The outer layer is called the cuticle and is thin and colorless, its job is to protect the thicker cortex which contains the melanin. Melanin is the reason for different hair colors and the actual colour of your hair depends on what type of melanin you have. There are two kinds, eumelanin which creates brown or black hair, and pheomelanin which makes hair appear red. Blonde hair is a result of very low amounts of melanin, the shade of the blonde again depends upon which type of melanin you have. A lack of melanin can result in tray hair. Grey hair can also be caused by age but can also be caused by stress and illness.  Sadie C. http://www.hairlosshelp.com/hair_loss_research/hair.cfm
