What Is Grey Hair? Grey hair is simply a hair follicle that lacks pigment (melanin). A "grey" hair is not actually grey it's "white", when white hair is interspersed with naturally coloured hair it appears grey in colour.
What causes Grey hair? When you will go grey is largely down to your gene pool. If your parents went grey at an early age then you are likely to follow a similar pattern. However, certain health conditions can contribute to you turning grey sooner.
Does Stress Make You Go Grey? Not directly but some conditions cause you to shed hair 3 times faster than normal so when your hair grows back it is possible that your hair grows back a different colour than before.
