Hair Highlighting
Hair highlighting/lowlighting is changing a person's hair color, using lightener or haircolor to lift the level or brightness of hair strands. Hair colorants primarily come in to different forms: oxidative (permanent) and non-oxidative (semi-permanent and temporary).Permanent hair dyes bleach and add a new color to hair through the penetration of smaller dye precursors into the cortex and subsequent oxidation. There are four basic types of highlights: foil highlights, hair painting, frosting, and chunking. Highlights can be any color, as long as it is a lighter level than the surrounding hair. Hair lightened with bleach or permanent color will be permanent until new growth begins to show. Highlighted hair can make the hair appear fuller. Therefore, it is sometimes recommended for people with thin and fine hair. Basic foil highlighting Foil highlighting is the process of using foil to some strands of hair which will be lightened from particular sections of hair which will remai ...

Hair Color
Human hair color is the pigmentation of human hair follicles and shafts due to two types of melanin: eumelanin and pheomelanin. Generally, the more melanin present, the darker the hair. Its tone depends on the ratio of black or brown eumelanin to yellow or red pheomelanin. Melanin levels can vary over time, causing a person's hair color to change, and one person can have hair follicles of more than one color. Some hair colors are associated with some ethnic groups because of the observed higher frequency of particular hair colors within their geographical region, e.g. straight, dark hair amongst East Asians, Southeast Asians, Polynesians, some Central Asians, and Native Americans; a large variety of dark, fair, curly, straight, wavy or bushy amongst Europeans, West Asians, some Central Asians, and North Africans; and curly, dark, and uniquely helical hair amongst Sub Saharan Africans. Bright red hair is found in some European populations, and hair turns gray, white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hair Bleaching
Hair bleaching is the practice of lightening the hair color, mainly for cosmetic purposes using bleaching agents. Bleaching can be done alone, combined with a toner, or as a step for further hair coloring. The most common commercial bleaching agents in use are hydrogen peroxide and persulfate salts, but historically other agents such as sulfuric acid, wood ash, lye and hypochlorite bleach were used. Hair can also become bleached unintentionally, such as through sun exposure. History During the early years of the Roman Empire, blond hair was associated with prostitutes. The preference changed to bleaching the hair blond when Greek culture, which practiced bleaching, reached Rome, and was reinforced when the legions that conquered Gaul returned with blond slaves. Sherrow states that Roman women tried to lighten their hair, but the substances often caused hair loss, so they resorted to wigs made from the captives' hair. The bleaching agent used by the Roman women was comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hair Coloring
Hair coloring, or hair dyeing, is the practice of changing the color of the hair on humans' heads. The main reasons for this are cosmetic: to cover gray or white hair, to alter hair to create a specific look, to change a color to suit preference or to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching. Hair coloring can be done professionally by a hairdresser or independently at home. Hair coloring is very popular, with 50-80% of women in the United States, Europe, and Japan having reported using hair dye. At-home coloring in the United States reached sales of $1.9 billion in 2011 and was expected to rise to $2.2 billion by 2016. History The dyeing of hair is an ancient art that involves treatment of the hair with various chemical compounds. Assyrian herbals dating back to contain some of the oldest recipes for cosmetic preparations known, including hair dye. The ancient Egyptian Ebers Papyrus, , has recipes for dyein ...

Foil (chemistry)
A foil is a very thin sheet of metal, typically made by hammering or rolling. Foils are most easily made with malleable metal, such as aluminium, copper, tin, and gold. Foils usually bend under their own weight and can be torn easily. For example, aluminium foil is usually about , whereas gold (more malleable than aluminium) can be made into foil only a few atoms thick, called gold leaf. Extremely thin foil is called metal leaf. Leaf tears very easily and must be picked up with special brushes. See also * Aluminium foil * Copper foil * Tin foil * Gold leaf * Metal leaf A metal leaf, also called composition leaf or schlagmetal, is a thin foil used for gilding and other forms of decoration. Metal leaves can come in many different shades, due to the composition of the metal within the metal leaf. Examples of this ... References Metalworking {{Metalworking-stub ...

Hydrogen Peroxide
Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscosity, viscous than Properties of water, water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or "high-test peroxide", decomposes explosively when heated and has been used as both a monopropellant and an oxidizer in rocketry. Hydrogen peroxide is a reactive oxygen species and the simplest peroxide, a compound having an oxygen–oxygen single bond. It decomposes slowly into water and elemental oxygen when exposed to light, and rapidly in the presence of organic or reactive compounds. It is typically stored with a Stabilizer (chemistry), stabilizer in a weakly acidic solution in an opaque bottle. Hydrogen peroxide is found in biological systems including the human body.

Pigment
A pigment is a powder used to add or alter color or change visual appearance. Pigments are completely or nearly solubility, insoluble and reactivity (chemistry), chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use. Dyes are often organic compounds whereas pigments are often inorganic compound, inorganic. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic chemistry, inorganic, organic chemistry, organic, and special pigments were marketed worldwide. According to an April 2018 report by ''Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each yea ...

Plastic Wrap
Plastic wrap, cling film, Saran wrap, cling wrap, Glad wrap or food wrap is a thin plastic film typically used for sealing food items in containers to keep them fresh over a longer period of time. Plastic wrap, typically sold on rolls in boxes with a cutting edge, clings to many smooth surfaces and can thus remain tight over the opening of a container without adhesive. Common plastic wrap is roughly 0.0005 inches (12.7 μm) thick. The trend has been to produce thinner plastic wrap, particularly for household use (where very little stretch is needed), so now the majority of brands on shelves around the world are 8, 9 or 10 μm thick. Materials used Plastic wrap was initially created from polyvinyl chloride (PVC), which remains the most common component globally. PVC has an acceptably-low permeability to water vapor and oxygen, helping to preserve the freshness of food. There are concerns about the transfer of plasticizers from PVC into food. Pliofilm was made of various kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comb
A comb is a tool consisting of a shaft that holds a row of teeth for pulling through the hair to clean, untangle, or style it. Combs have been used since prehistoric times, having been discovered in very refined forms from settlements dating back to 5,000 years ago in Persia. Weaving combs made of whalebone dating to the middle and late Iron Age have been found on archaeological digs in Orkney and Somerset. Description Combs are made of a shaft and teeth that are placed at a perpendicular angle to the shaft. Combs can be made out of a number of materials, most commonly plastic, metal, or wood. In antiquity, horn and whalebone was sometimes used. Combs made from ivory and tortoiseshell were once common but concerns for the animals that produce them have reduced their usage. Wooden combs are largely made of boxwood, cherry wood, or other fine-grained wood. Good quality wooden combs are usually handmade and polished. Combs come in various shapes and sizes depending on what the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopard Pattern
A leopard pattern is a spotted color pattern, particularly in the hair coat or skin of animals, but can also describe spotting patterns in plants and a distinctive print appearing on clothing and other fabrics. In animals In animal world, leopard pattern refers to the black and gold spotted coat of the leopard, but is used to describe many color combinations that result in spots scattered randomly across the skin or hair coat of other animals. Examples of animals with coloring patterns termed ''leopard'' include many great cats in the genus ''Panthera'', the leopard frog, the "leopard" spotting pattern in the Appaloosa and Knabstrupper breeds of horses, the leopard seal, insects such as the giant leopard moth, and fish species such as the leopard darter, leopard shark, and the leopard eel. Examples of plants that use the term include the leopard lily, and the leopard flower. Other animals with leopard patterns include the leopard cat, snow leopard, clouded leopard, leopar ...

Street Fashion
Street style is fashion that is considered to have emerged not from studios, but from the population at large. Street fashion is generally associated with youth culture, and is most often seen in major urban centers. Magazines and newspapers commonly feature candid photographs of individuals wearing urban, stylish clothing. Mainstream fashion often Appropriation (art), appropriates street fashion trends as influences. Most major youth subcultures have had an associated street fashion. Street style is different all around the globe. Description The "street" approach to style and fashion is often based on individualism, rather than focusing solely on current fashion trends. Using street style methods, individuals demonstrate their multiple, negotiated identities, in addition to utilizing subcultural and intersecting styles or trends. This, in itself, is a performance, as it creates a space where identities can be explored through the act(ion) of dress. Bill Cunningham (American p ...
