I would take her to see a dermotologist. I have alopecia areata and it started that way too. It's not as scary as it sounds but it does mean that hair falls out in round patches and then grows back. Technically it's an immune system problem where the body attacks the hair follicle thinking it is bad. I was diagnosed with this at age 4 and my parents first thought I was pulling it out. I am now 32 and still have it. Some periods are worse than others. If this turns out to be what she has, feel free to contact me for additional info.advice.
