6.2 Braiding, extensions, wigs & hairpieces
Key Takeaways
- Cornrows are three-strand, on-the-scalp braids created with an underhand (pick-up) technique that feeds in additional hair with each pass.
- Cap wigs have an elasticized mesh base with hair often hand-knotted, while capless (caufless) wigs are machine-made wefts on elastic strips that are lighter, cooler, and most popular.
- Human hair can be thermal-styled, colored, and permed but reacts to weather and needs upkeep; synthetic fiber holds a preset style but melts under high heat.
- A match (burn) test identifies fiber: human hair burns slowly with a singed odor and leaves ash, while synthetic fiber melts, balls up, and gives off a chemical odor.
- Braids or extensions installed too tightly can cause traction alopecia, so consultation must assess scalp tension, hair density, and maintenance commitment.
Natural hairstyling and braiding
Natural hairstyling arranges the hair's own texture into braids, twists, and locks without chemically altering it. Because no chemicals are used, the service relies on clean sectioning, even tension, and the right implements: a boar-bristle brush and tail comb for parting, plus a hackle (a board of upright nails used to comb through and detangle human or extension hair) and a drawing board (two fine-toothed pads that hold loose hair while the braider draws strands from it).
Braid and twist types
- Cornrows (also called invisible braids) are narrow, three-strand braids worked flat on the scalp with an underhand (pick-up) technique, feeding in additional hair with each cross so the finished braid sits up in a visible row.
- Single braids (box braids) are free-hanging, individual three-strand braids created off the scalp; they may be done on natural hair or with added extension hair.
- Twists use two strands rather than three; flat twists lie on the scalp like cornrows, while rope and fishtail twists hang free.
- Locks (locs) are natural coils allowed to intertwine and lock permanently; they are cultivated through phases (pre-lock, sprouting, growing, and matured) and cannot be combed out once set.
A visible braid is made with the underhand (pick-up) method so the braid sits on the surface; an invisible braid uses an overhand method so it appears woven underneath. The braider draws in additional hair evenly with each cross so the row stays uniform in width and tension.
Extensions and integration
Hair extensions are additions attached to the natural hair to add length, volume, or color. A weft is a strand of hair attached to a thread; wefts may be machine-made or hand-tied. Common integration methods include:
| Method | How it attaches |
|---|---|
| Track-and-sew (sew-in) | Wefts sewn onto an on-the-scalp cornrow track |
| Bonding | Weft glued to the root area with adhesive (temporary) |
| Fusion (strand-by-strand) | Individual strands joined with keratin bonds set by a heat tool |
| Tape-in | Thin wefts pressed between taped sections |
| Link/bead (I-tip) | Strands threaded through small metal rings and clamped |
| Clip-in | Temporary wefts clipped in and removed daily |
Wigs, hairpieces, and hair fiber
Cap construction
Wigs are built on one of two base types:
- Cap wigs have an elasticized, mesh-fiber base to which the hair is attached, frequently hand-knotted (individual strands tied to the mesh). Hand-tied wigs look the most natural, let the hair move freely, and are the most expensive.
- Capless (caufless) wigs are machine-made, with rows of wefts sewn to strips of elastic. The open construction makes them lighter, cooler, less expensive, and the most popular type sold.
Human versus synthetic hair
Choosing the fiber is a core consultation decision:
| Factor | Human hair | Synthetic fiber |
|---|---|---|
| Heat and chemicals | Can be thermal-styled, permed, and colored | Melts under high heat unless heat-resistant; cannot be lightened |
| Weather | Reacts to humidity and loses its set, like natural hair | Holds a factory-preset style; unaffected by weather |
| Cost and upkeep | More expensive, needs more maintenance | Less expensive, low maintenance |
A quick match (burn) test tells the two apart: human hair burns slowly with a singed odor and leaves a small amount of ash, while synthetic fiber melts, balls up, and gives off a chemical odor or self-extinguishes.
Hairpieces
A hairpiece covers only part of the head. A men's toupee and an integration hairpiece — which has openings that let the client's own hair be pulled through and blended — are common examples, along with falls, switches, cascades, and chignons. Hairpieces attach with pressure combs, clips, or adhesive.
Consultation, hair type, and sanitation
Every braiding, extension, or wig service begins with a consultation. Assess the client's desired look, lifestyle, budget, and — critically — the maintenance commitment each option demands. Analyze hair type, density, texture, elasticity, and natural growth pattern so the added hair matches the client's own and the base or braid pattern suits the head. Matching extension texture and curl to the natural hair produces a seamless blend, and fine or low-density hair may not support the weight of long or heavy extensions. For a wig, measure the head accurately — circumference, front hairline to nape, and ear to ear — so the cap fits without slipping or excess pressure.
The most important safety point on the exam is tension: cornrows, single braids, or bonded extensions installed too tightly pull constantly on the follicles and can cause traction alopecia, a preventable form of hair loss. Braid to a comfortable tension and re-space the base at regular intervals.
Sanitation rules still apply to hair goods. Clean and disinfect all combs, brushes, clips, and metal implements between clients, and clean the hackle and drawing board the same way. Wash human-hair wigs and pieces with a gentle wig shampoo or cleaner and synthetic pieces in cool water, following the manufacturer's directions, and never share hair goods between clients without cleaning first. If a blood spill occurs during braiding, stop and follow standard blood-exposure procedures before continuing the service.
