It helps grow your hair, prevents you from having dry scalp also
It also adds moisture and hydration. 
Tea tree oil is great for itchy, dry scalps, and is known for its anti-fungal properties. All you have to do is rub a dab of it into your scalp with the ends of your fingers and massage it. A lot of brands are recognizing the benefits of tea tree oil so they're adding it to products. So if you don't want to use plain old tea tree oil you can buy products with it in them.
