Hair is the fastest growing tissue of the body. It is made of keratins which are a type of proteins. Each hair strand includes three layers: the medulla (the inner layer), the cortex and the cuticle. Hair grows from roots – Those roots get the vital ingredients to the hair growth by the blood. The roots are a living tissue but the visible hair strand is a dead tissue.
