What Are the Common Types of Hair?

Human hair is a natural phenomenon that occurs on the body of mammals. Hair grows on all the body parts, except the palms and soles of the feet and flexor surfaces of the joints. It is also a fine, hair-like process found in sensory and auditory cells of the labyrinth. There are many different types of hair. Let’s take a look at some of the most common hair types. What do they have in common?

Hair grows from a root underneath the skin’s surface, pushing outwards through the dermis. A follicle contains a sebaceous gland that produces sebum, a lipid-rich substance that moisturizes and protects the hair. In the base of the hair follicle lies the hair bulb, which contains the cells that make the hair. Blood vessels deliver nutrients to the cells of the hair bulb. The hair follicle grows in length and color as hair cells divide in this specialized area.

In addition to its aesthetic and functional role, hair has many other purposes. On the head, hair serves as a source of insulation and protection from UV radiation, and helps regulate body temperature. However, the function of hair in other parts of the body is still debated, but it’s clear that hair on the head plays an important role in keeping the body warm. It protects the eyes by trapping sweat and acting as a cushion against a cold surface.

As we age, our hair changes in texture, thickness, and location. The shape of the hair shaft also plays a role in the amount of shine in the strands. Straight hair tends to be shinier than curly hair, since the sebaceous gland can easily transport sebum down the strands. Curly hair has a difficult time traveling down the strands. As a result, it lacks shine.

Early modern China saw the development of the queue. Manchus of central Manchuria wore this hairstyle, as did Han Chinese during the Qing dynasty. Men shaved their hair in the front of their heads every ten days to mimic male pattern baldness. Hair was then braided into a long pigtail. It was considered an important symbol of sexual maturity in the society. These are just some of the hairstyles that people wore during the 19th century.

Hair is a complex system of layers. A small muscle known as the arrector pili attaches the hair follicle to the skin and provides nourishment to the strands of hair. It also contains many nerves that sense movement and are very sensitive to even the slightest draft. The root of a hair bulb is a round structure that widens into a rounded hair bulb. The hair bulb is the place where new hair cells are created.

Humans have four main types of hair. The first is called lanugo and begins to grow in the third or fourth month of embryonic development. It sheds shortly after birth. The second type, known as vellus, is much heavier and deeper pigmented. It covers almost every part of the body, except the palms and soles of the feet. Once the body reaches puberty, these hairs form armpit and pubic hair.
