Tea tree oil works to treat cases of head lice by suffocating the live bugs. If you want to use tea tree oil for lice, keep in mind that a little goes a long way as essential oils are concentrated and potent. A tea tree oil lice treatment consists of a carrier oil, like olive oil, with just a few drops of tea tree oil added to the mix. Note we do NOT recommend tea tree oil due to possible allergic reactions. If you still decide to use tea tree oil below is how it is used:

How to treat lice with tea tree oil:

Step 1: After you have created your mixture of tea tree oil and your chosen carrier oil, saturate the head with the mixture.

Step 2: Using a good professional grade nit comb, section the hair and comb them out until you are no longer combing out bugs or lice eggs. To eradicate a case of lice, you have to pull out all of the nits. Skipping this crucial step and leaving nits in the hair is a recipe for the lice hatching from these nits and the case continuing.

Step 3: Apply more of your mixture to the hair to ensure every strand of hair is saturated. Leave this on the hair for 8 hours.

Step 4: Have a follow up plan ready. Eggs laid the same day or day before treatment are not visible, so you need to have a plan to re-treat or follow up in such a way that it addresses the entire life cycle of lice. It’s important when choosing a lice treatment for your family that you consider the individual needs of everyone in your household, including allergies and skin sensitivities. While tea tree oil is a natural head lice treatment, topical use can cause side effects like burning, rash or stinging, among others. Inhaled, tea tree oil can cause headache, nausea and vertigo. We recommend that you follow the aforementioned steps but leave out the tea tree oil for a safer and effective lice treatment.
