HSM and Hats

[emtp]

I wear a HSM, if your worried about messed up hair cut it short, if you wear your hair longer wear a hat and mask, with the foul tips I've been hit with wearing both the mask and HSM, never going back to the mask, our area has no preferance on hat or not but only a couple of us wear the HSM. I'm still relatively new, umping 5 years, is there a giudeline some where for the hat no hat and does it address the HSM or do they allow personal preferance? Thanks in advance for any help.
