.

That girl just told the bank teller that she had a wart removed from her ass, what a sharhairer.
