Dandruff may be caused by an overgrowth of yeast on the scalp. Tea tree oil has antiseptic properties that can neutralize that yeast, doing away with the dandruff. But it can be harsh, so here’s how to use it…

Add five drops of tea tree oil (available at health-food stores) to your regular amount of shampoo—but not dandruff shampoo. (Dandruff shampoo may actually remove protective oils from your hair and skin.) Wash your hair as you normally would, and be sure to rinse thoroughly. Some prepared shampoos made with tea tree oil are also available.

Note: Tea tree oil has a pungent antiseptic scent that may take some getting used to. When you open the bottle and take your first whiff, keep in mind that it will be diluted in your pleasant-smelling shampoo.
