What to Leave Out
One of the most important steps in oily hair prevention is what you should leave out. Corbett advises skipping conditioner at all costs, "unless you have very long hair and need a pinch on the ends only!" he says.
If your hair is fine, or you can brush it out easily after showering, then you probably can do without conditioner. However, if you find that your hair is still rather unmanageable and could use some extra moisture, try Jason Natural Cosmetics Tea Tree Oil & Scalp Therapy Conditioner. Because it's made with tea tree oil, a natural oil absorber, it's your best bet for grease control.
