A-Z Wig Terms

A

Adjustable Straps. Two small Velcro tabs sewn into the inside back of almost every modern wig cap. By tightening or loosening the straps you can change the circumference of the cap by roughly 1 inch (2.5 cm), allowing the same wig to fit a variety of head sizes comfortably. Adjustable straps are the simplest way to get a secure feel without glue or tape, and they're particularly useful for first-time wearers who don't yet know their exact cap size. If a wig still slips after the straps are fully tightened, the cap is too large and a different size will be needed.

Alopecia Wig. A general label for wigs marketed to people with alopecia areata, alopecia universalis, traction alopecia or other forms of hair loss. There is no official "alopecia" cap construction, but the wigs commonly recommended for alopecia wearers share certain features: a soft, smooth interior lining (no scratchy wefts against the scalp), an adjustable or stretch cap to fit a fully bare head, and a hand-tied or monofilament parting that looks realistic when no biological hair frames the face. Many of our customers with alopecia choose lightweight synthetic styles for everyday wear and a human hair piece for special occasions.

B

Baby Hair. The fine, wispy hairs along the perimeter of a wig that mimic the soft regrowth around a natural hairline. Quality lace front and frontal wigs ship with pre-laid baby hair that can be slicked into shape with edge control gel. Baby hair softens the transition between lace and skin, making the hairline appear more realistic. If you're new to wigs, leave the baby hair as-is until you've watched a tutorial — over-styling can flatten or break these delicate strands.

Balayage. A French colouring technique where lighter shades are painted by hand onto darker base hair to create a soft, sun-kissed gradient. On wigs, balayage refers to a multi-tonal colour pattern (rather than a single flat shade) with subtle highlights running through the mid-lengths and ends. Balayage wigs photograph beautifully and look more realistic than block colours because real hair is rarely one uniform tone.

Bangs (Fringe). "Bangs" is the American word and "fringe" is the British word — both refer to a section of hair cut shorter and styled forward across the forehead. Wigs come with several bang styles: blunt (straight across), wispy (textured and feathered), side-swept (parted to one side) and curtain (long and parted in the middle). Bangs hide the hairline almost completely, which is why they're a popular first wig for anyone worried about lace exposure. Browse our wigs with bangs collection to see the most popular cuts.

Bob. A short to mid-length cut where the hair finishes between the chin and the shoulders, usually with a blunt or angled hemline. Classic bobs are jaw-length, long bobs (also called "lobs") sit at the collarbone, and chin-length French bobs feel especially modern. Bobs suit almost every face shape and are easy to maintain because there's less hair to brush, wash or store. See our bob wigs collection for synthetic and human hair options.

C

Cap Construction. The umbrella term for how a wig's base is built — and arguably the single most important feature to understand before buying. The four most common constructions are basic wefted (machine-stitched rows of hair, lightweight and affordable), monofilament (a fine mesh cap where each hair is hand-tied to mimic a real scalp), lace front (a sheer lace panel at the hairline for a natural look), and full lace (lace across the entire cap for full styling versatility). Many modern wigs combine constructions, for example a lace front with a monofilament parting. The construction affects price, comfort, breathability and how natural the wig appears. For a deeper look, read our wig types explained guide.

Cap Size. The internal circumference of the wig, measured in inches around the head. Standard women's wigs are roughly 21.5 inches, with petite (20–21 in) and large (22.5–23 in) options for smaller and larger heads. To find your size, wrap a soft tape measure around your hairline, behind your ears and over the nape. Most wigs have adjustable straps that give about an inch of flex either way. See our wig size guide UK for a full measurement walkthrough.

Combs. Small plastic or metal combs sewn into the inside of a wig cap (usually two at the front, one at the back, one at each side) that anchor the wig to your biological hair. Combs are the alternative to glue or tape for wearers who have some hair to grip onto. They take a few practices to position correctly, but once mastered they hold the wig firmly through everyday activities including walking, bending and gentle exercise.

Cuticle. The microscopic outer layer of a hair shaft, made up of overlapping scales. In premium human hair wigs, the cuticles are kept intact and aligned in the same direction (root to tip) — this is what makes Remy hair feel so smooth and tangle-free. Lower-grade human hair has the cuticles stripped or running in opposing directions, which feels coarser and tangles within weeks.

D

Density. How thick the hair is on the cap, expressed as a percentage. The most popular density for daily-wear wigs is 130%–150%, which mimics average natural hair. Lower densities (80%–110%) suit older customers and anyone who wants a delicate, sparse appearance, while higher densities (180%+) give the dramatic, full Hollywood look you see in red-carpet photos. A higher number is not automatically "better" — over-dense wigs can look wig-like and feel heavy in summer.

Drawstring. A length of cord threaded through the back of the cap (or, on some toppers, around the entire base) that you pull tight and tie like a shoelace. Drawstrings give a more customised fit than Velcro straps alone and are common on hair toppers, U-part wigs and headband wigs. They also let larger-cap wigs cinch down to fit petite heads.

E

Edges. A casual term for the fine baby hairs and the hairline along your temples. In the wig world, "laying your edges" means using gel and a small brush to swirl the baby hair on a lace front into a polished shape that blends into the skin. Edge control is especially important for textured and afro wigs where a sharp hairline can give the wig away.

F

Fibre. The material the wig hair is made from. Modern wigs use either real human hair (Remy, virgin or non-Remy) or one of several synthetic fibres including Kanekalon, Toyokalon, Futura and heat-friendly blends. Fibre choice determines how the wig looks, feels, holds its style, reacts to heat and how long it lasts before needing to be replaced. UK shoppers usually start with synthetic for affordability and ease, then graduate to human hair once they know what cap construction and length suit them best. For a side-by-side comparison of the major fibre types, see our wig types explained guide.

Frontal. A larger lace panel that covers the front hairline ear-to-ear (typically 13×4 or 13×6 inches), as opposed to a closure which covers a smaller central area. Frontals let you part the hair anywhere along the front and pull the hair back into ponytails or updos without exposing the cap. They're commonly used in the lace front wig category. Browse our lace front wigs collection to see frontals in action.

Full Lace. A wig where the entire cap is made of fine lace (rather than just the front), with each hair individually hand-tied to the mesh. Full lace wigs are the most versatile because you can part them anywhere and even style them into high ponytails. They're also the most expensive and the most delicate, so they're usually reserved for human hair pieces meant for special occasions or daily wear by experienced users.

G

Glue / Glueless. Adhesive products (liquid glue or wig tape) used to bond a lace front directly to the skin for the most invisible finish. "Glueless" wigs achieve a similar secure fit using combs, adjustable straps and silicone grips alone — no adhesive against the skin. Glueless wigs are kinder to sensitive skin, faster to put on and easier for beginners. Browse our glueless wigs collection if you'd rather skip the glue altogether.

H

Hand-Tied. A construction method where each individual hair is knotted to the cap by hand, rather than machine-sewn in rows. Hand-tied caps move more naturally with the head, feel softer against the scalp and look more realistic at the parting and crown. They take significantly longer to make — a fully hand-tied wig can be the work of several days for a single craftsperson — which is why hand-tied wigs sit in the premium price bracket. Many wigs use a hybrid approach: hand-tied at the parting and crown where it matters most, machine-wefted everywhere else for affordability.

HD Lace. "High Definition" lace — an ultra-thin, almost transparent lace that practically disappears against the skin once trimmed. HD lace is the latest evolution of lace front technology and produces the most undetectable hairline currently available on the market. It's more delicate than standard Swiss lace and tears more easily during installation, so it needs careful handling and is best reserved for special occasions or experienced wearers. The trade-off is genuine: HD lace can pass for skin in close-up photographs and on video, where standard lace sometimes still gives the wig away.

Headband Wig. A cap-style wig with no lace at the front, designed to be worn with a fabric or satin headband covering the hairline. Headband wigs are the easiest possible style to wear — slip on, adjust the headband, done — which makes them perfect for beginners, gym wear, holiday packing and anyone who hates fuss. See our headband wigs collection for our most popular textures.

Heat-Friendly Fibre. A modern synthetic fibre (often a Futura blend) that can withstand low-to-medium heat from straighteners, wands and curling tongs without melting. Heat-friendly synthetic wigs let you change the style at home, although you should always use the lowest temperature that works (around 150°C / 300°F) and never the heat settings you'd use on real hair, otherwise the fibre will frizz or fuse.

Human Hair. Real hair harvested from human donors, then sorted, washed and constructed into a wig. Human hair wigs can be coloured, heat-styled, washed and treated almost exactly like your own hair, and they typically last 12 months or more with daily wear. They cost more than synthetic and require more maintenance, but they remain the gold standard for realism. Browse our human hair wigs collection from £199.

K

Kanekalon. A premium synthetic wig fibre developed in Japan, characterised by a soft, silky texture and an excellent natural shine. Kanekalon holds a styled curl or wave indefinitely without needing heat, is colour-stable through repeated washing, and doesn't easily tangle even with daily wear. Most quality synthetic wigs in the UK market are made from a Kanekalon or Kanekalon-blend fibre, and any product page that mentions Kanekalon by name is signalling an above-entry-level synthetic. See our synthetic wigs collection for examples.

L

Lace Closure. A small lace panel (usually 4×4, 5×5 or 6×6 inches) hand-tied with hair, sewn into the top-front of a wig to create a realistic parting in one specific spot. Closures are simpler and cheaper than frontals because they cover less area, but they don't offer the same parting flexibility. Closures are ideal if you always wear a centre or single side parting in the same place.

Lace Front. A thin, sheer lace panel sewn along the front hairline of the wig, with hair individually hand-tied to the mesh. When the lace is trimmed and pressed against the skin, it creates the illusion that hair is growing directly out of the scalp — there's no hard edge, no visible cap. Lace front is the single most popular construction for natural-looking wigs and the reason most modern wigs are nearly impossible to spot. Browse our lace front wigs collection to compare options.

Length. Always measured in inches, from the cap (or your hairline) to the tip of the longest hair, when the hair is straight and uncurled. Common length brackets are short (6–10 in / pixie to chin), medium (12–16 in / shoulder), long (18–22 in / bra strap) and extra long (24 in+). Note that curly and wavy wigs always look 2–4 inches shorter than the listed measurement once the texture springs up. For the easiest styles to wear, see our short wigs collection.

M

Machine-Made. A wig where the hair is sewn onto the cap by sewing machine in long horizontal strips (called wefts). Machine-made wigs are the fastest to produce, the most affordable and the most durable, but the parting and hairline aren't as realistic as hand-tied or lace-front constructions. Most synthetic wigs under £80 are machine-made, and that's perfectly fine for everyday wear with bangs or longer parting hair to disguise the wefts.

Monofilament. A fine, breathable mesh material used in the crown or top section of premium wigs, with each hair individually hand-tied to the mesh. Looking down at a monofilament parting, you can see what appears to be a real scalp showing through — there's no visible track of hair, no hard edge. Monofilament is the gold standard for realistic partings and is especially popular with medical hair loss customers because it's gentle on a sensitive scalp. Browse our monofilament wigs collection.

N

Natural Hairline. A wig hairline that has been pre-plucked and styled to look like a real, slightly irregular hairline — not the perfectly straight, dense, almost cartoon-like hairline you'd see on a cheap costume wig. A natural hairline has subtle variation in density, soft baby hairs at the temples, and follows the curve of an actual human forehead. Most modern lace front wigs ship with a pre-plucked, baby-haired natural hairline ready to wear straight from the box, but cheaper wigs may need a few minutes of plucking with tweezers to achieve the same effect.

Nape. The back of the neck, where a wig finishes. A well-fitted wig sits flat against the nape without gaping or lifting when you turn your head, and the hair at the nape blends softly into the natural curve of the neck. If your wig pulls away from the nape, the cap is too large or the adjustable straps need tightening; if the nape feels uncomfortably tight, the cap is too small for your head shape and a larger size is in order. Nape comfort is one of the most overlooked fit factors in first-time wig buyers.

O

Ombre. A two-tone colour effect where the roots are deliberately darker than the lengths, creating a smooth gradient from one shade to another. The most common ombre is dark brown roots fading into honey or caramel tips, but ombres come in every colour combination from natural to fantasy. Ombre wigs look more realistic than block colours because real hair is almost never one uniform tone.

P

Parting. The line where the hair is split on top of the head — centre, side or zigzag. Wigs with a free or hand-tied parting let you change the parting position; wigs with a fixed parting (sewn or pressed in place) only look natural in one spot. Always check the product description for parting type before you buy if you're particular about where your hair separates.

Permatease. A lightweight backing of pre-teased synthetic fibre added to the underside of short, voluminous styles to give them lift and body without adding weight or bulk. Permatease is what makes a short, layered synthetic wig hold its bouffant shape all day without flat spots developing where you've slept on it or worn a hat. It's completely invisible from the outside and doesn't add any uncomfortable bulk against the scalp, which is why it's a favourite for older customers who want voluminous short styles without the heat of a heavier cap.

Pre-Plucked. A wig hairline that has been hand-plucked at the factory to remove the dense, uniform line of hair you'd otherwise see along the lace edge — leaving a softer, more irregular and far more realistic hairline behind. Pre-plucked wigs save you the work (and the risk of damaging the lace) of plucking your own with tweezers, and they're ready to wear out of the box. Almost all good lace front wigs from reputable brands now ship pre-plucked, but it's still worth checking the product description, because some entry-level wigs skip this step.

R

Ratio. Sometimes called "hair ratio", this is shorthand for how many bundles or strands of hair are used to make the wig. A higher ratio means a denser, fuller wig with more hair on the cap. Ratio is a manufacturer's specification and is more commonly seen in industry catalogues and B2B documents than on retail product pages, which is why most UK shoppers don't need to know it. The simpler "density %" measurement does the same job in a way that's easier to compare across brands.

Remy Hair. Human hair where the cuticles have been kept intact and aligned in the same direction (root-to-tip) during processing. Remy hair feels noticeably smoother to the touch, tangles far less even after months of wear, and lasts significantly longer than non-Remy hair where the cuticles have been stripped or run in opposing directions. When buying human hair wigs, "Remy" is a quality marker worth paying for, especially if you plan to wash and style the wig regularly. See our human hair wigs collection for Remy options.

S

Silk Top. A premium parting construction where a layer of fine silk fabric sits beneath the hand-tied lace, creating the convincing illusion of a real scalp showing through the parting. Silk tops are even more realistic than standard monofilament partings because the colour and texture of the silk closely match real skin tones, hiding the small knots that would otherwise be visible at the root of each hair. They're typically found on luxury human hair wigs and on premium monofilament wigs, and they add £50–£200 to the price compared to a standard mono top.

Stocking Cap. A close-fitting nylon or mesh cap worn under a wig to flatten your biological hair and protect both the scalp and the wig. Stocking caps come in skin tones to blend in if any cap shows. They're optional but recommended if you have a lot of biological hair to tuck away or if you want extra grip under a glueless wig.

Synthetic. Wig hair made from man-made fibres (Kanekalon, Toyokalon, Futura and others) rather than human hair. Modern synthetics look remarkably realistic, hold their style indefinitely without restyling, and cost a fraction of human hair. The trade-offs are a shorter lifespan (3–6 months of daily wear), limited heat styling, and the need to replace rather than restyle as the fibre wears. See our synthetic wigs collection from £33.

Swiss Lace. A delicate, very fine lace material used in higher-end lace front wigs, prized for being almost undetectable against the skin once trimmed and pressed flat. Swiss lace is more fragile than the cheaper, sturdier French lace, so it tears more easily during installation and removal — but it disappears far better against the scalp once trimmed, which is why experienced wearers will pay the premium. HD lace is the next generation up from Swiss lace and offers an even thinner, more transparent finish for special occasions and high-resolution photography.

T

Topper. A partial hairpiece that clips onto the top of the head to add coverage, volume and length where natural hair is thinning — without the commitment of a full wig. Toppers are popular with women experiencing female pattern hair loss, postpartum shedding or thinning at the parting. They blend with your own hair around the sides and back, which makes them feel less hot and less obvious than a full wig. Browse our hair toppers collection for clip-in options.

Toupee. A small hair piece designed to cover specific areas of hair loss, traditionally associated with men but available for any wearer regardless of gender. Modern toupees use lace bases, hand-tied human hair and pre-styled hairlines, so they're a world away from the chunky, obvious toupees of decades past. A well-fitted modern toupee can be virtually invisible even in close-up — the technology has advanced enormously in the last fifteen years and is now closer to a partial lace front wig than the rigid hairpieces older shoppers may remember.

Tracks (Wefts). The horizontal strips of hair sewn into a machine-made wig cap, typically running ear-to-ear in stacked rows. You'll sometimes see tracks referenced when comparing constructions: a fully hand-tied wig has no tracks at all, a machine-made wig is built entirely from tracks, and many wigs use a mix — hand-tied at the parting and crown for realism, machine-wefted everywhere else for affordability and durability. The word "weft" is used interchangeably with "track" by most UK retailers.

U

U-Part. A wig with a U-shaped opening at the front-top of the cap, designed so you can pull a section of your own biological hair through the opening to blend with the wig. U-part wigs are the most natural-looking option for women with healthy biological hair because there's no lace or wig material at the parting — only your real hair. They take a few extra minutes to install but the result is virtually undetectable.

V

Virgin Hair. Human hair that has never been chemically processed — never coloured, never permed, never bleached. Virgin hair is the highest grade you can buy because the cuticles are completely intact and the hair retains its natural strength. Virgin hair wigs are the most expensive in our human hair range and typically last the longest. Browse our human hair wigs for premium options.

Ventilating. The hand-tying technique where individual hairs are knotted onto the cap one strand at a time. "Ventilating" is the craft term for what you might also see called "hand-tied" — the words are often used interchangeably. The skill matters: a well-ventilated wig has tiny, almost invisible knots, while a poorly ventilated one has chunky knots that show through the lace.

W

Wefted. A wig (or a section of a wig) built from machine-sewn strips of hair — see "Tracks" above. Wefted constructions are durable, lightweight and the most affordable, which is why basic wefted caps remain the most popular choice for everyday synthetic wigs at the under-£60 price point. The trade-off is that the wefts can be visible if you part the hair in an unusual place or pull it back tightly, so wefted wigs work best worn loose with bangs or longer parting hair to disguise the rows.

Wig Cap (the wig itself). The base of the wig — the part that actually touches the scalp, made from a combination of mesh, lace, silicone strips, breathable cotton and elastic depending on the construction type. The cap is what determines comfort, fit, breathability, weight and how securely the wig stays in place during the day. Spending a few extra pounds on a better cap is almost always worth it: the difference between a £33 basic cap and a £150 hand-tied monofilament cap is enormous in terms of how the wig feels after eight hours of wear.

Wig Cap (the liner). Confusingly, "wig cap" also refers to the thin nylon or stocking cap you can wear underneath a wig to flatten your biological hair and protect both the scalp and the inside of the wig. Context usually makes the meaning clear, but if a product description mentions a wig cap as a free accessory, this is almost always what's meant rather than a spare wig base. See also the entry for "Stocking Cap" further up the glossary.

Wig Tape. Double-sided medical-grade tape strips that hold a lace front securely against the skin for several days at a time. Wig tape is an alternative to liquid glue and is preferred by many wearers because it's faster to apply, easier to remove and noticeably gentler on the skin around the temples and hairline. Tape lasts about a week with normal wear before needing to be reapplied, and it's the recommended starting point for anyone new to bonded lace front wigs because there's almost no learning curve compared to liquid adhesive.

Y

Yaki. A texture name (originally meaning "permed" in Japanese) used to describe synthetic or human hair that mimics the look and feel of relaxed Afro-Caribbean hair. Yaki textures range from "Light Yaki" (similar to blow-dried natural hair) to "Kinky Yaki" (tightly textured). Yaki wigs are popular among Black women looking for natural-looking hair without the daily styling routine of relaxed real hair. For curly textures see our curly wigs collection.

FAQs

What are the most common wig terms a first-time buyer should know?

The five terms you absolutely need before your first purchase are cap construction (the way the wig is built), fibre (synthetic or human hair), cap size (the measurement around your head), density (how thick the hair is) and lace front (the most popular hairline construction). If you understand those five, you can read 90% of UK wig product descriptions with confidence. The rest of the glossary you can pick up over time as you discover what you like.

What is the difference between synthetic and human hair wigs in one line?

Synthetic wigs hold their style without effort and cost less, while human hair wigs feel and behave like real hair and last much longer — so synthetic is the easier choice for daily wear and human hair is the more versatile choice for styling freedom and long-term value.

What is a lace front wig?

A lace front wig has a thin, sheer lace panel sewn along the front hairline, with hair individually hand-tied to the mesh. Once the lace is trimmed and pressed against the skin, it creates the illusion that the hair is growing directly out of the scalp, with no visible cap edge. Lace front is the most popular construction in modern wigs and the reason that today's wigs are nearly impossible to spot when worn correctly.

What does wig density mean?

Density is how thick the hair is on the wig cap, expressed as a percentage. Average natural-hair density is around 130%–150%, which is also the most popular for daily wear. Lower densities (80%–110%) suit older customers and a delicate look, while higher densities (180%+) give the dramatic, glamorous Hollywood appearance. Higher density isn't always better — over-dense wigs can look obviously wig-like and feel heavy in summer.

What is wig cap size and how do I measure mine?

Cap size is the internal circumference of the wig, measured in inches around the head. Most women's wigs are a "Standard" size of about 21.5 inches, with petite (20–21 in) and large (22.5–23 in) options for smaller and larger heads. To measure your own head, wrap a soft tape measure around your hairline, just above your ears and round the nape of your neck. Most wigs include adjustable straps for about an inch of flex either way.
