Dandruff is the shedding of dead skin cells from the scalp. Dandruff can be caused by chronic pain or either by irritations or itchy skin.
It's important to point out that stress can provoke dandruff formation more quickly and in greater amount, and people with oily hair are more likely to have dandruff. Anti-dandruff shampoo and treatments are created to stop dead skin appearance. That is why they intend to remove oil excess from the hair and reduce sensitivity of the area to avoid dandruff production or reduce it until removing irritations.
Likewise, they eliminate oleic acid. Anti-dandruff shampoos are applied just like any other shampoo, that is, during the shower. It’s recommended to wash vigorously reaching all areas. In this regard, the time they take to make an effect is short. However, those with a serious dandruff problem may need to apply more than once a day.
