Cowlick
A cowlick is a section of human hair that stands straight up or lies at an angle at odds with the style in which the rest of an individual's hair is worn. The most common site of a human cowlick is in the crown, but they can appear anywhere on the head. They also sometimes occur in the front and back of the head. The term "cowlick" dates from the late 16th century, when physician Richard Haydock used it in his translation of Gian Paolo Lomazzo: "The lockes or plaine feakes of haire called cow-lickes, are made turning upwards." Management For people who are very concerned about cowlick management, drastic measures may have to be used. Electrology, waxing, and even cosmetic surgery can be used to permanently alter the cowlick. See also *Ahoge *Hair whorl *Hairy ball theorem References External links * {{Human hair Hairdressing ...

Hairy Ball Theorem
The hairy ball theorem of algebraic topology (sometimes called the hedgehog theorem in Europe) states that there is no nonvanishing continuous function, continuous tangent vector field on even-dimensional n‑sphere, ''n''-spheres. For the ordinary sphere, or 2‑sphere, if ''f'' is a continuous function that assigns a Vector (geometric), vector in to every point ''p'' on a sphere such that ''f''(''p'') is always tangent to the sphere at ''p'', then there is at least one pole, a point where the field vanishes (a ''p'' such that ''f''(''p'') = Null vector, 0). The theorem was first proved by Henri Poincaré for the 2-sphere in 1885, and extended to higher even dimensions in 1912 by Luitzen Egbertus Jan Brouwer. The theorem has been expressed colloquially as "you can't comb a hairy ball flat without creating a cowlick" or "you can't comb the hair on a coconut". Counting zeros Every zero of a vector field has a (non-zero) "Vector field#Index of a vector field, index", and it ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Haydock
Richard Haydock (fl. 1605) was an English physician. He had the first recorded use of the term "cowlick" when he used it in his translation of Gian Paolo Lomazzo: "The lockes or plaine feakes of haire called cow-lickes, are made turning upwards." Biography Haydock was born at Grewel in Hampshire. He was educated at Winchester College, and on 12 July 1588 matriculated at New College, Oxford, of which he was elected a fellow in 1590; he graduated B.A. 16 January 1592, proceeded M.A. 31 October 1595, and M.B. 14 June 1601 (Oxford Univ. Reg. vol. ii. pt. ii. p. 165, pt. iii. p. 169, Oxford Hist. Soc.) He travelled for some time on the continent, whence he returned to Oxford to study physic. In 1605 he left the university and settled in Salisbury, where he practised as a physician for many years. Arthur Wilson (Hist. of Great Britain, ed. 1653, p. 111) says that Haydock used to see visions in the night; that he would select a text in his sleep, and discourse on it in sp ...

Hair
Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. Attitudes towards different forms of hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, gender, or religion. Overview Meaning The word "hair" usually refers to two distinct structures: #the part beneath the skin, called the hair follicle, or, when pulled from the skin, the bulb or root. This organ is located in the dermis and maintains stem cells, which not only re-grow the hair afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gian Paolo Lomazzo
Gian Paolo Lomazzo (26 April 1538 – 27 January 1592; his first name is sometimes also given as "Giovan" or "Giovanni") was an Italians, Italian artist and writer on art. Praised as a painter, Lomazzo wrote about artistic practice and art theory after blindness compelled him to pursue a different professional path by 1571. Lomazzo's written works were especially influential to second generation Mannerism in Italian art and architecture. Early life Born to a family of some social status, Lomazzo appears to have received a better education than most painters. Early indications of his artistic abilities led to his studying with the little-known Giovan Battista della Cerva, Giovanni Battista della Cerva, an assistant of Gaudenzio Ferrari (whom Lomazzo appears to have regarded as his real master). Lomazzo’s autobiography, published with his ''Rime'' in 1587, indicates that he received a steady stream of commissions for murals and altarpieces, once he became an independent mast ...

Electrology
Electrology is the practice of electrical hair removal to permanently remove human hair from the body. Electrolysis is the actual process of removing hair using electricity. In electrolysis, a qualified professional called an electrologist slides a hair-thin, solid metal probe into each hair follicle without puncturing the skin (when inserted properly). Electricity is delivered to the follicle through the probe, which causes localized damage to the areas that generate hairs, either through the formation of caustic sodium hydroxide (the galvanic method), overheating ( thermolysis), or both (the blend method). Methods All three methods (galvanic, thermolysis, and blend) have their own merits, and one method is not better than another. The success depends on the skill of the electrologist, the type of hair being removed, the condition of the skin and the pain threshold of the client. All three methods, when properly performed, can be thorough at destroying the hair matrix cells ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waxing
Waxing is the process of hair removal from the root by using a covering of a sticky substance, such as wax, to adhere to body hair, and then removing this covering and pulling out the hair from the follicle. New hair will not grow back in the previously waxed area for four to six weeks, although some people will start to see regrowth in only a week due to some of their hair being on a different human hair growth cycle. Almost any area of the body can be waxed, including eyebrows, face, pubic hair (called bikini waxing or intimate waxing), legs, arms, back, abdomen, chest, knuckles, and feet. There are many types of waxing suitable for removing unwanted hair. Types Strip waxing (soft wax) is accomplished by spreading a wax thinly over the skin. A cloth or paper strip is applied and pressed firmly, adhering the strip to the wax and the wax to the skin. The strip is then quickly ripped against the direction of hair growth, as parallel as possible to the skin to avoid trauma to th ...

Hair Whorl
A hair whorl (also known as a crown, swirl, or trichoglyph) is a patch of hair growing in a circular direction around a visible center point. Hair whorls occur in most hairy animals on the body as well as on the head, and can be either clockwise, counterclockwise or diffuse in direction of growth. In human theories Hair whorls on the head ( parietal whorls) have been studied by some behaviorists. Most people have clockwise scalp hair-whorls. Parietal whorls which are considered to be normal scalp patterns could be a single whorl or double whorls. Cases of triple parietal whorls are less common. Amar J. S. Klar conducted research to see if there was a genetic link between handedness and hair-whorl direction. He found that 8.4% of right-handed people and 45% of left-handed people have counterclockwise hair-whorls. His research suggested that a single gene may control both handedness and hair-whorl direction.Human handedness and scalp hair-whorl direction develop from a common ge ...
