Weaves
Artificial hair integrations, more commonly known as hair extensions, hair weaves, and fake hair add length and fullness to human hair. Hair extensions are usually clipped, glued, or sewn on natural hair by incorporating additional human or synthetic hair. These methods include tape-in extensions, clip-in or clip-on extensions, micro/nano rings, fusion method, weaving method, and wigs. Background A hair weave is a human or artificial hair utilized for integration with one's natural hair. Weaves can alter one's appearance for long or short periods of time by adding further hair to one's natural hair or by covering the natural hair together with human or synthetic hairpieces. Weaving additional human or synthetic pieces can enhance one's hair by giving it volume and length, and by adding color without the damage of chemicals or by adopting a different hair texture than that of their own. However, hair loss can occur either along the front hairline or above the ears due to the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weaving
Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, crocheting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling. (''Weft'' is an Old English word meaning "that which is woven"; compare ''leave'' and ''left''.) The method in which these threads are interwoven affects the characteristics of the cloth. Cloth is usually woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. A fabric band that meets this definition of cloth (warp threads with a weft thread winding between) can also be made using other methods, including tablet weaving, back strap loom, or other techniques that can be done without looms. The way the warp and filling threads interlace with each other is called the weave. The majority of woven pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toupée
A toupée ( ) is a hairpiece or partial wig of natural or synthetic hair worn to cover partial baldness or for theatrical purposes. While toupées and hairpieces are typically associated with male wearers, some women also use hairpieces to lengthen existing hair, or cover a partially exposed scalp. The toupée developed during the 18th century. Toupées and wigs While most toupées are small and designed to cover bald spots at the top and back of the head, large toupées are not unknown. Toupées are often referred to as hairpieces, units, or hair systems. Many women now wear hairpieces rather than full wigs if their hair loss is confined to the top and crown of their heads. Etymology ''Toupée'' comes from the French ''toupet'', meaning tuft of hair, as in a curl or lock of hair at the top of the head, not necessarily relating to covering baldness. History 18th century The toupée developed during the 18th century, large toupées were popular in the 1770s. Their popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human 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, sex, or religion. Overview 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 after it falls ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Young Woman (Adriana) At Tourist Office - Cachoeira - Bahia - Brazil
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Thro ...

Venkateswara
Venkateswara, also known by various other names, is a form of the Hindu god Vishnu. Venkateswara is the presiding deity of the Tirumala Venkateswara Temple, located in Tirupati, Sri Balaji District, Andhra Pradesh, India. Etymology Venkateswara literally means, "Lord of Venkata". The word is a combination of the words ''Venkata'' (the name of a hill in Andhra Pradesh) and ''isvara'' ("Lord"). According to the ''Brahmanda'' and '' Bhavishyottara'' Puranas, the word "Venkata" means "destroyer of sins", deriving from the Sanskrit words ''vem'' (sins) and ''kata'' (power of immunity). It is also said that 'Venkata' is a combination of two words: '''ven''' (keeps away) and kata''' (troubles). Venkata means he 'who keeps away troubles' or 'who takes away problems' or such terms in a similar context. Legend Every year, hundreds of thousands of devotees donate a large amount of wealth at the Tirumala Venkateswara Temple at Tirupati, Andhra Pradesh. A legend provides the reason fo ...

Cuticle (hair)
The hair cuticle is the outermost part of the hair shaft.James, William; Berger, Timothy; Elston, Dirk (2005) ''Andrews' Diseases of the Skin: Clinical Dermatology'' (10th ed.). Saunders. Page 8. . It is formed from dead cells, overlapping in layers, which form scales that strengthen and protect the hair shaft. While the cuticle is the outermost layer, it is not responsible for the color of the hair. Melanin is the pigment that gives hair its color Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes.

Cortex (hair)
The cortex of the hair shaft is located between the hair cuticle and medulla and is the thickest hair layer. It contains most of the hair's pigment, giving the hair its color. The major pigment in the cortex is melanin Melanin (; from el, μέλας, melas, black, dark) is a broad term for a group of natural pigments found in most organisms. Eumelanin is produced through a multistage chemical process known as melanogenesis, where the oxidation of the amin ..., which is also found in skin. The distribution of this pigment varies from animal to animal and person to person. In humans, the melanin is primarily denser nearer the cuticle whereas in animals, melanin is primarily denser nearer the medulla.James, William; Berger, Timothy; Elston, Dirk (2005) ''Andrews' Diseases of the Skin: Clinical Dermatology'' (10th ed.).

Medulla (hair)
The medulla is the innermost layer of the hair shaft. This nearly invisible layer is the most soft and fragile, and serves as the pith or marrow of the hair. Some mammals don't have a medulla in their hair. The presence or absence of this layer and the characteristics of the medulla can aid taxonomists in identifying what taxa a hair comes from. Characteristics include whether the medulla contains air pockets as well as the histology of the medulla. Scientists are still uncertain about the exact role A role (also rôle or social role) is a set of connected behaviors, rights, obligations, beliefs, and norms as conceptualized by people in a social situation. It is an expected or free or continuously changing behavior and may have a given indivi ... of the medulla, but they speculate that it is primarily an extension that is more prominent in depigmented (grey or white) hair .James, William; Berger, Timothy; Elston, Dirk (2005) ''Andrews' Diseases of the Skin: Clinical Dermatol ...

Keratin
Keratin () is one of a family of structural fibrous proteins also known as ''scleroproteins''. Alpha-keratin (α-keratin) is a type of keratin found in vertebrates. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. Excessive keratinization participate in fortification of certain tissues such as in horns of cattle and rhinos, and armadillos' osteoderm. The only other biological matter known to approximate the toughness of keratinized tissue is chitin. Keratin comes in two types, the primitive, softer forms found in all vertebrates and harder, derived forms found only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
