I have build up, dandruff and itching. I am CG, but I shampoo with a sulfate free shampoo once every 2 - 3 weeks. As stated earlier I use the masque once a week as a prepoo/DC. It helps with itching and dandruff. I rinse it out, then co-wash with Tresemme Naturals Nourishing Moisture, it is also my leave-in.
