10 Best Herbal Essential Oils For Lice
Herbal essential oils, such as lavender, tea tree, and neem, are commonly used as natural remedies for lice due to their antimicrobial and insecticidal properties.
These oils can help repel and eliminate lice by disrupting their life cycle and inhibiting their ability to cling to hair shafts. When diluted properly with a carrier oil, they can be safely applied to the scalp and hair to reduce infestation without the harsh side effects of chemical treatments. However, it is important to note that while some studies suggest their effectiveness, they may not completely eradicate lice on their own and may require consistent application.
As a result, many individuals combine essential oils with combing techniques and other natural remedies for optimal results.
