Artificial nails, also known as fake nails, false nails, acrylic nails, press ons, nail extensions or nail enhancements, are extensions placed over fingernails as fashion accessories. Many artificial nail designs attempt to mimic the appearance of real fingernails as closely as possible, while others may deliberately stray in favor of an artistic look.
Artificial nails require regular upkeep: it is recommended that they are attended to, on average, every two weeks; however they may last over one month. [1] Nonetheless, their versatility in terms of shape, size, design and comparatively high durability are some advantages they hold over other types of manicures.
Artificial nails are an extension, not a replacement, of natural nails. There are two main approaches to creating artificial nails – tips and forms:
Atop these, either acrylic, hard gel, or any combination of both may be applied. Tips are available in many different designs, ranging from solid colors like gel or regular nail polish, to graphic designs such as animal prints and metallic colors. In addition to polishes, other embellishments may be used, such as rhinestones, glitter, stickers, fimo charms and striping tape, to add more to the artificial nail's design. Artificial nails can be shaped, cut, and filed into a variety of shapes, including square, squared oval/"squoval", rounded, almond, ballerina/coffin, mountain peak, lipstick, and stiletto.
Acrylic nails are made out of acrylic glass (such as, PMMA). The conventional technology employs polymer beads synthesized from ethyl methacrylate (poly-EMA). When it is mixed with a liquid monomer (usually ethyl methacrylate mixed with some inhibitor) it forms a malleable bead. This mixture begins to cure immediately, continuing until completely solid in minutes. [2] Acrylic nails can last up to 21 days but can last longer with touch-ups. [3] To give acrylic nails color, gel polish, nail polish, and dip powders can be applied. Use of MMA (Methyl methacrylate liquid monomers) acrylics are strongly discouraged and banned in some states as it can cause damage to the natural nail, asthma; irritated eyes, skin, nose, and mouth; difficulty concentrating; loss of smell and kidney issues. [4] A suitable alternative is EMA (Ethyl Methacrylate Liquid Monomers) in salon use.
Gel nails can be utilised in order to create artificial nail extensions, but can also be used like nail polish. They are hardened using ultraviolet light. [5] They last longer than regular nail polish and chip less often. They can have a high-gloss finish and last for two to three weeks. [6] [5]
Gel nails are strong, although not as strong as acrylic or fiberglass nails, and tend to be more expensive. [5]
There use of the ultraviolet light in the application of gel and other types of nails contributes to melanoma of the nail bed. This is not often discussed during the application of the nails.
Acetone does not dissolve some types of gel nails, so they have to be removed at a salon by buffing and filing, usually with an electric nail file. [5] Repeated buffing can lead to thinning of the nail plate. [7] Improper application of Gel-X, and similar artificial nail systems that imitate Gel-X, can lead to fungal infections and allergic reactions.
A new gel nail extension was created circa 2017 that is commonly referred to as Gel-X, or soft gel tips. [8] It is a soft gel nail tip that is precut in differing styles and lengths which covers the whole nail bed up to the end of the nail. Gel-X are plied by first applying a PH bonder (dehydrator) followed by an acid-free gel primer. Finally, it is glued on using a gel adhesive that is cured using a [8] UV light. The removal process of gel-X nails is dissolving in acetone for 20 minutes. [9]
Nail wraps are formed by cutting pieces of fiberglass, linen, silk fabric, or another material to fit on the surface of the nail (or a tip attached prior), to be sealed onto the nail plate with a layer of resin or glue. They do not damage the nail and also provide strength to the nail but are not used to lengthen it [10] – and they can also be used to fix broken nails. [10] The treatment is, however, more expensive. [10] Nail wraps last 5–7 days, but can last longer if worn and used correctly. Add-ons can impact the durability of the nail wraps.[ citation needed ] To take nail wraps off correctly, the wrap should be soaked in acetone for long enough to soften the adhesive.
Nail tips are made of a strong bendable material called acrylonitrile butadiene styrene (ABS). Nail tips are attached to the natural nail to extend its length and provides room for more nail designs. [11] They can come in many different shapes, sizes, and colors, but the most popular ones are usually clear or white. They only last for 7–10 days. [11]
Some nail tips can also be made out of soft gel, for stronger applications when tips are the sole extension, with no other product on top. Gel-X is an example of a soft gel nail tip system.
With the dip powder method, a clear liquid is brushed onto a nail and the nail is then placed into clear, shimmery or pigmented dip powder, similar to what is used in the application of acrylic nails. The process is repeated multiple times, depending on how long the extension is. [12] Dip nails tend to last about a month, two-to-three weeks longer than gel and acrylic nails. [13] It can be worn on natural nails, nails with added tips, or can create artificial nails. Dip-powder nails do not require any UV/LED light to cure: instead they are cured using an activator.[ citation needed ] The quickest way to remove dip powder is to drill, clip off or buff out layers of the powder so that, when they are soaked in acetone, they simply slide off. [14]
Historically, artificial nails were common symbols of status all across the world:
"The earliest experiments and resultant artificial nails used a monomer and polymer mix applied to the nail and extended over a supporting form. This structure hardened and, when the support was removed, was then shaped to look like a natural extension of the nail plate. These dental materials were chemicals that came under the 'family' name of acrylics: thus the acrylic artificial nail was created. All materials subsequently used also belong to the acrylic family, but the term 'acrylic nails' has stuck to the method of using a liquid monomer and powder polymer." [15]
In 1878, Mary E. Cobb opened the first manicure salon in Manhattan. This came after studying nail care in France and marrying podiatrist, J. Parker Pray. [16] During the 1920s, short well-manicured round nails were a symbol of wealth. [16] Revlon made their first appearance in 1932 with only one single product, long lasting formula nail enamel. [16]
In 1954, Dr. Fred Slack Jr., a dentist, cut his thumb nail at work, and created an artificial nail using dental acrylic resin and aluminum foil as a realistic-looking temporary replacement. After experiments with different materials to perfect his invention, he and his brother, Tom, patented a successful version and started the company Patti Nails. Fred Slack used his dental equipment and chemicals to replace his natural nail, but over time the process has significantly changed. [17]
In the late 20th century, artificial nails for women became widely popular all over the world. In today's time there are even nail styling competitions. Judges of these nail competitions look for consistency from nail to nail. They also judge whether or not the nails complement the model's hands. If the nails are beautiful, but too long for the model's hands, the judge will count off points. The competitors will be judged on how neat their work space is and how organized they are.[ citation needed ]
Acrylic nails help conceal or fix broken, damaged, short, or otherwise considered "undesirable" nail appearance. They also help prevent nail biting, breakage, and splits. They are used when people are not able to grow the length and strength of natural nails that they desire or simply desire a new fashion look. This problem can be solved by using certain nail techniques such as nail tipping, sculptured nails, nail wrapping, or acrylic overlays. With improper removal, acrylic nails often damage natural nails. An experienced nail technician should assist with this to ensure nail health.
If fitted properly, artificial nails are usually not problematic. However, long term use and poorly fitted nails can seriously damage the nail bed and hamper natural nail growth. Natural nails may become thin and weaken with frequent touch-ups. The most common problem associated with artificial nails is a fungal infection that may develop between the false and natural nails.
When artificial nails are applied to the natural nail surface, minor types of trauma to the artificial nails which can happen from something as harmless as scraping or bumping a nail against a firm surface can cause separation of the nail from its nail bed. This allows bacteria and fungus to potentially enter the separated area setting up an infection and bacterial burden. Many hospitals and healthcare facilities do not allow employees to have long fingernails, fake or real, due to the risk of said nails harboring microbes that could transmit diseases to patients. [18] Infection can also be a risk when nails are applied by a disreputable nail salon that does not follow sanitary practices. [19]
The use of nail polish and artificial nails make proper hand hygiene and hand washing more difficult, because they are more difficult to clean than natural nails. Therefore, in professions where hand hygiene is important, such as when handling food or providing patient care, nail polish and artificial nails are usually forbidden. For example, a guideline of the National Health Service (England) explicitly forbids both during patient care activity. [20] The Food and Agriculture Organization publishes similar advice for the food retail sector. [21]
From an occupational health standpoint, there could be hazards to nail salon workers who are exposed to the chemical fumes from artificial nails during their entire work shift. Ethyl methacrylate can be used for artificial nails and can cause contact dermatitis, asthma, and allergies in the eyes and nose. [22] Nail salon workers also face exposure to other chemicals used, such as toluene, dibutyl phthalate, and formaldehyde. [23] [24] [25] The products used to make acrylic nails may also be flammable. [26]
Exposure to methyl methacrylate (the precursor to acrylic glass) can cause drowsiness, light-headedness, and trembling of the hands, [27] and so it has been banned for use in cosmetology in the majority of US states. [28] Use of methyl methacrylate can cause skin reactions and damages to the natural nails, sometimes even permanently. Some signs that a nail salon is still using MMA might be prices that are significantly lower than most other nail salons. [29] There will be an unusually strong and fruity odor. Also, the manicurist will often be wearing a mask to keep from breathing in the harmful chemical. [27] Removal is much more difficult, and drills are more excessively used. Ethyl methacrylate is the safer alternative for MMA, but it costs several times as much and can still produce many effects.
A monomer is a molecule that can react together with other monomer molecules to form a larger polymer chain or three-dimensional network in a process called polymerization.
Cyanoacrylates are a family of strong fast-acting adhesives with industrial, medical, and household uses. They are derived from ethyl cyanoacrylate and related esters. The cyanoacrylate group in the monomer rapidly polymerizes in the presence of water to form long, strong chains.
Butanone, also known as methyl ethyl ketone (MEK) or ethyl methyl ketone, is an organic compound with the formula CH3C(O)CH2CH3. This colorless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts. It is partially soluble in water, and is commonly used as an industrial solvent. It is an isomer of another solvent, tetrahydrofuran.
Poly(methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others. This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes.
A manicure is a mostly cosmetic beauty treatment for the fingernails and hands performed at home or in a nail salon. A manicure usually consists of filing and shaping the free edge of nails, pushing and clipping any nonliving tissue at the cuticle and removing hangnails, treatments with various liquids, massage of the hand, and the application of fingernail polish. When the same is applied to the toenails and feet, the treatment is referred to as a pedicure. Together, the treatments may be known as a mani-pedi.
A nail is a protective plate characteristically found at the tip of the digits of all primates, corresponding to the claws in other tetrapod animals. Fingernails and toenails are made of a tough rigid protein called alpha-keratin, a polymer also found in the claws, hooves and horns of vertebrates.
A pedicure is a cosmetic treatment of the feet and toenails, analogous to a manicure.
Nail polish is a lacquer that can be applied to the human fingernails or toenails to decorate and protect the nail plates. The formula has been revised repeatedly to enhance its decorative properties, to be safer for the consumer to use, and to suppress cracking or peeling. Nail polish consists of a mix of an organic polymer and several other components that give it colors and textures. Nail polishes come in all color shades and play a significant part in manicures and pedicures.
Methyl methacrylate (MMA) is an organic compound with the formula CH2=C(CH3)COOCH3. This colorless liquid, the methyl ester of methacrylic acid (MAA), is a monomer produced on a large scale for the production of poly(methyl methacrylate) (PMMA).
Ethyl formate is an ester formed when ethanol reacts with formic acid. Ethyl formate has the characteristic smell of rum and is partially responsible for the flavor of raspberries, occurring naturally in some plant oils, fruits, and juices. Ethyl formate does not occur naturally in the animal kingdom.
Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH2=C(CH3)CO2H. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents. Methacrylic acid is produced industrially on a large scale as a precursor to its esters, especially methyl methacrylate (MMA), and to poly(methyl methacrylate) (PMMA).
2-Ethoxyethanol, also known by the trademark Ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate.
Synthetic resins are industrially produced resins, typically viscous substances that convert into rigid polymers by the process of curing. In order to undergo curing, resins typically contain reactive end groups, such as acrylates or epoxides. Some synthetic resins have properties similar to natural plant resins, but many do not.
Ethyl acrylate is an organic compound with the formula CH2CHCO2CH2CH3. It is the ethyl ester of acrylic acid. It is a colourless liquid with a characteristic acrid odor. It is mainly produced for paints, textiles, and non-woven fibers. It is also a reagent in the synthesis of various pharmaceutical intermediates.
Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic. It liberates hydrogen cyanide easily, so it is used as a source of such. For this reason, this cyanohydrin is also highly toxic.
A nail salon or nail bar is a specialty beauty salon establishment that primarily offers nail care services such as manicures, pedicures, and nail enhancements. Often, nail salons also offer skin care services. Manicures are also offered by general beauty salons, spas, and hotels. People who work at nail salons are usually called nail technicians, manicurists, or nailists.
A nail technician or nail stylist is a person whose occupation is to style and shape a person's nails. This is achieved using a combination of decorating nails with coloured varnish, transfers, gems or glitter. Basic treatments include manicures and pedicures, as well as cleaning and filing nails and applying overlays or extensions.
A glass nail file is a nail file with an abrasive surface made of glass, that is used to gently grind down and shape the edges of fingernails. They are often used in manicures and pedicures after the nail has been trimmed using nail clippers.
Water marble nails are a finger nail art technique involving dropping nail lacquers into clear water and creating a pattern on the water surface; the pattern is then transferred to the nails.
Nail art is a creative way to paint, decorate, enhance, and embellish nails. It is a type of artwork that can be done on fingernails and toenails, usually after manicures or pedicures.
