Early 2012, she used this certain anti-dandruff shampoo and it worked well, but after a few months of using it, the
dandruff came back and seemed to have become stubborn. Now,
no matter what kind of anti-dandruff shampoo she uses, it won't disappear.
She used to have thick hair, now it seemed to have thinned a bit, as well, because of hairfall which may be related to it.
Any advice??
