Signs that your hair needs some extra oil
If your hair just doesn’t feel great, has split ends, appears dull, or is frizzy, you may be dealing with moisture loss, and an oil treatment can be extremely beneficial (via Healthline). Dry hair can be caused by a variety of reasons, from environmental to self-induced. Healthline explains that heat damage, bleaching, living in a dry climate, chlorine, harsh hair products, or over-washing your hair can all cause dry locks. Different types of hair have different needs, as well. Curly hair, for instance, tends to be dryer and may need more added oil, while straight hair is known for being oily (via Vitalize).
