I know a couple people who were born with Alopecia and it is a dreadful thing to have.
Especially difficult in the sunshine. They 'burn' very easily and have to always be covered from head to toe.
The St. Louis Zoo used to have a chimpanzee with Alopecia and it was a weird sight. A chinp with absolutely no hair on its body!
This young woman is doing a great service in bringing this affliction to the public eye!
