Hair Loss Prevention

Hair is the fastest growing tissue of the body, made up of proteins called keratins. Every strand of hair is made up of three layers: the inner layer or medulla (only present in thick hairs); the middle layer or cortex, which determines the strength, texture, and color of hair; and the cuticle, which protects the cortex. Hair grows from roots, which are enclosed in follicles. Below this is a layer of skin called the dermal papilla, which is fed by the bloodstream carrying nourishment vital to the growth of hair. Only the roots of hair are actually alive, while the visible part of hair is dead tissue, and therefore unable to heal itself. It is vital then to take care of the scalp and body in order to perpetuate hair growth and maintenance.
