Rosemary Oil
The sprigs of this pine-scented, woodsy, green herb have a crisp, pungent fragrance that’s easily recognized. To aid hair growth, you can mix a few drops of pure rosemary oil into base oils, such as coconut, olive and castor. For a quick spa treatment for your hair, pour a little of the mixture into a small bowl, warm it up in a pan of hot water and massage into the hair and scalp.
