Your hair is one of the most important parts of your body. Hair is made up of cells, with keratin, that grows from follicles found in the dermis. The human body, apart from the palms of the hands and soles of the feet, is covered in follicles which produce thick terminal and fine hair, short, fine, lightly colored and barely noticed hair that develops everywhere on the human body. The part beneath the skin is called a hair follicle or when pulled out of the head it’s called a bulb.
It is nothing but dead shaft above the scalp. A typical hair shaft is made up of three layers, cuticle, medulla and cortex. The cuticle is the outermost layer. It protects the medulla and cortex. The cuticle is a see through structure and only this layer gives the shiny look. If this outer layer is not healthy then you will still get flat hair look. Medulla is the innermost layer and has large size cells. The cortex also is in the middle layer. This takes over a protein called keratin and coloring pigments. The cortex determines the shape and size of the hair shaft.
