Abdominal hair and its characteristics

Abdominal hair The abdominal hair refers to the hair that grows on the abdomen of humans in the region between the pubic area and the chest. The growth of abdominal hair follows the pattern of vertically from the pubic area upwards and from the thorax downwards to the navel. In men Before puberty, the abdominal region of both males and females is covered with very fine vellus hair. In response to rising levels of androgens during and after puberty, the skin of the abdomen begins to produce coarser, longer and more pigmented hair . This process affects primarily men. Initially hair grows in a vertical line from the pubic area up to the navel and from the chest down to the navel. Abdominal hair often indicates young teen men stepping into adulthood. In women Some women may develop a small line of hair from the pubic area up to the navel. many women consider it as unattractive. Excessive abdominal hair on women is called hirsutism. Patterns There are four general patterns of pubic and abd

Underarm hair

Underarm hair and its removal Underarm Hair or armpit hair is the hair which grows in the underarm area. This hair, as most of the other body hair, normally starts to appear at puberty and growth is usually complete by the end of teen age. The release of pheromones from the axilla at this stage of human development suggests association of armpit hair with sexuality. It has been suggested that the hair itself acts with a natural "anti-friction" quality between the upper arm and the thorax. Today, it is more common for women than men to shave off their underarm hair regularly for aesthetic reasons, a practice that may be connected to the overall body hair distribution of sexes. Armpit hair also contributes to intensify the effects of tickling. History of underarm hair removal In the West, the practice of removal of underarm hair began around 1915 in the US and UK, when one or more magazines showed a woman in a dress with shaved underarms. Regular shaving became feasible with th

chest hair

chest hair and its characteristics generally chest hair is the hair that grows on the chest of human males, in the region between the neck and the abdomen. Chest hair, which is considered as a secondary sex characteristic, develops during and after puberty. It is therefore part of the androgenic hair . chest hair Development and growth Although vellus hair is present in the area from childhood, the term chest hair is generally restricted to the terminal hair that develops as an effect of rising levels of androgens due to puberty. In contrast to women the body of men tends to be covered far more with terminal hair, particularly on the chest, the abdomen and the face. The development of chest hair begins normally during late puberty or can start between the age of 20 and 30 . The growth continues subsequently. In older adult years androgens cause thickening of the hair. chest hair Patterns and characteristics The individual occurrence and characteristics of chest hair depend on the horm

Facial hair

Facial hair and its characteristics Facial hair is a secondary sex characteristic in human males. Normally almost all men develop facial hair in the later years of puberty, i.e when they are between 15-18 years old although some men don't finish developing a fully adult beard until their early 20s or later. many women also have some facial hair, especially after menopause, though typically much less than men. Facial hair in men Male pogonotrophy i.e, beardedness, is often culturally associated with wisdom and virility. Many men style their facial hair into moustaches,beards, goatees or sideburns. some men completely shave their facial hair. a man's facial hair, especially short hairs that were missed in shaving, is often referred to as whiskers. Facial hair in women Women typically have little hair on their faces, apart from eyebrows and the vellus hair that covers most of their bodies. However, in some cases women have noticeable facial hair growth. Excessive hairiness,especi

Pubic hair and its characteristics

Pubic hair Pubic hair is hair which grows in the pubic region i.e in the frontal genital area, the crotch, and sometimes at the top of the inside of the legs. Although fine vellus hair is present in the pubic region in childhood, the term pubic hair is generally restricted to the heavier, longer hair that develops with puberty as an effect of rising levels of androgens. Pubic hair is therefore part of the androgenic hair . pubic hair development Before puberty, the genital area of both girls and boys has very fine vellus hair, referred to as Tanner hair. As puberty begins, the body produces rising levels of the sex hormones known as androgens, and in response the skin of the genital area begins to produce thicker, often curlier, hair with a faster growth rate. The onset of pubic hair development is termed pubarche. The change for each hair follicle is relatively abrupt, but the extent of skin which grows androgenic hair gradually increases over several years. There is very little diff
