Natural Hair Growth

Natural Hair Growth

Humans have studied the science of natural hair growth for centuries. Hair has long been a symbol of status, vitality and beauty in many ancient cultures so our fascination with it is understandable. The structure of a strand of hair in itself is very fascinating. Hair is composed of fibrous structural proteins, called Keratin. Each strand of the hair has three morphological layers:


  1. Cuticle: A translucent outer layer of the hair shaft
  2. Cortex: The main body of the hair
  3. Medulla: The innermost layer of the hair
Hair Morphology


It is a thin colorless layer that protects your innermost layers of the hair shaft. It is formed from dead cells and is the first line of defense against all forms of hair destruction. Coronal, Spinous, and Imbricate are three basic structures that make up the cuticle. The appearance of your hair depends on the overall health of your cuticle. The cuticle layer of the hair plays a vital role in your hairs growth.


The Cortex is located between the cuticle and medulla layer, which provides the strength and determines the color, pattern, thickness and overall texture of your hair. It is the main part of the hair that is composed of elongated and fusiform cells. The shape of the cortex determines whether you’ve got curly or straight hair. If the cross section of the cortex is round shaped, the pattern of your hair will be straight. On the other hand, if the cortex is oval shaped, the pattern of your hair will be either wavy or curly.


The medulla is comprised of loosely connected fibrous structural protein cells with air space in between. The layers of Keratin cells and air space determine the thickness of your hair. The cortex contains metabolized amino acids (melanin) that gives color to your hair.

Hair Growth- How Hair Grow
How the Hair grows

  1. Your hair starts rising from a root in the bottom of the follicle (a tube-like place in the hair). Your hair roots are made up of cells of protein. Blood from the blood vessels in your scalp feeds and aids your hair roots, which give rise to more cells and increase the hair growth.


  1. As your hair grows, the hair gets pushed up through the skin, passing an oil gland along the way. The sebaceous gland adds oil to your hair in order to keep them soft and shiny. This oil can make your hair oily, too. That’s why you need to wash your hair once or twice a week.


  1. Your hair perishes by the time it is long enough to come out through the skin. Yes, the hair outside the scalp is only a combination of keratin and dead skin cells, that’s why it doesn’t hurt to get a haircut.
