Wig Cap Types & Construction

Here’s a look at the commonly seen wig types, including what the caps are made of and what each type offers. A wig has many uses. For example, in film, TV and theatre, wigs are used to create characters, change the perceived age of someone or provide the right hair for period styles. Wigs can also be used everyday to cover baldness or thin hair, or simply for fun, fashion and fancy dress.

Wigs consist of two main parts, namely the cap or foundation and the hair.

A wig cap is simply the foundation of any wig. It is the base material into which the hair is attached. It also creates the wig’s head-like shape and it is used to attach the wig to the wearer’s head.

The hair in a wig can be real (human or animal) or made from synthetic hair. To attach the hair to the wig foundation, it is either hand-tied or machine sewn on. This all depends on what sort of wig is being made.

Other features of a wig can include:

  • Mass produced wigs often have plastic-coated tape tabs for double-sided tape (toupee tape) to be used. This allows the wig to be secured to the head.
  • Wigs usually have an adjustable strap and hooks or a Velcro strap at the nape. This is used to fine-tune fitting at the back of the head.
  • Wigs may have tiny toupee or wig clips sewn into them. These slide into a small section of the wearer’s hair for extra security.

Types of Wig Cap or Foundation

Hair Lace Foundation

  • Hair lace is a fine sheer material that comes in different thicknesses and colours from light to dark. This enables a wig maker to match someone’s skin tone. The mesh has a tiny honeycomb structure, and the hair is hand knotted onto this.
  • Lace is measured in denier (just like stockings). Lace used for film/TV is 20 or 30 denier. Lace for HD is even finer, making it very easy to tear and it needs handling very delicately. Wigs for theatre are made with thicker lace, as it is more durable and robust.
  • Hair lace is used where a more natural looking wig is required, especially on the front hairline, as there isn’t a hard edge. The front lace goes onto the wearer’s forehead and should blend into the skin. This should not be noticeable on camera, stage or even to the eye for the finer laces.
  • Wigs made completely with a hair lace foundation is called a hair lace wig. A wig that is made with a solid edge instead, is known as a hard-front wig. It is also possible to just use hair lace at the front of a wig.
  • A custom-made hair lace wig is the most expensive type of wig you can buy.

Monofilament Cap

  • Monofilament is a very fine, lightweight and smooth mesh fabric. It is also transparent, which allows the wearer’s skin colour to show through it, creating a more natural finish to the wig.
  • The monofilament can have either human or synthetic hairs used on it. The hair is usually hand-tied into the fabric, which allow the hair strands to move more freely.
  • Monofilament material can be used to make a whole wig, though it is more likely to just be used in key areas where the hair’s movement is more noticeable, like the crown or the parting. The rest of the wig can either be made from a wefted cap or a hand-tied foundation.
  • Wigs with a monofilament element are generally more natural looking than 100% wefted wigs. This is because the hair on a mono section appears to be growing out of the scalp. Likewise, the hair can be parted and combed in any direction.
  • A monofilament crown (mono crown) creates the appearance of natural hair growth at the crown area. 
  • The monofilament top (mono top) allows for parting in any direction and gives the most opportunity for styling flexibility.
  • monofilament parting (mono part) allows for multi-directional parting while creating the appearance of natural hair growth.

Wefted Cap

  • A wefted cap is made from rows of thin cotton or lace ribbons that have wefts of hair sewn onto them. These ribbons are then machine-sewn together to form the wig cap shape. Hence, they are also known as machine-made wigs.
  • The ribbons are flexible and reasonably stretchy, allowing them to comfortably fit the wearer’s head.
  • It is a lightweight and breathable cap because of the spaces between the wefts.
  • It is a very commonly used cap foundation. Hence it can also be known as a “standard wig” or a “classic cap”. Wefted wigs that don’t have a solid lace area at the top of the cap are also known as capless wigs.
  • A monofilament insert can be used with wefted wigs. This is usually along the top, the parting or the crown, which would then allow the wearer to part and brush the hair in any direction.
  • A hair lace front can also be added to a wefted cap, creating a softer more natural-looking front to the wig.

Types of Hair Used in Wigs

Wigs are mainly made from either human hair or synthetic fibre. Horse hair, crepe hair and yak hair can also be used for certain types of wigs. For example, judges’ wigs are made from horsehair.

Hair also comes in varying quality. There is good quality real hair and synthetic fibres, as much as there are cheaper options. Of course, this impacts on the look, durability and feel of a wig.  

Human Hair

  • Human hair for wigs comes from various places, mainly Europe (Spain, Italy and western Russia are common places) and Asia (India and China).
  • The hair needs to be processed, which weakens the structure and can make it porous. Asian hair in particular needs a lot of processing, as it needs to be lightened in order to be coloured.
  • Hair also no longer has a natural supply of oil, and it can become very dry with use over time. It needs caring for to preserve it and keep it from drying out and breaking.
  • It can be washed in shampoo and conditioned, is set and styled just like real hair is. It is also affected by heat, rain and humidity. It may not, however, behave exactly like hair on our heads due to the lack of natural oils and the processing it goes through to be ready for wig making.
  • Remy hair refers to hair that still has its cuticle and is sewn into wigs in the same direction as natural hair would grow. It is good quality hair and, therefore, is more expensively priced than hair that is stripped of its cuticle. A lot of hair used in the hair trade has been stripped of its cuticle.

Synthetic Hair

  • Manmade fibres are used to make synthetic hair and is designed to give the overall appearance and feel of real hair. Good quality synthetic hair can be difficult to distinguish from real hair and can have benefits over poor quality human hair. 
  • Synthetic fibre is cheaper to produce than human hair. It can be made in any colour or length, and can be made straight, waved or curly.
  • Synthetics can look less realistic than hair, especially the cheap synthetics. For instance, it can be very shiny. For the media, synthetic wigs are used for theatre productions or for background artists in film/TV, where close ups are not an issue.
  • Synthetic hair cannot be coloured or permed.
  • Some synthetics cannot be styled with direct heat – they will melt on contact with straighteners, tongs, blow dryer and so on. However, synthetics have come a long way in recent years and nowadays there is artificial hair that can be heat styled.
  • Acrylic hair can be set with steam and a low heat. For theatre, wigs are set as normal in rollers, then gently steamed (over a kettle or using a proper steamer) and left to dry. Depending on the quality and age of the synthetic, it can be easy to set and style, and it retains it shape and set better than real hair. This is useful for shows where there is a lot of sweaty dancing!
  • It is tough and durable, plus it doesn’t drop or lose its shape in humidity and rain like real hair does. Once washed, it will retain it’s original styling, be it curly or straight.

Horse Hair

  • Horse hair is used to make judge and barrister wigs. It gives that distinctive short and wiry white/grey hair found in these types of wig.

How a Wig is Made

Wigs are made in two main ways, namely handmade from scratch or mass produced on a production line. It is also possible to add a handmade element to a mass-produced wig. For example, you could add a made-to-measure front hair line to a machine-made wig cap.

Individually Handmade Wig

  • Normally made from hair lace and human hair, and can be made-to-measure specifically for someone.
  • Hair lace wigs used in big budget film and TV, especially on principle actors, will be handmade by a skilled wig maker specifically for the production. This helps the hair look more realistic than an off-the-shelf wig, as it is a perfect fit and the hair colour provided is according to the hair designer’s wishes. They are more expensive to buy than off-the-shelf wigs.
  • Sometimes wig makers will make generic stock to hire out to productions. These wigs will still be based on either an actual head template or typical head measurements, to ensure they are useful to as many productions as possible.

Mass Produced Wig

  • Usually made on a production line, even if there are elements of “hand tied” in the construction. Cheap hair wigs are mass produced on factory production lines, with China being a big maker of these types of wig.
  • There are some good quality wig manufacturers too. For instance, Ellen Willie, Gisela Mayer and Raquel Welch all make good quality and affordable synthetic and hair wigs for personal use.
  • Wigs can also be made from a mix of the two processes. For example, an off-the-shelf wig can be personalised with a front hairline that is made from hair lace and real hair. This would give the wearer a better fit at the front and, consequently, helps to make the wig less noticeable than a hard fronted wig. This alteration could be done by a wig maker.

  1. This is one of the best online videos I’ve ever seen. As a lace Wig-Maker myself, this is complete dreamland for me. All of those drawers with beautiful, sleek, fabulous hairs looks like complete heaven. Not to forget those rolls of lace, I only hope my skills can take me to the art of Postiche on this scale. I’d love to work for these people, wherever they are in the world. Absolutely amazing to see the whole process from start to finish.

    1. Hi Will – thank you for commenting. Hats off to all of you who make lace wigs – we appreciate the skill needed to do it. Oh yes… those drawers full of beautifully organised hair impress the hell out of us too. The video was made by these guys in the Netherlands: https://www.hetpruykenhuys.com/ 🙂

      1. It really is quite literally dreamland for me, seeing this. I didn’t realise until now, but they’re actually following me on Instagram! Of course I’ve now tapped that ‘follow back’ button to follow their fabulous work. Thanks again for letting me know where to find them!

  2. Oh. Have a look at Hallucinating Hairlines online.

    I’ve bought a wig from them and the hairline is so natural. I believe It’s half machine made and half hand tied. I didn’t have to give measurements in either.

  3. My problem with wigs is that they have too much hair. Especially for an older person, less hair looks more natural.

  4. If someone was looking at getting a wig for everyday use, would it be better to get just any old one or have one custom made? I would assume the second option since you would want it to fit well. Plus, I think it would be a good idea to choose the type of hair you want.
