Why does my hair get greasy?

Want to know the reason why your hair gets oily? Peter breaks down the biology: “within the hair follicle, there is something called the sebaceous gland which is responsible for producing sebum.”

“Made up of a cocktail of lipids or fatty materials, sebum makes its way up out of the follicle along the hair fibre.” This is what forms an oily or coating over the hair surface, and can make it feel greasy or dirty.

“In addition, if the sebum is allowed to remain on the hair for a long period of time it can be attacked and broken down by the micro-organisms on the scalp.  The by-products of this process can also have a strong odour.” Yikes.
