            Hair is an important factor of Americans in today’s society. Long, short, straight, and course hair it varies depending on the person who wearing it. Many people wonder why black people have course hair. Others wonder why whites have naturally long oily hair. In my paper I plan to discuss the dynamics of different textures of hair. “Everyone has the same hair structure no matter whose head it’s on.” “All human hair consists of three main layers which include the cuticle, the cortex and the medulla.”(http://nappyme.wordpress.com/hair-facts/)  

The outer layer of your hair is called the cuticle. The cuticle is designed to protect the inner layers of your hair shaft. Many people compare your cuticles to shingles on a roof. Studies show that cuticles that lay flat against the hair shaft do the best job of providing protection. Many people damage their cuticles and don’t even know it. Cuticles are often damaged by a variety of things such as brushing your hair. Your cuticles can also be damaged by using heat or chemical processing. Cuticles can be damaged by every day elements. Things such as the sun or wind can cause wear and tear on your hair and damage your cuticles as well. The second layer of hair is called the cortex. The cortex is made up of long proteins that are twisted. Some people say they remind them of a curly telephone cord. The cortex plays an important part of your hair overall feature. The cortex is what determines your hair’s overall strength, elasticity, and color. A damaged cortex can result in split ends. The protective cuticle has been worn away and is now exposing your cortex. Once your cortex is exposed, the hair is damaged beyond repair. Hair isn’tAliving tissue, it doesn’t have the healing properties that your skin does to regenerate itself. Studies show that dealing with damaged hair its best to use varies of products but once your hair is damaged it can never be fixed. Damaged hair will either break on its own. Its best in the case of split ends to eventually get your hair trimmed. The innermost or center portion of the hair shaft is called the medulla.  The medulla is composed of round cells, two to five rows across. Thick or coarse hair usually contains a medulla. Fine hair for the most part lacks a medulla, Blonde hair also lacks medulla. (http://nappyme.wordpress.com/hair-facts/) Blacks have naturally course hair.Afro-textured hair is a term used to refer to the typical texture of Black Africanhair that has not been touched by hot combs, flat irons, or chemicals. Each strand of this hair type grows in a tiny spring-like, corkscrew shape. This texture appears, and feels denser than its straight counterparts. Many people will call afro-textured hair thick, bushy, coarse or wooly hair.  “In time afro-textured hairstyles were used to define status, or identity, in regards to age, ethnicity, wealth, social rank, marital status, religion, fertility, manhood, and even death”. Afro-textured hair may have initially evolved due to an adaptive need amongst humanity's hominid ancestors for protection against the intense UVradiation of Africa . Due to the fact that afro hair was very course and spring like, this resulted in an increased circulation of cool air onto the scalp. This may have served to facilitate Africans ancestors’ body temperature to be regulated while they lived in the open savannah. Afro-hair does not respond as easily to moisture and sweat as straight hair does. Instead of sticking to the neck like straight hair does and scalp when wet unless totally drenched, it tends to retain its basic springy puffiness. In addition to the above-listed causes, the trait may have also been retained among many equatorial human groups due to its contribution to enhanced comfort levels under warm conditions. Hair was carefully groomed by those who understood the artistic standard as the social suggestions of hair grooming was a significant part of tribal life. “Dense, thick, clean and neatly...
