If you’re new to the world of hair systems then it could be easy to get lost in all the terminology. Do you know your Chinese hair from your Indian hair for example? Or how about all the different ways in which hair can be attached to your system?


It’s with that in mind that we thought we would put together a glossary with all the key terms you’ll need to make your shopping experience a smoother process.


Base material

Refers to the type of material that the hair system is made from. Materials range from lace to monofilaments to skin.


BIO  skin

A biological film with a skin thickness between 0.08 and 0.12mm. Hair can be knotted or injected depending on thickness.


Bleached knots

Knots are bleached to make them undetectable to achieve a realistic look. Particularly well-suited to the front hairline of a system.      


Chinese hair

Naturally straight and extremely strong. Sleek but without a shiny doll hair look. Ranges in color from off black to dark brown. 


Double knotting

When hair is double knotted onto the base material with a tiny hook. Considered the strongest and most durable type of knot and widely used on integration systems and other big-holed base materials. Bigger and more visible than other knots.

Double split knotting

When hair is double knotted on the base material with a tiny hook. Stronger than single split knots but smaller than double knots.

European hair

Considered to be the softest and finest of all hair types. It is non-processed virgin hair with all its cuticles intact and hair in the same direction. Feels particularly silky and sleek. European hair is usually brown or blonde and is not available in shades of black.


Fine mono(filament)

Durable man-made fiber that can support higher hair densities.    


Fine welded mono(filament)

The strongest mono. Very durable and can support higher hair densities. Its holes are bigger than fine mono.


French lace

The most commonly used among all lace materials. Lightweight, delicate and virtually invisible on the scalp. More durable than Swiss lace. Can support hair of a medium heavy density.


Front contour

Refers to the shape of your front hairline


Folded front

Made of lace or mono and can cover a PU perimeter to ensure a natural appearance to the front hairline


German net

Thick, very durable and can hold heavy densities but has a less natural appearance than other materials


Hair cutting

Systems can be cut and styled before being sent out making them ready to wear immediately


Hair density

The number  of strands of hair on a head. 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.


Indian hair

Standard choice in the industry. Smooth and soft texture. Genetically speaking, very similar to Caucasian hair.   


Injected hair (flat)

Hair is injected into a usually thin skin base at an acute angle and cannot be combed backwards       


Injected hair (lift)

Hair is injected into a usually thicker skin base at an obtuse angle and can be combed in any direction


Integrations systems

Different from other hair systems in that they are designed to be worn on top of existing hair. Hair is attached to a netting allowing the wearer to pull through their existing hair to give it more volume or to cover bald spots.


Polyurethane (PU)

A type of plastic that is often used for the perimeters of bases to give them added sturdiness


Remy hair

Human hair that has been gathered in such a way as to keep all its cuticles properly aligned in relation to its neighboring hairs, therefore all the hair runs in the same direction. Used in higher-quality hair systems. Hair is soft and silky.


Scallop front

When the lace or skin of a front hairline is cut in a zig-zag fashion to create a natural appearance


Silicon skin

Much thicker than other skin materials with a thickness around 0.5-1mm. Usually made with injected hair. Suitable for long and/or heavy density hair and can be made to any color.


Single knotting

Where hair is hand-knotted on the base with a tiny hook. Smaller (but weaker) than all other knots therefore producing a more natural appearance. Hair has a flat look.

Single knotting

Single split knotting

Where hair is knotted by hand on the base material (usually lace or skin hair systems) with a tiny hook. Usually used at the front to give a natural and gradual hairline. 

Single split knotting

Super fine Mono(filament)

Has smaller holes than other fine mono materials making it more delicate. Not suited to high density hair.


Swiss lace

Most natural, undetectable and breathable of all base materials. Very fine and delicate so not as durable as other bases. Can take light medium hair density as its maximum.


Synthetic hair

Hair made from fine plastic filaments that has the look and feel of real hair. Requires little maintenance. Should not be blow-dried.


Ultra thin skin

The most natural of skin bases. This plastic wrap like material has a skin thickness of around 0.03-0.05mm. Hair strands are V-looped into the surface.


V-looped hair

Hair that is pricked through the skin base and then pulled back through another hole to create a V-like appearance from a side view. No knots.


Virgin hair

The raw hair from a donor’s head that has not been permed, colored or processed in any way.
