Hair that develops a lank, flat, stringy or oily appearance is often referred to by hairdressers and hair consumers as “greasy” hair. This type of hair is hard to control, clumps together easily and does not hold a style well.
Where does greasy hair originate from? Regardless of how or why it happens, greasy hair is directly related to the overproduction of sebum, a waxy type of substance naturally occurring in the body which is designed to keep hair supple, soft and waterproof. Sebum is produced by the sebaceous glands.
