Anyone have hair loss from wearing the headgear?

Hello! I know this may sound stupid but I am trying to get to the bottom of my hair loss. In the last month or so I have started loosing gobs of hair and I don't know why. At first I thought it was from a change in medicine so I quit taking it about 2 or 3 wks ago but I still am loosing my hair. So I got to thinking about the headgear that I wear and wondered if that could be the cause....has anyone started loosing hair as a result of wearing the headgear? I have long hair so usually I will put it in a ponytail before I put my gear on. I know that some men loose their hair when they wear hats all the time so I wondered about this. Thanks in advance for your input! Kellie
