For a first time wig & hair system buyer, the industry terminology and definitions can be very confusing. When you start reading about hair systems and wigs online, you will come across many unfamiliar terms. That’s why we have put together this A to Z guide of hair system and wig terminology. We hope you find this glossary beneficial!
We will start by explaining what a hair system is as this is a new word and concept to many. To put it simply, hair system is a semi-permanent hair replacement solution which is attached to the scalp by tape or glue. Hair systems are mostly made with human hair and are designed to be undetectable and worn for days on end.
They are much more than your typical wigs and toupees. That said, you will find that hair systems, hairpieces, toupees and wigs are all used interchangeably in the hair industry.
Let’s begin with the wig terminology!
The part of the hair system which is attached to the scalp. The base is also what hair is attached to. It won’t be wrong to call it the cornerstone wig terminology.
It refers to the type of material that the hair system is made from. Materials range from lace to monofilaments and skin.
A biological film with a skin thickness between 0.08 and 0.12mm. Hair can be knotted or injected depending on thickness.
Knots are bleached to make wigs undetectable and to achieve a realistic look. They are particularly well-suited to the front hairline of a system.
It’s the name given to the process that attaches a hair system to the head with the help of tape or adhesive. Self-explanatory wig terminology this is!
Naturally straight and extremely strong. They are sleek but without a shiny doll-hair look. It ranges in color from off black to dark brown.
This wig terminology defines how we measure the number of strands of hair on a hair system. It is generally measured by counting the number of hair strands in one square inch (2.5cm). If someone has “thick” hair, then, they will have a high hair density.
It’s a way of knotting the hair to the base. Double knots are considered the strongest and most durable type of knot and widely used on integration systems and other big-holed base materials. That said, these are bigger and more visible than other knots.
Double split knots
Double split knots are stronger than single split knots (see below) but smaller than double knots. Read on for more wig terminology!
(Double Split Knotting)
European hair is considered to be the softest and finest of all hair types. It is unprocessed virgin hair with all its cuticles intact and hair in the same direction. It’s usually brown or blonde and is not available in shades of black.

Fine mono (filament)
It’s a durable man-made fiber that can support higher hair densities.
Fine welded mono (filament)
This wig terminology is known for its strength. It’s the strongest mono! It’s very durable and can support higher hair densities. Its holes are bigger than fine mono.
The most commonly used among all lace materials! Lightweight, delicate and virtually invisible on the scalp. French Lace is more durable than Swiss lace, and can support up to medium-heavy density hair.
It refers to the shape of your front hairline. Choosing a front contour will help you decide what type of hairline your hairpiece will have.
It’s made of lace or mono and can cover a PU perimeter to ensure a natural appearance to the front hairline.
Full cap wigs
These wigs are more commonly associated with women. These wigs cover the entire head of the wearer. A common wig terminology if you ask us!
Thick, very durable and can hold heavy densities but has a less natural appearance than other materials.
Glueless wigs are full cap wigs that can be secured to the head with adjustable straps or combs removing the need for tape or glue.

The standard hair choice in the industry. Smooth and soft texture. Genetically speaking, it is very similar to Caucasian hair.
Injected hair (flat)
Hair is injected into a usually thin skin base at an acute angle. It cannot be combed backward
Injected hair (lift)
Hair is injected into a usually thicker skin base at an obtuse angle and can be combed in any direction
A type of hair system designed to be worn on top of existing hair. It’s ideal for people with thinning hair. The wearer can pull their own hair through the holes of the netting base and let it blend with the hair of the integration system. Instantly gives more volume and can cover bald spots.
The general term for attaching hair to the base of a hair system (also see ventilation). Knotting does not necessarily mean the hair will have knots.
PU and poly are the names used to describe the transparent material that is often used around the perimeter of bases to give them added sturdiness and make the bonding process easier.
Human hair that has been gathered in such a way as to keep all its cuticles properly aligned in relation to its neighboring hair, therefore all the hair runs in the same direction. Used in higher-quality hair systems, this hair type is soft and silky.
When the lace or skin of a front hairline is cut in a zig-zag fashion to create a natural appearance. Must-know wig terminology for those opting for cut-in service.
Much thicker than other skin materials with a thickness around 0.5-1mm. Usually made with injected hair, it’s suitable for long and/or heavy density hair and can be made to any color.
Intricate and labor-intensive type of base design. Hair is knotted onto lace and a very fine layer of silk mono is attached to the underside of the lace which hides the knots. Silk tops are thicker types of bases but very natural in appearance.
Smaller (but weaker) than all other knots so single knots have a more natural appearance. Hair has a flat look to it.
Single split knots
Typically used at the front of lace or skin hair systems to give a natural and gradual hairline. Single split knots are stronger than single knots and smaller than double knots.
(Single Split Knotting)
The most commonly-used terminology to describe the polyurethane, a biological film used to make skin bases. The skin can have a thickness of between 0.03 and 0.12mm. Hair can be knotted or injected into the skin depending on the thickness.
Super Fine Mono (filament)
It has smaller holes than other fine mono materials making it more delicate. Not suited to high density hair.
Most natural, undetectable and breathable of all base materials. Invisible-like! It’s very fine and delicate, making it not a very durable material. Also, it can take no more than a light-medium hair density.
Hair is made from fine plastic filaments that have the look and feel of real hair. Requires little maintenance but should not be blow-dried.

The hair that is knotted to the underside of a PU perimeter to hide the PU and make the edge more natural.
The most natural of skin bases with a thickness of around 0.03-0.05mm. Hair strands are V-looped into the surface.
Another wig terminology used to describe the process of attaching hair to the base.
Hair that is pricked through a skin base and then pulled back through another hole to create a V-like appearance from a side view. No knots.
The raw hair from a donor’s head that has not been permed, colored or processed in any way.
