Tea tree oil can be used to treat a multitude of skin disorders, so it is no surprise that it can be used to stimulate hair growth. Tea tree oil unclogs hair follicles thus stimulating hair growth.
Despite its name, using tea tree oil on the scalp won't leave your hair greasy. It will, however, clean the scalp and help to eliminate dandruff.
Tea tree oil is also known as melaleuca oil and can be purchased in a variety of ways. 100 percent pure tea tree oil can be purchased as well as tea tree blended with other essential oils or tea tree oil as an ingredient in shampoos, soaps and body washes.
Tea tree oil will stimulate hair growth not only by increasing the health of hair follicles but also because tea tree oil boosts overall health and immune system stimulation through its aromatherapeutic values.
Cajeput and Niaouli essential oil are more intense versions of tea tree oil but can be used in the same way to stimulate hair growth.
Tea tree oil should not be ingested or used on mucus membranes. Tea tree oil should always be diluted until you've tested your skin for sensitivity, though it can be used full strength in small amounts; 20 percent concentration in a carrier oil (coconut, jojoba, olive) is a safe place to start.
