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?
It burns with a sulfur odor and leaves a fine powdery ash
It chars slowly and leaves a flexible black thread
It melts into a hard bead and gives off an acrid plastic smell
It will not ignite at all and simply discolors
Which wig construction has each hair strand individually knotted into a mesh foundation, allowing the hair to move in any direction?
Hand-tied (hand-knotted)
Machine-made wefted
Capless / caps-less
Integration piece
What are the two core measurements taken before ordering or fitting a wig?
Temple-to-temple and nape width
Circumference of the head and front hairline to nape
Ear-to-ear over the top and shoulder to crown
Occipital height and forehead width
A client with a thinning temporal hairline requests a sewn-in weave anchored to braided tracks. What is the barber's correct assessment?
Proceed, because sewn-in tracks distribute weight better than any other method
Proceed, but shampoo the scalp twice weekly to offset the added weight
Proceed only if the client signs a waiver acknowledging the risk
Decline the sewn-in method over an already-receding hairline and offer a lower-tension alternative
