Measure the length and width of the bald area on your head to be covered. Length is from where you want your hairline, to the back where your growing hair remains. Width is above the ears, across the top, from the borders of your real hair.

Method One:

If the stock hairpiece is longer or wider, or both, use hairpiece tapes to mark out a smaller footprint to match your measurements. Make it a bit bigger because you can always repeat to make it smaller. At the front, place the tape behind any empty lace or excess membrane that you want to trim away and then measure from there. The advantage to this method is your tapes will always be perfectly aligned along the edge. Use a sharp razor blade to go along the guideline formed by the outside edge of your tapes.

Method Two:

If you have a template, attach the stock unit over the top with tape, aligning the front edge, Then use a razor blade or scalpel to reduce the size around the sides and back, from underneath. Not using scissors means you cannot accidentally cut the edge hairs short. Or measure the length and width and attach tapes to the bottom to make a cutting edge guide.

If you happen to still have a universal shipping mold, while it is not your own head curvature, you can trim one to make an excellent resizing template, that is more rigid than a tape template.

To resize you will need:

  • A tape measure, or…
    • Your template or a trimmed universal shipping mold.
  • Hairpiece tape.
  • Scalpel or razor blade.


Information about the base, or foundation of your hairpiece or wig. This is the fabric or membrane to which the hairs are attached.

Various Materials described:
  • Lace is a polyester woven fabric.
  • Polyskin or Poly is a polyurethane membrane formed out of liquid plastic to various thicknesses.
  • Monofilament is a nylon mesh, either welded or woven. These are legacy materials, and no longer recommended for hairpieces. French lace is a better material.
  • Actually most base choices are back on the menu but we need to discuss each and every order before getting started, so please get in touch.

  • Remove the hairpiece before washing it, and then use cool or cold water
  • Use good mild shampoo and very good after-shampoo conditioner
  • Release the lace from the adhesive thoroughly with isopropyl alcohol so you don’t pull knots out
  • Wash lace with water flow from bottom to top to prevent wash through of hairs
  • In case of highly chlorinated or very hard tap water, use bottled or filtered water
  • Avoid using a hair dryer or any hot tools
  • Do not force out tangles. Comb the ends first and then go a bit lower with each stroke


When an older unit has developed rough texture it can be revived a few times with warm water deep conditioning, and with refreshing hair trims, in which the worn ends of all hairs are cut shorter.


Seems simple, but it is not. Please read the following information about curl and wave.

  • Natural Indian hair is slightly wavy, but you can have very straight hair or very curly hair and anything in between.
  • The tighter perms do certainly adversely affect the silky quality of the hair. It is unavoidable due to chemistry.

The wavelength below is shown in centimeters. 1.0 cm is sometimes shown as 10 mm.

Wavelength or curl size is a literal measurement of a wet curl. if you have hair with some length and wet a section, you can measure your natural wavelength. If not just remember 1 cm really is 1 cm.

Wavelengths of 2.5 cm and longer are achieved with a water-based perm and wavelengths or 2.2 cm and shorter are achieved with a chemical perm. Chemically permed hairpieces should never be brushed or combed. Condition deeply and lift with a pick if necessary, but brushing permed hair will make it frizzy hair.

The hairpiece factory does not perm hair. These days it already comes in set wavelengths from the supplier. This means that we offer curl right down to the base. For looped membrane type bases, very curly hair is not offered as the technique becomes impossibly difficult.

Here is the list of standard perm-rod sizes. The descriptive names beside each (eg. light curl, very wavy) are not standardized and for visualization only:

The following wavelengths are provided as chemically permed hair. This hair should never be brushed or combed out or it will be permanently frizzy. You cannot order these wavelengths on membrane type bases.

  • Tight Afro 0.2cm (custom tool) Do not brush out
  • Afro 0.4cm (yellow rod) Do not brush out
  • Loose Afro 0.5 to 0.6cm (red rod) Do not brush out
  • Tightest Curl 0.8cm (blue rod) Do not brush out
  • Tight Curl 1.0cm (pink rod) Do not brush out
  • Very Curly 1.2cm to 1.3cm (gray rod) Do not brush out
  • Curly 1.5cm (white rod) Do not brush out
  • Loose Curl 1.8cm (lavender rod) Do not brush out
  • Light Curl 2.2cm (purple rod) Do not brush out

The following wavelengths are provided as “water-permed” hair.

  • Very Wavy 2.5cm (orange rod) Water perm
  • Wavy 3.0cm (green rod) Water perm
  • Light Wave 3.2cm (custom tool) Water perm
  • Body Wave 3.8cm (custom tool) Water perm
  • Straight 5cm (Natural Indian hair averages 5cm wave without treatment)
  • Chinese hair and synthetic hair can be ordered with zero curl.
  • It is human hair, so you can style out the curl to some extent, or reactivate it with water or a styling product. Once again, it’s human hair so it behaves like the hair that grows, or used to grow, from your head. Like any perm, it may relax over time if brushed too much or blow dried.
  • Donor hair is fairly straight. The permanent wave process may not be entirely permanent. Even synthetic hair, which is curled with dry steam, will relax to a straighter form over time at approximately the same rate as human hair. The same care procedures will prolong this curl also.
  • If the curl is, for example 1.0cm (one centimeter), then it means that if the hair is long enough to form a circle when it is wet, the circle will have a 1 centimeter diameter. The curl choices represent the diameter of a wet curl.


  • CoolPiece hairpieces do not come with a final hairstyle. You are advised to see your stylist to make the best of your new hair.
  • The length you ask for is approximate. Very short hair cannot be handled by the technicians who make the units for you.
  • Plan on getting a haircut when you receive your order.
  • There are no fixed directions on lace. You can redirect with a brush. After a certain haircut, you may find it best to keep that style, but the new unit can be changed.
  • Injected polyskin has a fixed unchangeable direction.

Freestyle is generally forward but can be styled many ways including back. The crown is not defined but it is somewhere near the center line, and there are no gaps or partings. Freestyle is the most popular choice and can be used as a starting point for most hairstyles

Pompadour Freestyle as seen here on Sean Connery and James Dean, is similar to Freestyle in that there is no defined crown and the hair on top comes forward, but then at the front it elevates. With long hair length this creates a Rockabilly look, and with short hair it gives a neat top with a fashionable spiked up hairline. There are many variations possible with a Pompadour Freestyle unit.

Spiky usually means all the hair stands up and is directed away from the scalp. It can look punky or it can look militaristic depending on the amount of texturizing product applied, and on the length of the hair. With curly hair, it can give an elevated riot of curls. In actual fact, the factory treats spiky orders in much the same way as freestyle orders, because the spiky effect is not part of the manufacturing process, but rather part of the wearer’s haircut and styling.

Center crown, left crown and right crown have a defined crown. All the hair is directed away from one point, either in the center of the crown or to one side, and therefore you will always see bare scalp at the crown point. We usually boost the density a bit at the crown point so it does not look too bald in that spot, but if you don’t like that spot to be there, get freestyle instead.

If you order back, or comb back or brush back or flat back, all the hair will be back and there will be no crown.

Left part, right part and center part feature an open parting along which you can see the base or the scalp through the base, depending on if it’s lace or a skin base. The parting really has to stay in the same place where the factory puts it and it should not be moved to either side afterward, because special knotting and density considerations are designed into the hairpiece.

The generic style illustrations above are for descriptive purposes only and do not depict actual hairpieces. The style/direction you order is your starting point for the final hairstyle that you and your stylist create. Hairpieces come uncut and unstyled and always need to be cut-in.

HOW TO MAKE A TEMPLATE (mold). The key to custom ordering.

For small units under 7 inches long, then length*width is usually good enough. Larger sizes will fit better if a template is used. Note of the length times the width exceeds 500 square centimeters, you are in the large category.

Items required:
  • Clear Plastic Food Wrap, for example, Saran Wrap or Glad Wrap
  • Clear heavy-duty packaging tape or reinforced strapping tape. (Important as this will not shrink over time)
  • A permanent marker and a washable marker or grease pencil
  • Scissors
  • Hand mirror and wall mirror.
Making the Template

Establish how much of your remaining hair has insufficient surviving density and needs to be covered by the hairpiece. This may not be an obvious line, but aim for where the density just looks too low at the sides and back.

Draw your new hairline on your skin from temple to temple using a grease pencil or washable felt marker. If you will be using tape at the front of your new piece, use the same shape tape as a stencil for this line. Don’t be a wolf man, the center front of your hairline is at least four fingers above the bridge of the nose.

  • Dampen your hair to help it lay flat against your head. (If necessary)
  • Pull a large section of wide clear plastic food wrap such as Saran Wrap over your head from ear to ear, so that it covers the balding area and beyond. (You can tape two narrower strips together if that’s all you have.)
  • Use the permanent marker to draw your hairline and the border between your hair and your balding area onto the plastic. This line will be the perimeter of the hairpiece
  • This is the most important stage: After the lines are drawn to your satisfaction, you should reinforce the template with wide clear glossy packing tape so it is thick, rigid and strong and locked into the exact shape of the top of your head.
  • The template should cover the bald area right to the edge with no gap but should not overlap the real hair on your head.
  • Remove it from your head and cool off.
  • If necessary go over the perimeter line with the marker again and mark the front with a letter F.
  • Cut away the excess so that all that remains is the mold of your area to be covered. Anything over that line, we don’t need. Cut it off.
  • Place it back onto your head and check all around using a wall mirror and a hand mirror.
  • If the template does not extend to the growing hair edge at the back, no need to start over, just extend the edges with heavy duty parcel tape and trim it to a size larger than the first cut.
  • Please use the permanent marker to write your name and a date on the template.
  • If you are measuring for a full wig it is the same method, although more difficult.

Temple pairs:

The factory charges one price for any size up to 500 square centimeters, based on length times width. This is one reason why we ask for a template to be made a certain way for temple pairs. The other reason is that a small triangular template can be in any of three directions, or six if it’s flipped. Therefore the way to do this is to make a bridge template, and we can cut off the bridge later.

Using a cosmetic pencil or washable marker on your skin, draw in your area of coverage at each temple and connect them with a thin stripe (the bridge) a few millimeters wide. Make the template to that shape and cut it out, and mark the front edge with an F. Mark your left with an L and your right with an R and write the word top on the hair side.

Sending it in:

This type of tape-template can be folded flat and sent in a flat envelope.


There are so many different ways to do any of this, but here are some useful tips for beginners or people not doing well with their usual methods.


  • Remove frequently for comfort, hygiene and scalp health.
  • Tie a bandana (not a banana) around your head to protect your eyes from the alcohol in the lace release or the ingredients of the solvents that you use.
  • If its a lace unit, drip or squirt lace release or alcohol through the lace from a very close distance to the head, then wait for it to work and then lift off the unit
  • If it’s a non-porous base, such as polyskin, raise an edge and spray alcohol under the unit, progressively peeling back the base until it’s off.
  • When removing tapes from polyurethane, be very careful not to tear thinner membrane such as 2-3 MIL types. Don’t put tape on membranes thinner than 4 MIL.


  • To clean glue residue from lace, push the underside firmly across a mirror, a hard countertop or some cling film attached to either. This pulls the glue away from the lace and onto that surface.
  • To remove tapes from lace or monofilament, apply alcohol from the hair side and then peel away
  • If there is stubborn residue, use a safe solvent (citrus type) to dissolve, then follow up by removing that solvent with alcohol, then shampoo to neutralize.


  • You are strongly advised to experiment to find your best options for various base types over time.
  • CoolPiece does not currently feature a tape, glue and accessories store.


Available types of hair

Indian Human (default)Our long staple of Indian supply will hopefully remain reliable, and we continue to source this from long standing partners. Our source remains as ethical as it always was, which is individual hairs harvested from voluntary hair brushing by people inside India, later chemically processed into top grade product for wig making. No pony tails cut off, no religious tonsuring, no prisoner hair, no cadaver hair, no drain hair, no involuntary harvesting from donors under questionable circumstances. We see evidence that it is still the same Indian hair.
SyntheticOur synthetic “hair “is Kanekalon® type K7 Modacrylic Fiber, which is a permanently self-extinguishing, melt-resistant “hair” with a limiting oxygen index of 28, and is a modern variety of a basic product invented in Japan in 1957. Wave and curl can be set or reset in hot water rather than with chemical perms. We cannot bleach the knots so when brown or black it is not ideal for lace bases (which have exposed knotting). Synthetic gray can brightly reflect UV “black light”. When used with care it will outlast human hair. It is always available and is unaffected by the politics or regulation of human hair supply.
Legacy typesWe can not currently guarantee the authenticity or ethical source of the following hair types:Remy Indian, European Remy, Virgin hair, Chinese straight, Yaki Texture, Mongolian, Russian, Indonesian, Brazilian. We are therefore not making them available.

Colors and pricing

As of 2020, some lighter hair colors carry a surcharge. The custom order form will add $30 for colors #22R, #30R, #60RYH, #613. Human gray costs +$30 also. This is due to shortages that became apparent in 2020 and may change when we resume mass production of custom units.

Black hair and lace

If you want jet black color #1, please note that knot bleaching is ineffective on color #1. We advise that you choose a membrane base rather than lace if you want #1 black, or go with color #1B if you insist upon lace.

60RYH white hair

When you receive this human gray hair, it might look yellow. This is just a starting point and it is not ready to use yet. Shampooing with a blond (purple) shampoo will make it white, then you may need to apply a toner to get your desired shade of gray, (or bright fashion color if you prefer). If you are confident you will not be in UV black light (eg halloween/nightclub), synthetic gray is easier to manage.

Knot bleaching (lace hairpieces)

At the factory we bleach knots enough to help hide them, but not so much that the hair sheds too fast. It’s a narrow target range and we usually hit the sweet spot.

  • It should not be necessary to try to bleach the knots any further, however, if you want to further bleach your knots yourself, (human hair only), it’s at your own risk. But it is very easy.
  • Besides the suggestion photo below, there are several YouTube videos online that demonstrate this process or something similar.
Knot bleaching

White or blond knots and post-production dyed hair

We decline to provide this service. The factory will not do it and there are several reasons. Results usually disappoint. Just a millimeter or two shy of base level and the first length of hair above the base retains the transparency of the blond or white color and this ruins the look of short haircuts. Conversely, if we go a tiny bit too far, the knots gets dyed dark and the base gets stained and ruined. Then there is a large financial loss, a long delay during a fresh start remake, and we destroyed a beautiful new piece.

However, our factory knot bleaching is great, even for #1B darkest natural brown. #1 jet black does not respond to bleach so we suggest you do not pair black hair with lace bases.


  • Always wash out swimming pool water a.s.a.p.
  • Knot bleaching is a way to minimize the dotty appearance that can be seen when dark hair is tied to lace.
  • We do not accept any type of hair sent from the client for use in manufacturing of CoolPiece hairpieces. But the hair that we use is very well regarded by our clients.
  • Donor hair does not come from religious ceremonies. It is harvested from hair brushing, no hair is cut off the donors.
  • Don’t specify knotting method, we use the least visible possible in all situations.


Spot highlights are areas of a lighter color hair interspersed with the darker color hair. They can look like stripes because the hair is all one color from knot to tip. They are named for the spotty color that results underneath the lace. These highlights have alarmed some clients so we discourage ordering factory highlights.

Even highlights are just a color change. e.g. color #2 with 50% even highlights in color #4 will look the same as color #3. You can potentially get a wrong color by guessing these. It is better to provide a good color sample for custom matching.

Real highlights are done afterwards by your stylist/colorist. They can be expensive but this is how to get correct expert highlighting and they will not have to go all the way down to the knot, so no stripes.
