What few I have!
This thread has evolved to include hair on other parts of the body. No one, as far as I can read, has mentioned ear hair! Should ear hair be shaved off??? There's some people with some pretty long strands of ear hair growing from either within the ear or from the earlobes themselves. And, many times, those ear hairs are gray!!!
And then there's nose hair!!! They can get long too!

(A mustache, by the way, can "hide" long nose hair as they both grow and mingle together!)
Hair! Got to love it!
Cheers!

P. S. Oh yea. I voted that the tee-shirt need not be required. Honestly? I think it looks dorky when either a man or woman wears a tee-shirt underneath their scrub top. Just my 2 cents worth!
