IMO, short hair is an extremely disturbing trend in metal. If it weren't for the piercings and the tats, it would be nearly impossible to tell the musicians from the serial killers. I vote with the masses -- dig your heels in and hang on with every bit of stubbornness you've ever mustered.
Just looking at that pic makes me nervous, because most of the men in my family have gone bald, so ther's a very good chance its in the cards for me as well....
there are pills you can use to stop losing your hair, just ask your doctor. They work on 99% of people. Secondary effect: on 1% of people, they lose their sexual appetite (and sometimes their boobs grow)
