Yes, hair oils can help treat your scalp folliculitis. But you must make sure that you only use natural, cold-pressed hair oils with no synthetic perfumes or coloring. Develop a hair and scalp care routine of oiling your hair and massaging your scalp with a nourishing oil every alternate night. Wash off the oil the next morning. You should see a considerable difference in the quality of your hair as well as a significant reduction in scalp problems.
