Hair

Fact:

Hair is a protein filament that grows through the epidermis from follicles deep within the dermis. The main component of hair fiber is keratin. The hair can be divided into three parts length-wise, (1) the bulb, a swelling at the base which originates from the dermis, (2) the root, which is the hair lying beneath the skin surface, and (3) the shaft, which is the hair above the skin surface. In cross-section, there are also three parts, (1) the medulla, an area in the core which contains loose cells and airspaces (2) the cortex, which contains densely packed keratin and (3) the cuticle, which is a single layer of cells arranged like roof shingles.

Human beings have three distinct types of hair:

1-Lanugo is fine hair that covers nearly the entire body of a fetus.

2-Vellus hair is extremely short, fine, scarcely noticeable hair that covers most of the human body in both sexes.

3-Terminal hair is fully developed hair, which is generally longer, coarser, thicker, and darker than vellus hair.

Human scalp hair normally grows at a rate of 0.4 mm/day.

Texture

Hair texture is described as fine, medium, coarse or wiry, depending on the hair diameter. Within the four texture ranges hair can also be thin, medium or thick density and it can range from relatively straight, to wavy, to relatively tightly curled ("kinky"). Hair is genetically programmed to be straight, wavy, curly, or "kinky"

Curly and/or "kinky" hair has a different biological structure from straight hair. It tends to be much drier than straight hair because the oils secreted into the hair shaft by the sebaceous glands can more easily travel down the shaft of straight hair. People with very curly hair may find that this hair type can be dry and often frizzy.

Opinion:

There should be some way to change the genetic makeup of hair... I absolutely HATE my hair! Seriously, what is my hair type even called? It's like wavy on top & some ringlets underneath, with some weird straight places all over... I would be perfectly happy if it was either really wavy all over, really curly all over, or straight all over. But, come on, all 3? Who's idea of a sick joke is that!?

Fact:

Facial hair is a secondary sex characteristic in human males. Male pogonotrophy (the growing of facial hair; i.e, beardedness) is often culturally associated with wisdom and virility.

Leg hair is hair that grows on the legs of humans, generally appearing at the onset of adulthood. Male legs are most often hairier than female ones. For a variety of reasons, people may shave their leg hair. Women generally shave their leg hair more regularly than men because the social norm of many cultures expects them to show a sign of beauty.

Opinion

How is that in any way fair? Men not shaving is associated with wisdom & virtility!? What!? But yet, women are expected to shave or else they're not showing a sign of beauty!? Seriously, that's messed up! Oh, one of the many things that are easier for men!
