Structure of HairHair is primarily composed of a protein called Keratin. These strong proteins give the hair strand its structure. A singlestrand of hair is composed of three layers that make up its structure. Hair growth At the base of the hair root, new Cells are formed and these Cells multiply to form a rod of tissue. This rod of Cells moves upward through the skin as new Cells are formed beneath. As these Cellsmove up, the supply of nourishment is cut off and hence, it forms a hard protein called Keratin. This process is known as keratinization and during this process the Cells die. Your hair grows in repeated cycles and is divided into three phases: Anagen: It is the ‘growth phase’, which varies from 2 to 6 years. Your hair grows approximately 10 cm/year. Catagen: It is the ‘transitional phase’, which lasts for 1–2 weeks. During this phase yourHair follicle shrinks and the lower part of the hair and dermal papilla is destroyed. Telogen: This is the ‘resting phase’, which lasts for about 5–6 weeks, during which your hair does not grow. At the end of this phase your Hair follicle reenters into the anagen phase.
