Taking good care of your hair is an important component of cosmetology. It is one of the first things that everyone sees, and good hair can greatly improve someone's general appearance.
Anatomy of Hair[1]
Hair follicles are located within the first two layers of your skin—the epidermis and the dermis. An individual hair follicle consists of a few different parts; it is primarily the root (dermal papilla), the shaft (or strand), and the sebaceous gland that we are concerned with.
There are three phases to hair growth: anagen, catagen, and telogen. Anagen begins at the root, where the hair gets its blood supply and nutrients it needs to grow, taking anywhere between 2 to 7 years in this stage. Catagen follows, transitioning the hair from a phase of growth to a phase of rest for approximately two weeks. In this stage, the hair detaches from the blood supply at the root. In telogen, the hair sheds, detaching the shaft from the follicle within a period of 4 months.
