The most common form of baldness seen is male pattern baldness, in which the hair recedes from the lateral sides of the forehead, known as "receding brow". Additionally, a bald patch can develop on top (vertex). The trigger for this type of baldness, which is also known as androgenetic alopecia, is currently believed to be an enzyme, 5-alpha reductase, that converts the hormone testosterone into dihydrotestosterone (DHT), which inhibits hair growth. The age at which the enzyme appears, if it does at all, is genetically determined. Male pattern baldness is being classified on the Hamilton-Norwood scale I-VIII.
Female pattern baldness, in which the midline parting of the hair appears broadened, is less common. It is believed to result from a decrease in estrogen, a hormone that normally counteracts the balding effect of testosterone, which normally occurs in women's blood. Female pattern baldness is being classified on the Ludwig scale I-III.
Traction alopecia is commonly found in women with ponytails or cornrows that pull on their hair with excessive force.
Traumas such as chemotherapy, childbirth, major surgery and severe stress may cause a hair loss condition known as telogen effluvium.
Factors such as a regular lack of sufficient sleep can trigger the onset of hair loss in individuals who are genetically prone to the condition.
Some mycotic infections can cause massive hair loss.
The emotional impact on persons experiencing hair loss varies widely.
Many men take an accepting approach to their hair loss. They see it as nature taking its course. They may not attempt to reverse or hide the hair loss. They may even shave off the rest of their hair. Some of them are proud to be bald, sharing the charisma of famous film actors, such as Yul Brynner, Telly Savalas and Patrick StewartPatrick Stewart (born July 13, 1940) is a famous British film and television actor. His bald head and classically trained vocal mannerisms are his trademarks. He was born in Mirfield, Yorkshire, England. His first appearance on stage was at a local outdoo, who have been considered handsomely distinctive, virile and epitomizing masculinity, in part, because of their baldness.
Others, however, see hair loss as a devastating event, perhaps due to a perceived loss of youth. For women, there can also be a feeling of loss of femininity. They might feel that baldness will make them unattractive to themselves or others.
Those considering treatment for hair loss should carefully consider the alternatives before proceeding, which may include consulting with a physician.
One method of hiding hair loss — a method which received U.S. patentThe United States Patent and Trademark Office PTO or USPTO is an agency in the United States Department of Commerce that provides patent and trademark protection to inventors and businesses for their inventions and corporate and product identification. 4,022,227 [1] — is the comb-over, which involves restyling the remaining hair to cover the balding area. It is usually a temporary solution, possible only while the area of hair loss is small. As the hair loss grows, a comb-over becomes increasingly ineffective.
Another method is to wear a wigFor an article on stock index see WIG, for the Wing In Ground effect see Ground effect. A wig or toupee is a head of hair human, horse-hair or synthetic worn on the head for fashion or various other aesthetic and stylistic reasons, including cultural and, toupeeA toupee is a small hairpiece worn by men to cover partial baldness. See also Wig., or hairpiece. The wig is a layer of artificial or natural hair made to resemble a typical hair style. In most cases the hair is artificial. Wigs vary widely in quality and cost. The best wigs - those that look like real hair - cost up to tens of thousands of dollars. Some organizations collect individuals' donations of their own natural hair to be made into wigs for young cancerFor other meanings of Cancer: see Cancer (disambiguation . apoptosis; cancer cells, however, avoid apoptosis. Cancer is a group of related diseases characterized by uncontrolled cell division. Currently, it is believed that cancers arise from both genetic patients who have lost their hair due to chemotherapy or other cancer treatment.
Some drugs are used to avoid hair loss. RogaineRogaine is the brand name for Minoxidil, when used as a topical drug to treat male pattern baldness. The solution is applied to the scalp daily to stimulate hair growth and help prevent hair loss. It is available over-the-counter (OTC) in the U. in a 2% M and Propecia are prescription medications that are used to stop baldness and reverse hair loss in hereditary cases. Propecia is a pill that can work against baldness, but if the person stops taking it, the baldness usually returns. Rogaine is a solution that is rubbed directly into the head. The drug regrows hair less than a quarter of the time, however it has been shown to be generally effective in slowing hair loss. There are a number of other products that claim to stop baldness and regrow hair, many of which have not been approved by the United States Food and Drug Administration.
Surgery is another method of reversing hair loss and baldness, although it may be considered an extreme measure. There are various surgical methods used. These include hair transplant s, where patches of skin with hair are moved from one part of the head to another. Another is scalp reduction , where parts of the scalp are removed, the skin is stretched over the area that had been removed, and everything is stitched back together. Stem cells have been discovered in hair follicles and some researchers predict research on these follicle stem cells may lead to successes in treating baldness through hair multiplication within three or four years (as of Nov. 2004). This treatment is expected to initially work through taking stem cells from existing follicles, multiplying them in cultures, and implanting the new follicles into the scalp. Later treatments may be able to simply signal follicle stem cells to give off chemical signals to nearby follicle cells which have shrunk during the aging process, which respond to these signals by regenerating and once again making healthy hair.
