What causes scalp problems?

There are many things that can trigger problems with the scalp: Stress, illness, diet and hereditary reasons are all common. 

Scalp Disorders are caused by skin cells forming too fast. The epidermis, or outer, protective layer of the skin, is constantly changing. The cells begin to frow from the base layer deeper in the skin and gradually move to the surface. This is called the epidermul turnover. Normally it takes approximatley 28 days for the cells to move through the skin and to reach the surface. Once there they come away when we wash. 

An increase in epidermal turnover can be caused or exacerbated by abnormally high levels of Malassezia Globosa- a yeast native to us and always found on the scalp (even a healthy scalp). Problems often occur when the quantity of malassezia yeast increases.
