I suffer from dry scalp but have greasy hair. Does the Dry Scalp Shampoo tend to make hair more greasy?
That is an unusual combination. Usually the oiliness from your scalp should prevent dryness. I suspect that the dryness is actually either a chemical intolerance in which case the dry scalp shampoo should be excellent or a yeast or fungus based infection of your scalp. In which case the Oregon shampoo would be better as it contains an anti-dandruff ingredient. Both are moisturising and are not designed for greasy hair but more aimed at dry hair. In this instance, I would recommend asking a doctor to look at your scalp and check the cause of the dryness.
