What is Hair ?

Concept of Hair is complex than it appears on the surface. We know that it not only plays a vital role in the appearance of both men and women, but it also helps to transmit many information as well as create gender identification in both Men and Women.

Origin Of Hairs ?

In Human Body Developing fetus has its hair follicles made. At this stage (20 weeks) of life there are about 4.5 million hair follicles on the human body. There are a total of half million on the head, with one hundred thousand of those follicles residing on the scalp. This is the largest number of hair follicles a human will ever have in lifetime, since we do not generate new hair follicles anytime during the course of our lives.

What are Hair Follicles ?

Hair has two distinct structures one is the follicle which grows in the skin, and second is the shaft, which is what is visible above the scalp in human body.

The hair follicle is a tunnel-like segment of the epidermis that extends down into the dermis. This structure contains many layers that all have separate functions. At the base of the follicle is the papilla, which contains capillaries, or tiny blood vessels that nourish the cells in human body. The living part of the hair is the bottom part surrounding the papilla, called the bulb. The cells of the bulb divide every 24 to 70 hours, remarkably faster than any other cell in the human body.

What is Hair Shafts ?

In Human Body The hair shaft is made of a hard protein called keratin and is made in three layers in time to time. This protein is actually dead, so the hair that you see is not a living structure. The inner layer is the medulla. The second layer is the cortex and the outer layer is the cuticle in Body (Scalp). The cortex makes up the majority of the hair shaft. The cuticle is a tightly formed structure made of shingle-like overlapping scales. It is both the cortex and the medulla that holds the hair’s pigment, giving it its color.
