I assume that your daughter's problem is on her scalp. There are stronger anti-seborrhea preparations, but if fungus is still a live possibility, you ought to wait till the culture is back, because if it's positive then obviously the treatment would be different.
Telogen effluvium generally slows down after 4-6 months, after which the hair grows back. So I think you're OK. You'll need to check with your dermatologist, however, to be sure that no other diagnoses are worth considering, but based on the little information you've given me, telogen effluvium--which can be quite dramatic and scary in the short term--does seem most likely, and that is reversible over the next 6-8 months.
Take care.
