You don't see any lice or mites on her?
Could be she's just stressed or hormones. I'd think about giving her extra protein a few times a week - a little treat of egg, fish (sardines/mackerel/tuna) or meat. And I'd also try a little vitamin therapy for a several weeks to see if it helps. Give her 1/4 tablet B-Complex daily. See if the b vitamins make any difference at all.
