Welcome to the SBG Family JJ,
You've already recieved lots of great advise, and to me it sounds like you are ready to take the plunge, you just need that little tiny bit extra somthing to make you realize that this is the right move for you. Let me just say to you that if you are at all self conscious about your hair loss, then people around you will pick up on that negativity (they may or may not know what the cause is) but they can pick up on negative attitudes. So as many people here on this forum have pointed out that after they have decided to finnaly get rid of the burden of trying to cover it up, or wonder to themself "does he/she notice my thinning hair?" They have found a new and big boost to their self confidence, and being confident in yourself and happy with yourself, will definatly show and rub off on others.
