The parts that make up your hair are:
1.Cortex: The middle layer. It is composed of cells which are tightly bound around one another. These bands provide the hair with elasticity and strength and are very receptive to chemicals. As a result, they can easily be influenced (or damaged) by dyes and relaxers.
2.Cuticle: Outer layer of the hair. It is made up of layers of scales which interlock with the cells of the hair's inner root sheath to firmly anchor it in the follicle. This is a thin and colorless layer. Black hairs cuticle layer can be twice the thickness of that of white hair.
3.Follicle: This is the name for hair before it emerges from the skin. Follicles are composed of many elements including carbon, hydrogen and oxygen. Healthy amounts of these elements can improve the hairs' condition and appearance once it emerges.
4.Melanin: is contained in the cortex and is the substance that determines the color of our hair and skin. The more melanin, the darker the hair or skin.
5.Sebaceous/Sudoniferous Glands: Attached to the hair follicle are the sebaceous (oil) and the sudoriferous (sweat) glands. The sebaceous glands open and close continuously to release a waxy sebum oil into the hair follicle and onto the scalp. The sudoriferous glands contain many small structures with porous openings leading to the skin. They produce substances which dry on the skin including salts, acids, water and bacteria. If not completely dissolved and effectively removed from the scalp, they can help cause severe itching and dandruff. Thus, the scalp problems some people experience in the early stages of locs.
