Due to its impressive anti-fungal and anti-inflammatory properties, citronella essential oil can help treat scalp conditions such as dandruff or general dryness. It works to moisturize the scalp, which can strengthen and hydrate hair, prevent frizziness, and stop skin flaking.
If you want to use citronella oil to treat dandruff, you should mix a few drops of the oil into your shampoo or a carrier oil and apply it daily. Make sure to rinse out the shampoo or oil after each use. For dry hair, add a few drops of citronella oil into your conditioner each time you use it.
To create a hydrating hair mask, mix several drops of citronella oil with your favorite premade hair mask or a hydrating carrier oil (such as coconut) and apply it liberally to damp hair. Let the mask sit on your hair for 5 to 15 minutes and then rinse off. Repeat this process one to two times a week for best results.
