Research on tea tree oil use for specific conditions shows:

• Acne. Research suggests that a treatment gel containing tea tree oil might be effective at relieving acne.
• Dandruff. A tea tree oil shampoo used for four weeks has been shown to be effective at treating dandruff.
• Athlete’s foot. A tea tree oil cream, applied twice daily for one month, has been shown to be effective in relieving symptoms of athlete’s foot.
• Lice. When used in combination with lavender oil, tea tree oil has been shown to be effective at treating lice eggs.
• Nail fungus. Research hasn’t shown tea tree oil used in its pure form or in combination with other antifungal therapies to be effective in treating toenail fungus.
