The Human Hair Structure
- The Hair Cuticle: is formed from dead cells which form scales that gives the hair shaft strength and the hair cuticle does the best job of providing protection. The hair cuticle is the first line of defense against all forms of damage because it is responsible for much of the mechanical strength of the hair fiber, as well as controls the water content of the fiber. Much of the shine that makes healthy hair glow flawless is due to the hair cuticle. The hair cuticle is often damaged by excessive mechanical manipulation such as brushing, using heat like curling tools, or chemical processing such as (texturizers, perms, relaxers, or color) and everyday elements like the sun, wind, or rain.
- The Hair Cortex: makes up majority of the hair shaft, determines the hair color and whether your hair will be straight or curly, and the hair cortex is responsible for the strength, thickness, and flexibility of the hair. When you see split ends then you know that your first line of defense the hair cuticle is damaged the fibers of the cortex begins to unravel causing the hair to become dry, brittle, and prone to tangles and split ends. When the hair cortex is damaged then it is time for a protein treatment which is designed to add strength and elasticity to your hair.
- The Hair Medulla: is the inner most layer, responsible for 90% of the total weight of the hair, and is composed of large, loosely connected keratinized cells. In human hair the medulla may be as much as 1/3 of the diameter of the hair fiber and the formation of the medulla cells can be continuous, discontinuous, or fragment. In coarse hair the diameter is usually continuous or fragmental and where as in fine hair it appears to be discontinuous or absent all together. This is the layer of the hair where chemical changes takes place when you change the color of your hair, have a permanent wave, or relaxer chemical service.
