Hair loss on the head makes me think of demodex (just one of a ton of possibilities), an infection (but less likely if you haven't put her hair up lately), ringworm, or a slight chance that there is a hormonal problem..
If it came out all at once and you didn't see it happen, I suppose she could have ripped it out on accident.
