We live in a hairy world; and we are hairy people. In fact, hair covers virtually every part of our bodies with the exception of the palms of our hands and the soles of our feet. Hair is composed of a protein call keratin, and this keratin produces a follicle (fiber) that grows from the outermost layer of skin at a rate of roughly 6 inches per year. Although hair grows on most of the body, we are chiefly concerned with that which makes its home on our heads. Full, beautiful luxurious hair is coveted, so keeping it in tact is a top priority.
