Lavender essential oil recently gained attention for stimulating hair growth. A 2016 studyTrusted Source found that lavender oil applied to mice made them grow more hair. Their hair also grew thicker and faster than normal.
This benefit is way more effective when the oil can work itself into the skin. Per these studies, lavender oil may help with issues like pattern baldness or alopecia. Human studies are needed to prove this, though people can safely try the oil in their hair.
Lavender also has antimicrobial properties, noted in this 2014 review. This means it helps prevent bacteria and fungi from growing.
When applied to hair or scalp, this may prevent common hair or scalp issues. In particular, it may prevent itchy scalp or dandruff and even infections.
A 2011 studyTrusted Source found that lavender essential oil could help prevent head lice. It may even kill head lice.
The study tested lavender with another essential oil, tea tree oil. Though more studies are needed, using lavender oil could possibly reduce the risk of getting lice. Using tea tree oil with it could be even more successful.
But that doesn’t mean these oils are a replacement for your prescribed treatment plan — you shouldn’t rely solely on oils to treat head lice.
Lavender is sometimes used as a home remedy for skin inflammation and burns. Using it in essential oil form may be good for scalp inflammation and dryness.
A 2012 study saw lavender oil used topically on skin inflammations and ulcers, with success. It reduced inflammation and sped up the healing process.
As an extra benefit, lavender has a wonderful smell. Its aroma can literally calm down your nervous system. In this 2012 experiment, human subjects experienced more relaxation, pleasure, and better moods after inhaling its fragrance.
