My niece was just diagnosed with alopecia. It is a hair condition where the hair wont grow. She had hair it wasn't thick it was barely anything , but then at 3 last year she lost it all. And she also just recently lost her eyebrows and eyelashes. she is 4 now. And there is'nt anything really to do about it. There is med. but she just got worse. At least its not her health and as long as she is loved and very very spoiled as she is, she'll be fine. It might be worth asking the doctor. She went to children's hospital in philadephia.
