What does the Tea Tree oil do in FSG?

The tea tree oil adds scent, repels bugs, is antifungal (which helps preserve it longer), slightly moisturizing, and stimulates the scalp. I like to do a scalp massage once a week with 2 teaspoons evoo and 4 drops of tea tree essential oil. It brings more blood circultion to the scalp which stimulates hair growth, I also do not like the smell of plain FSG so I aded the tea tree, it just so happened that it had those benefits.
