Hair-straightening
Hair straightening is a hair styling technique used since the 1890s involving the flattening and straightening of hair in order to give it a smooth, streamlined, and sleek appearance. It became very popular during the 1950s among black males and females of all races. It is accomplished using a hair iron or hot comb, chemical relaxers, Japanese hair straightening, Brazilian hair straightening, or roller set/blowdryer styling. In addition, some shampoos, conditioners, and hair gels can help to make hair temporarily straight. The process is often called "rebonding" in some countries from Southeast Asia (e.g. Indonesia, Singapore, Malaysia and Philippines). If done often, flat irons and chemicals can be damaging to hair. Excessive straightening often results in split ends. However, heat protectant sprays can decrease the damage. Methods Temporary (non-chemical treatment) Hair irons and hot combs are designed to temporarily modify the shape/texture of hair. The straightened effe ...

Heat
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straightening Comb
A hot comb (also known as a straightening comb or pressing comb) is a metal comb that is used to straighten moderate or coarse hair and create a smoother hair texture. A hot comb is heated and used to straighten the hair from the roots. It can be placed directly on the source of heat or it may be electrically heated. History The hot comb was an invention developed in France as a way for women with coarse curly hair to achieve a fine straight look traditionally modeled by historical Egyptian women. Parisian Francois Marcel Grateau is said to have revolutionized hair styling when he invented and introduced heated irons to curl and wave his customers' hair in France in 1872. His Marcel Wave remained fashionable for many decades. Britain's Science and Society Library credits L. Pelleray of Paris with manufacturing the heated irons in the 1870s. An example of an 1890s version of Pelleray's curling iron is housed at the Chudnow Museum in Milwaukee. Elroy J. Duncan is believed to ha ...

African American
African Americans (also referred to as Black Americans and Afro-Americans) are an ethnic group consisting of Americans with partial or total ancestry from sub-Saharan Africa. The term "African American" generally denotes descendants of enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West/ Central African with some European descent; some also have Native American and other ancestry. According to U.S. Census Bureau data, African immigrants generally do not s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madame CJ Walker
Madam C.J. Walker (born Sarah Breedlove; December 23, 1867 – May 25, 1919) was an African American entrepreneur, philanthropist, and political and social activist. She is recorded as the first female self-made millionaire in America in the ''Guinness Book of World Records''. Multiple sources mention that although other women (like Mary Ellen Pleasant) might have been the first, their wealth is not as well-documented. Walker made her fortune by developing and marketing a line of cosmetics and hair care products for black women through the business she founded, Madam C. J. Walker Manufacturing Company. She became known also for her philanthropy and activism. She made financial donations to numerous organizations such as the NAACP, and became a patron of the arts. Villa Lewaro, Walker's lavish estate in Irvington, New York, served as a social gathering place for the African-American community. At the time of her death, she was considered the wealthiest African-American businesswom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hair Follicle
The hair follicle is an organ found in mammalian skin. It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions. The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells. This complex interaction induces the hair follicle to produce different types of hair as seen on different parts of the body. For example, terminal hairs grow on the scalp and lanugo hairs are seen covering the bodies of fetuses in the uterus and in some newborn babies. The process of hair growth occurs in distinct sequential stages. The first stage is called ''anagen'' and is the active growth phase, ''telogen'' is the resting stage, ''catagen'' is the regression of the hair follicle phase, ''exogen'' is the active shedding of hair phase and lastly ''kenogen'' is the phase between the empty hair follicle and the growth of new hair. The function of hair in humans has long been a subject of interest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interferon Alpha
The type-I interferons (IFN) are cytokines which play essential roles in inflammation, immunoregulation, tumor cells recognition, and T cell, T-cell responses. In the human genome, a cluster of thirteen functional IFN genes is located at the 9p21.3 cytoband over approximately 400 kb including coding genes for IFNα (''IFNA1, IFNA2, IFNA4, IFNA5, IFNA6, IFNA7, IFNA8, IFNA10, IFNA13, IFNA14, IFNA16, IFNA17'' and ''IFNA21''), IFNω (''IFNW1''), IFNɛ (''IFNE''), IFNк (''IFNK'') and IFNβ (''IFNB1''), plus 11 IFN pseudogenes. Interferons bind to interferon receptors. All type I IFNs bind to a specific cell surface receptor complex known as the IFN-α receptor (Interferon-alpha/beta receptor, IFNAR) that consists of IFNAR1 and IFNAR2 chains. Type I IFNs are found in all mammals, and homologous (similar) molecules have been found in birds, reptiles, amphibians and fish species. Sources and functions IFN-α and IFN-β are secreted by many cell types including lymphocytes (NK cells, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hair Dryer
A hair dryer, hairdryer or blow dryer is an electromechanical device that blows ambient or hot air over damp hair to speed the evaporation of water to dry the hair. Blow dryers enable better control over the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds within each strand. These bonds are powerful (allowing stronger hair shaping than the sulfur bonds formed by permanent waving products) but are temporary and extremely vulnerable to humidity. They disappear with a single washing of the hair. Hairstyles using blow dryers usually have volume and discipline, which can be further improved with styling products, hairbrushes, and combs during drying to add tension, hold and lift. Blow dryers were invented in the late 19th century. The first, stationary, model was created by Alexander F. Godefroy in his salon in France. The handheld, household hair dryer first appeared in 1920. Blow dryers are used in beauty salons by professional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
