Question: how often should you use tea tree oil on your hair?
Answer: To help with dandruff, apply a shampoo with 5 percent tea tree oil to your scalp. Lather for 3 minutes daily for 4 weeks. For healthy hair, dilute tea tree oil with a 1 to 10 ratio of tea tree oil to almond oil or another similar oil. Use the mixture every day to get the best results.
