Greasy or Oily Hair
Greasy hair can be caused by hormones in younger people, or by exercise and sweating in just about anyone else. It can look lank, oily and lifeless if left to its own devices. On the plus side, greasy hair is in fact healthy hair, since all that oil protects each strand from dryness and split ends. Greasy hair needs to be kept clean by frequent washing with a mild shampoo and conditioners should be oil free and used sparingly.
