How to Write a Wig Spec Sheet for Your Hair Vendor

Short answer: a wig spec sheet is a one-page description of your product that a factory can follow without asking a single question. It lists the hair grade and origin, texture, length, density, lace, cap, hairline finishing, color, packaging, quantity and quality tolerances.

Our production team works from the spec sheet, not from the chat history. If a field is missing, someone on the floor fills it with the house default, and that is how a buyer who wanted 150% at the hairline gets 180% all over. A complete sheet also makes quotes comparable, gives you something to claim against if bulk goods don't match, and keeps every reorder the same as the first.

Below are the fields our production team needs for every wig, bundle and closure order, a filled-in example, and the mistakes we see most often.

The Fields Every Wig Spec Sheet Needs

  1. 1. Product and reference

    1. 01
      Your product name and SKU , so both sides talk about the same item
    2. 02
      Reference photos front, side, part and hairline. A photo of the lace and knots is more useful than a model shot.
    3. 03
      Approved sample code , if you've already approved a sample
  2. 2. Hair

    FieldWhat to writeExample
    GradeVirgin, double drawn, rawDouble drawn virgin
    OriginReal origin, not a style nameVietnamese
    TextureName plus a photoBody wave, 3 cm pattern
    LengthHow it's measured22", measured stretched from crown
    DensityPercentage, and where180% throughout, 150% at hairline

    Not sure about grades or textures? See our hair grades guide and texture chart. For typical weights by density and length, use the density and length chart.

  3. 3. Lace and cap

    FieldWhat to writeExample
    Lace materialHD, transparent, SwissHD lace
    Lace sizeExact size13x4
    Lace colorTransparent, medium brown, light brown (on request), or a swatch codeTransparent / Light Brown
    Cap sizeSize and head circumferenceMedium, 22.5"
    Cap constructionBand, combs, straps, drawstringElastic band, 4 combs, adjustable straps
    Glueless featuresIf anyPre-cut lace, wear-and-go band

    Measure your customers using our cap size guide and compare lace options in the lace types guide.

  4. 4. Hairline and finishing

    FieldOptions
    PluckingNone, light, natural (hand-plucked)
    KnotsUnbleached, bleached, bye bye knots (minimized)
    Lace cutUncut, pre-cut along hairline
    Baby hairNone, light, full, 4C kinky edges
    PartMiddle, side, free part
    StylingUnstyled, layered, curtain bangs, other
  5. 5. Color

    1. 01
      Color code for example 1B, 4, 27, 613, or your own code
    2. 02
      Color reference a hair ring code or a physical sample. Screens show colors differently, so never rely on a phone photo alone. See our color chart.
    3. 03
      Roots, ombre or highlights where they start and how wide they are
  6. 6. Packaging and labels

    • Standard packaging or private label
    • Box, bag, hair tag, cap label, care card
    • Barcode or SKU label, and where it goes
    • Artwork files and their version number
  7. 7. Quantity, delivery and quality terms

    • Quantity per item, per length and per color
    • Requested delivery date and shipping method
    • Tolerances: length, weight and shedding, for example our standards of 0.5 inch, 5 g and 10 strands
    • What happens if the goods don't match the spec

Spec Sheets for Bundles, Closures and Extensions

The same idea works for other products. The key fields change a little:

ProductMust-have fields
BundlesGrade, origin, texture, length, weight per bundle (e.g. 100 g), single or double drawn, weft type
Closures and frontalsLace size and material, lace shade, plucking, knots, part, baby hair
Tape-in extensionsTape size, pieces per pack, grams per piece, tape type, color code
WeftsWeft type (genius, hand-tied, flat), width, grams per weft, color code
Keratin tipsTip type, grams per strand, strands per pack, color code
Men's hair systemsBase type and size, base thickness, hair direction, density, color, front contour

For a fully custom order, send us your sheet through the request form on custom wigs and hair systems and we'll confirm each field with you.

Common Mistakes and What They Cost

MistakeWhat happens
Only a phone photo for colorThe shade is off because screens show color differently
No cap sizeUnits arrive in one default size that doesn't fit your customers
No density locationThe front is full and the crown is thin, or the other way round
Packaging files sent lateBulk production waits for packaging
No tolerancesYou have no agreed standard if something is wrong

Measuring method, origin names and "HD lace" without a swatch are the other common gaps; they're covered in Why Quotes for the "Same" Wig Differ.

How to Use Your Spec Sheet

  1. 1
    Send the same sheet to every vendor you're comparing, so quotes are like for like.
  2. 2
    Ask the vendor to confirm every line in writing, and to flag anything they can't do.
  3. 3
    Attach it to your order and proforma invoice.
  4. 4
    Save it with a version number Every reorder uses the same version unless you change it.

The sheet then sits at the start of the sample, inspection and claims chain described in our buying guide checklist. At our factory, every client's approved spec is saved, so reorders match the original order line by line.

FAQ

Who fills in the spec sheet, me or the factory?

Both. You fill in what only you know: your customer, lengths, color, density, packaging and quantities. The factory fills in the production details, such as weft type, knot size and lace roll, then sends the sheet back for you to sign off before the sample is made.

Do I need a spec sheet for my first order?

Yes. Even a simple one prevents most first-order problems and lets you compare quotes from different vendors fairly.

What if I don't know all the specs yet?

Fill in what you know and send reference photos. A good factory will suggest the missing details and confirm them with you before making a sample.

Can I use the same spec sheet for wigs and bundles?

You can use the same format, but bundles need weight per bundle and drawn type, while wigs need lace, cap and hairline details.

Will you keep my spec on file?

Yes. We save every approved spec and use it for all your reorders, and we never share custom specs with other clients.
