Using this hair essential oil is easy. First, make sure your hair is dry. Then, take a small amount of the oil in your palms and rub them together. Gently massage the oil into your hair, starting from the ends and working your way up to the roots. You can use it daily or as needed. When it comes to storage, keep it in a cool, dry place away from direct sunlight. And don't forget to close the bottle tightly after each use. As for safety, if you have any skin allergies, it's a good idea to do a patch test on a small area of your skin first.
