Tea Tree Oil by New York Biology

I have been using tea tree oil for the last year or so. I have have dry scalp issues and dandruff shampoos really work as much as I need it to work. I started to use my regular dandruff shampoo and then add 4 or 5 drops of tea tree oil to the conditioner. I wash my hair, use my tea tree added conditioner then let it sit as I wash my body. The tea tree oil feels nice and tingly on my scalp. Tea tree oil can also be used as an antifungal, decongestant and also to help for acne. I am really happy with this tea tree oil by New York Biology. I like that it lists the percentage of Terpinen-4-ol (45%), which is the active ingredient in the melaleuca plant where tea tree come from. Also come in a dark amber colored bottle which keeps the oil from getting light and going bad. I received this item in exchange for my honest, unbiased review.
