Simplest and best "cure" for dandruff is to wash your hair less often. Shampoo removes all the oil from your scalp, respect your body it doesn't produce oil by mistake.
I wash hair once a week..can't go any longer than that...
Vianger goes on when I wake up...I just got home from work.
BTW ...I do agree with ughaibu...better for the hair to have natural oils, than loading up on products.
