S.E.
There is a young tween model who is bald due to alopecia. I just saw her in some magazine but cannot remember what it was. She thinks bald is beautiful and is getting some recognition for standing up and out for herself. Maybe if you Google it you'll find something. Your friend's daughter might like to see a peer dealing with this so gracefully and powerfully.
My brother has a severe case of alopecia and has lost all hair on his body. It was hard for him in his 20s as he was very handsome and had gorgeous hair. But you're right, for a guy it's a little easier. I've had it very mildly since I was 21. What I understand of it and what I know for me personally is that it is directly related to stress levels, at least for my brother and myself. Things that have helped me are exercise, meditation (though I have a tough time with this!), acupuncture and journaling. It struck me when I was getting out of college and had to actually figure out what I was going to do with my life. It resurges when I'm out of whack a bit and feeling anxious about work, life, etc. Auto-immune illnesses can definitely be triggered by such things. For me, I feel there is a direct connection though this may not be the case for everyone. Is this girl feeling stressed about school, her social situation, something at home? Finding ways to help her de-stress and manage her feelings, feel empowered (journaling is a great and easy way to do both and good for a 12 year old as is exercise), know she can handle whatever changes are coming her way -- all this will hopefully help her condition, but even if not, it will make her happier and more secure in her life as it is. A win-win. I wish her the best of luck. It is a tough thing to go through. I hope she comes out of it more secure in herself and with all her hair back in place!
