Hair

glabrousglabrescenthuman hair
It is differentiated from the head hair and less visible vellus hair, which is much finer and lighter in color.
The body has different types of hair, including vellus hair and androgenic hair, each with its own type of cellular construction.

Pubic hair

Pubic hair is a collection of coarse hair found in the pubic region.
Pubic hair is terminal body hair that is found in the genital area of adolescent and adult humans.

Puberty

pubescentpubescencesexual development
Body hair, or androgenic hair, is the terminal hair that develops on the human body during and after puberty.
In the months and years following the appearance of pubic hair, other areas of skin that respond to androgens may develop androgenic hair.

Vellus hair

vellusVelli
It is differentiated from the head hair and less visible vellus hair, which is much finer and lighter in color.
Vellus hair is differentiated from the more visible terminal or androgenic hair, which develops only during and after puberty, usually to a greater extent on men than it does on women.

Hypertrichosis

Ambras syndromeWerewolf syndromeAcquired generalized hypertrichosis
In some cases, female beard growth is the result of a hormonal imbalance (usually androgen excess), or a rare genetic disorder known as hypertrichosis.
The excess growth of hair occurs in areas of the skin with the exception of androgen-dependent hair of the pubic area, face, and axillary regions.

Anabolic steroid

anabolic steroidsanabolic-androgenic steroidanabolic–androgenic steroid
Sometimes it is caused by use of anabolic steroids.
They are anabolic and increase protein within cells, especially in skeletal muscles, and also have varying degrees of androgenic and virilizing effects, including induction of the development and maintenance of masculine secondary sexual characteristics such as the growth of facial and body hair.

Androgen

androgensandrogenicAndrogenic steroid
In some cases, female beard growth is the result of a hormonal imbalance (usually androgen excess), or a rare genetic disorder known as hypertrichosis. The growth of androgenic hair is related to the level of androgens (often referred to as male hormones) and the density of androgen receptors in the dermal papillae.
Masculine secondary sexual characteristics include androgenic hair, voice deepening, emergence of the Adam's apple, broadening of the shoulders, increased muscle mass, and penile growth.

Testosterone

Hair follicles are to varying degrees sensitive to androgen, primarily testosterone and its derivatives, particularly dihydrotestosterone, with different areas on the body having different sensitivity.
In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.

Shaving

Today in much of the world, it is common for women to regularly shave their underarm hair.
In some Native American tribes, at the time of contact with British colonists, it was customary for men and women to remove all body hair using these methods.

Dihydrotestosterone

5α-DihydrotestosteroneDHT17-hydroxyandrostan-3-one
Hair follicles are to varying degrees sensitive to androgen, primarily testosterone and its derivatives, particularly dihydrotestosterone, with different areas on the body having different sensitivity.
DHT is biologically important for sexual differentiation of the male genitalia during embryogenesis, maturation of the penis and scrotum at puberty, growth of facial, body, and pubic hair, and development and maintenance of the prostate gland and seminal vesicles.

Human hair growth

catagenhair growthgrowth
Androgenic hair follows the same growth pattern as the hair that grows on the scalp, but with a shorter anagen phase and longer telogen phase.
The body has different types of hair, including vellus hair and androgenic hair, each with its own type of cellular construction.

Chest hair

This includes facial hair, chest hair, abdominal hair, leg hair, arm hair, and foot hair.
Chest hair develops during and after puberty along with other types of androgenic hair.

Terminal hair

Body hair, or androgenic hair, is the terminal hair that develops on the human body during and after puberty.
This includes facial hair, chest hair, abdominal hair, leg and arm hair, and foot hair.

Leg hair

Hair removal

Hair removal, also known as epilation or depilation, is the deliberate removal of body hair.

Hirsutism

Hirsutism is excessive body hair in men and women on parts of the body where hair is normally absent or minimal.

They summarize other studies on prevalence of this trait as reporting, in general, that Caucasoids are more likely to have hair on the middle finger joint than Negroids and Mongoloids, and collect the following frequencies from previously published literature: Andamanese 0%, Eskimo 1%, African American 16% or 28%, Ethiopians 25.6%, Mexicans of the Yucatan 20.9%, Penobscot and Shinnecock 22.7%, Gurkha 33.6%, Japanese 44.6%, various Hindus 40–50%, Egyptians 52.3%, Near Eastern peoples 62–71%, various Europeans 60–80%.

The Jōmon shared some physical characteristics, such as relatively abundant body hair and light skin, with Caucasians, but anthropological genetics shows them to derive from a separate genetic lineage from that of Europeans.

Human body

Body hair, or androgenic hair, is the terminal hair that develops on the human body during and after puberty. From childhood onward, regardless of sex, vellus hair covers almost the entire area of the human body.

Androgenic hair follows the same growth pattern as the hair that grows on the scalp, but with a shorter anagen phase and longer telogen phase. The density of hair – i.e. the number of hair follicles per unit area of skin – varies from person to person.

Beard

In many cases, areas on the human body that contain vellus hair will begin to produce darker and thicker body hair, such as the first growth of beard hair on a male and female adolescent's previously smooth chin; although it may appear thinner on the female.
