D.S.
Hi, my name is D. and my son who is 14 has the same problem however he has been diagnosed with psoriasis.. he now has a lotion he must use as well a special shampoo..(T-Sal from Neutragena).. his spots have cleared up.. I think you should find a dermatologist and have them diagnose her.. it took many different doctors before my son was properly diagnosed.... good luck
