5.7 Hairpieces, Wigs & Artificial Hair Services
Key Takeaways
- Indiana's barber curriculum allots a dedicated 50 theory hours to hairpieces — full, partial, and facial — making it one of the largest theory-only subjects in the 1,500-hour program (820 IAC 8-2-8).
- Human hair units can be cut, thermal styled, and chemically treated; synthetic units melt under heat and cannot take conventional color or perm chemistry.
- A burn test distinguishes the two: human hair burns with a sulfur odor and leaves a fine ash, while synthetic fiber melts into a hard bead with an acrid plastic smell.
- Wigs are classified as capless (wefted) or cap wigs, and are hand-tied, machine-made, or semi-hand-tied; the two core measurements are circumference and front-to-nape.
- Attachment methods run from temporary (clips, combs, adhesive tapes) to semi-permanent (bonding, weaving, fusion), and every semi-permanent method carries a documented traction alopecia risk at the anchor points.
Hairpieces, Wigs & Artificial Hair Services
Quick Summary: Indiana devotes 50 dedicated theory hours to hairpieces — full, partial, and facial — in the 820 IAC 8-2-8 curriculum, and the written examination lists artificial hair as its own sub-topic under Content Area IV.B. A barber who never sells a unit still needs to identify the fiber, avoid destroying a client's expensive human-hair piece with a hot iron, and recognize attachment damage on the scalp.
Fiber Type Decides Everything
| Property | Human hair | Synthetic fiber |
|---|---|---|
| Heat tolerance | Tolerates blow dryers and thermal irons within normal limits | Melts — most fibers deform permanently; only "heat-friendly" fibers tolerate low heat |
| Chemical services | Can be colored, toned, and permed, with caution — the hair is no longer receiving nutrients and is more porous than growing hair | Cannot take conventional oxidative color or thio perm chemistry |
| Style retention | Requires restyling after every wash | Style is heat-set into the fiber at manufacture and returns after washing |
| Appearance | Most natural movement and shine | Can look uniformly shiny; quality varies widely |
| Cost and lifespan | Higher cost, longer life with care | Lower cost, shorter life |
The burn test
Take a few strands from an inconspicuous area, hold with tweezers, and touch a flame:
- Human hair: burns with a distinct sulfur odor (from the cystine in keratin) and leaves a small amount of fine, powdery ash.
- Synthetic fiber: melts rather than burns, leaves a hard bead, and gives off a sharp, acrid plastic smell.
- Animal hair (yak, horse) behaves like human hair on the burn test but is coarser and does not blend as convincingly.
[!CAUTION] The single most expensive mistake with a client's unit is a thermal iron on synthetic fiber. It welds instantly and the damage is unrecoverable. Ask the fiber type, confirm with a burn test on a hidden strand if the client does not know, and treat any unknown unit as synthetic until proven otherwise.
Construction and Classification
Wigs
| Category | Construction | Characteristics |
|---|---|---|
| Capless (caps-less / wefted) | Rows of wefts — hair sewn to a strip — machine-sewn to strips of elastic, open between the rows | Lighter, cooler, less expensive, most common |
| Cap wig | Hair attached to a mesh, lace, or net foundation shaped to the head | More natural at the part and hairline, more expensive |
By method of attachment of the hair to the base:
- Hand-tied (hand-knotted): each strand individually knotted into the mesh; hair moves in any direction; most natural and most costly.
- Machine-made: wefts sewn by machine; durable and economical; style direction is fixed.
- Semi-hand-tied: a blend, with hand-tied hair at the part and hairline and machine wefts elsewhere.
Lace front units add a fine lace panel at the hairline so the hair appears to grow from the scalp; the lace is trimmed to shape and secured with an approved adhesive or tape.
Hairpieces
- Toupee / top piece — covers a partial area, typically the crown or top.
- Integration piece — an open-wefted base that the client's own hair is pulled through, adding density without covering the scalp.
- Facial hairpieces — mustaches, beards, and sideburns built on lace or a fine base, applied with spirit gum or a medical-grade adhesive. Indiana's 50-hour hairpiece subject expressly includes facial pieces.
Measuring
Two measurements matter for any unit, taken snugly but without compressing the hair:
- Circumference — around the head at the hairline, above the ears, and around the occipital bone.
- Front to nape — from the front hairline over the crown to the nape hairline.
Supplementary measurements include ear-to-ear across the forehead, ear-to-ear over the top, temple-to-temple around the back, and the nape width.
Attachment Methods and Their Risks
| Method | How it holds | Duration | Risk profile |
|---|---|---|---|
| Clips / combs | Mechanical clips sewn into the base | Removed daily | Lowest risk; still causes localized traction if worn in one spot daily |
| Adhesive tape / liquid adhesive | Bonded to skin or lace | Days to weeks | Contact dermatitis, folliculitis under the base; requires a patch test for adhesive sensitivity |
| Bonding | Adhesive bonds a track or unit to the hair near the scalp | Weeks | Adhesive residue, matting, breakage during removal |
| Sewn-in weave (track and sew) | Braided track on the scalp with wefts sewn to it | Weeks | Traction alopecia at the track line; scalp cannot be cleaned normally |
| Fusion | Individual strands attached with keratin or adhesive tips, sometimes with heat | Months | Heat and adhesive damage at the attachment point; breakage on removal |
The standing rule: any method that anchors added weight to growing hair transfers that weight to the follicle. Assess the client's own hair density and elasticity first, refuse a semi-permanent attachment over thin, fragile, or already-receding hairline hair, and inspect the anchor points at every visit for tenderness, pustules, and thinning.
Cutting, Blending, and Servicing a Unit
- Cut the unit on the client whenever possible. A unit cut on a block does not account for the client's head shape, growth patterns, or how it meets their own hair.
- Cut dry and cut less than you think. Fiber does not grow back, and human-hair units cannot be replaced strand by strand.
- Use shears, not thinning shears, on wefted synthetic units — texturizing can expose the weft and produce visible tracks.
- Point cutting and slide cutting soften the perimeter and are the standard for making a unit read as natural.
- Blend the client's own hair into the unit at the perimeter with clipper-over-comb or shear-over-comb, matching density rather than length alone.
- Never chemically treat a synthetic unit. For human-hair units, strand-test color and any texture service on hidden fiber first, and expect faster processing because the hair is porous.
Cleaning, disinfection, and storage
- Synthetic units: cool water, wig shampoo, no rubbing; blot and air-dry on a stand. The heat-set style returns on its own.
- Human-hair units: shampoo gently, condition, blot, and dry on a block; restyle after each cleaning.
- Between clients, anything the barber uses on a unit — combs, brushes, shears, clips — is cleaned and completely immersed in an EPA-registered disinfectant like any other implement (820 IAC 3-1-6, 820 IAC 3-1-9).
- Store units on a wig stand or block, away from direct sun and heat, so the base keeps its shape.
- A unit removed from a client is contaminated linen-equivalent until it is cleaned — never place it on a bare workstation surface, and never store a soiled unit against clean linens.
A client brings in a hairpiece and does not know whether it is human hair or synthetic. What does the burn test show if the fiber is synthetic?
Which wig construction has each hair strand individually knotted into a mesh foundation, allowing the hair to move in any direction?
What are the two core measurements taken before ordering or fitting a wig?
A client with a thinning temporal hairline requests a sewn-in weave anchored to braided tracks. What is the barber's correct assessment?
