hormones stop hair falling out during pregnancy, so as the hormones settle down, all the hair that should of fallen out if she wasnt pregnant will fall out. it will settle down as the hormones return to normal, and unfortunately, there is no miracle cure.. she should brush her hair gently and only when necessary, and try not to worry as this wont help matters. she may benefit from regaine for women, but continual use is required, stopping the treatment will thin the hair again, plus it does not work for everyone, hope this helps, x
