Quick Tip

The first extraction of tea tree oil was from the plant Melaleuca alternifolia, and this species of plant native to Australia remains the most important for commercial extraction.

What Does Research Say?

Does tea tree oil kill lice? Yes, according to a 2012 study, tea tree oil may help kill lice in the nymph and adult stages of their life (1). Tea tree oil treatments may also keep the lice eggs from hatching.

Another 2010 study showed promising results while using tea tree oil for treating lice (2). In the study, researchers used three types of treatments to treat children with head lice. One of the treatments contained a mix of essential oils like tea tree and lavender oils, which showed the greatest benefit to those with head lice.

In another study, researchers compared certain botanical and synthetic substances that can be used to prevent lice in kids (3). Tea tree oil was the most effective treatment of all. This oil, when used with peppermint, could also help repel lice. However, the long-term use of tea tree oil for removing head lice is yet to be studied.

Side Effects Of Tea Tree Oil

• Tea tree oil may cause skin irritation and allergies in a few people. It has been identified as a contact allergen (6).

Apply a small amount of diluted oil to a small area of your skin and watch for any reactions over the next 24 hours.

• There is no evidence stating that tea tree oil is safe for pregnant and breastfeeding women. Hence, stay safe and avoid use.
