Tea Tree Oil: Because tea tree oil has antiseptic properties, it can help fight off any bacteria or fungus that may be contributing to your dry scalp. Tea tree oil also has moisturizing effects, which can help soothe your dry scalp. To use tea tree oil, try adding a few drops to your shampoo or apply it to your scalp with a carrier oil as a bedtime scalp mask (rinsing it off in the morning).
