I have a dear friend whose 12 year old granddaughter has lost every bit of her hair. Her hair was gorgeous, long, brown, and shiny. Then it began to fall out in clumps, until now she is bald. The doctor diagnosed her with alopecia, but something doesn’t feel right about that to me. Why would this happen to such a young person. She’s a dear, sweet, girl, very conscientious and respectful. Can anyone tell me anything about this?
