7.3 Braiding, Locking, Hair Extensions, and Hair Enhancement Systems
Key Takeaways
- M.G.L. c. 112, § 87V expressly exempts natural hair braiding from the Board's rules and regulations, so braiding alone requires no Massachusetts licence - but a barber who cuts, chemically treats or shaves in the same service is practising barbering and is fully regulated.
- Traction alopecia is the defining risk of every added-hair service: excessive tension at the follicle causes a receding, thinning perimeter that becomes permanent once follicles scar.
- Locks develop through recognized phases - pre-lock, sprouting, growing, maturing and rooted - and the pre-lock coil must not be disturbed by shampooing or manipulation before it begins to bud.
- Attachment methods trade speed against risk: adhesive bonding and heat fusion add chemical and thermal hazard, sewn tracks and micro-links add tension, and every method requires a planned removal.
- Hair replacement bases are lace, monofilament or polyurethane, and every adhesive or solvent used with them requires a predisposition test, good ventilation and intact scalp skin.
Braiding, Locking, Hair Extensions, and Hair Enhancement Systems
Exam Alert: Hairstyling is 5% of the test - about 4 scored items - but PSI enumerates this material in unusual detail: procedures for textured hairstyling broken into hair extension application, maintenance and removal, locking and braiding, followed by procedures for hair additions, replacements and enhancements with hair piece application, maintenance and removal. Four scored items across that much ground means the questions will be about safety, tension and removal, not about artistry.
The Massachusetts Braiding Exemption
Massachusetts draws a line here that many states do not, and it is worth knowing precisely.
M.G.L. c. 112, § 87V ends with: "Natural hair braiding shall be exempt from the rules and regulations issued by the board." A person who only braids natural hair - no cutting, no chemicals, no shaving - is outside the Board's regulatory reach and needs no barber or cosmetology licence in the Commonwealth.
That exemption is narrow, and a licensed barber cannot shelter under it:
- Braiding plus a haircut, an outline, a shave, a colour service or a chemical texture service is barbering as defined in M.G.L. c. 112, § 87T, and every rule in 240 CMR 8.00 applies to the whole service.
- The shop is still a licensed barber shop, so 240 CMR 8.02 governs the premises, the sanitation, the linens and the implements regardless of which service is being performed.
- Every comb, clip, hook and pair of shears used in a braiding service is an implement that contacts a patron, so 240 CMR 8.02(7)(a) still requires cleaning and disinfection before each patron.
Tension: The Risk That Runs Through Everything
Every service in this section adds weight and tension at the follicle, and every one of them can cause traction alopecia - progressive hair loss along the hairline, temples and part lines caused by sustained mechanical pull. It begins as thinning and a receding perimeter with short broken "fringe" hairs; if traction continues long enough the follicle scars and the loss becomes permanent.
Warning signs to check at every appointment and to teach the client:
- Tenderness, headache or a "tight" sensation after installation - pain is never normal
- Small pustules or bumps at the base of braids or at link sites in the days after installation
- Redness or shine along the hairline
- Short broken hairs at the perimeter, or a hairline that has moved back since the last visit
The rule: if the client reports pain, or if the scalp is visibly lifted or dimpled around the base, the installation is too tight and must be released - not endured until it "settles."
Additional protective standards: keep the perimeter and nape looser than the interior, avoid installing over an already-thinned hairline, give the scalp rest periods between installations, and never install on hair that is chemically compromised from a recent relaxer, perm or heavy lightening.
Braiding
| Style | Structure | Notes |
|---|---|---|
| Two-strand twist | Two sections wound around each other | Lowest tension; a common starter for locking |
| Three-strand (visible) braid | Braided over, sitting on top of the scalp | Free-hanging; tension is set at the base only |
| Cornrow (inverted / underhand braid) | Braided under, so the braid sits against the scalp and follows a parted row | Tension is applied along the entire row; the highest-risk pattern for traction |
| Box braids | Free-hanging braids from square-parted sections, often with added hair | Weight of added hair magnifies tension at the base |
| Fishtail / rope | Decorative variations | Same tension principles apply |
Sectioning matters as much as technique. Clean, even partings distribute weight; ragged or over-large sections concentrate it. Added hair should be no heavier than the natural section can carry, and should be attached a short distance from the scalp rather than tied directly at the follicle.
Locking
A lock (loc) is hair permanently matted and intertwined into a single unit. Locking is a progression, not a single service, and the phases are commonly examined:
| Phase | What is happening | Service implication |
|---|---|---|
| Pre-lock / starter | Coils are formed but the hair remains soft and the coil pattern is still visible and intact | Do not disturb. Frequent shampooing, combing or heavy manipulation unravels the coil |
| Sprouting / budding | The coil begins to swell and bulge; hair inside starts to interlace and the pattern blurs | Gentle maintenance only; the lock is fragile |
| Growing / teen | The lock is closed but irregular, may shrink and behave unpredictably | Retwist the new growth at the base at planned intervals; resist over-tightening |
| Maturing / adult | The lock has firmed and holds its shape; length becomes visible again | Regular base maintenance; watch for thinning at the root |
| Rooted | The lock is dense, closed and stable along its full length | Maintenance is mostly base retwisting and cleansing |
Methods: comb technique (a fine comb rotated to coil the section), palm rolling (the section rolled between the palms), and interlocking (the tail of the lock drawn back through the base with a tool). Interlocking holds longer and is popular for fine hair, but repeated interlocking at the same point creates a weak spot in the shaft.
Maintenance cautions: over-frequent retwisting and retwisting that is too tight are the leading causes of thinning locs and traction loss at the root. Heavy waxes and petrolatum-based "locking gels" trap dirt inside the lock, do not rinse out, and cause build-up and odour. Locks must be dried thoroughly - a lock that stays damp internally can develop mildew and an irreversible smell.
Hair Extensions
| Method | How it attaches | Principal hazards | Removal |
|---|---|---|---|
| Sew-in / track (weave) | Wefts stitched to a cornrowed track with a curved needle | Tension along the whole track; tight tracks cause traction alopecia and follicular pustules | Cut the thread only, never the client's hair; unbraid the track |
| Bonding / adhesive | Weft glued to the base of the natural hair with adhesive | Adhesive allergy; adhesive on the scalp; matting on removal | Dedicated bond remover, dwell time, gentle release - never pulled |
| Fusion / keratin bond | Keratin tips melted to small sections with a heat tool | Thermal burn to the scalp; heat damage to the shaft; weight per bond | Solvent softens the bond, then a bond breaker; never force |
| Tape-in | Adhesive-tape wefts sandwiching a thin section | Slippage on oily hair; adhesive residue | Solvent-based tape remover |
| Micro-link / bead / cylinder | Section drawn through a small metal or silicone-lined ring, then crimped | Point tension at one spot; ring too tight cuts the shaft; sliding causes matting | Open the ring with the correct pliers, never crush or cut |
| Integration / hair addition system | A mesh base with hair attached, blended into the client's own hair drawn through | Weight; tension at attachment points | Release attachment points; clean the base |
Non-negotiables regardless of method:
- Consult and assess first. Fine, chemically overprocessed or already-thinning hair cannot carry weight. Check density and tensile strength at the sections that would bear the load.
- Never install over an active scalp condition. 240 CMR 8.02(9) forbids treating any skin disease, and an occlusive installation over an inflamed scalp makes it worse.
- Predisposition-test adhesives and solvents. They are potent sensitizers; the 24-to-48-hour test used for aniline colour applies in principle here too.
- Ventilate. Bond removers and adhesive solvents are volatile organic compounds - see Section 2.3.
- Plan the removal at the moment of installation. Book the take-down date. Extensions left in far past their intended life mat at the base, and the resulting removal costs the client far more hair than the service ever added.
- Removal is chemical and patient, never mechanical and fast. Every documented case of extension-related hair loss on removal comes from pulling.
Hair Replacement Systems and Hairpieces
| Base material | Character | Best for |
|---|---|---|
| Lace (French or Swiss) | Fine, breathable mesh; hair hand-tied knot by knot; most natural front hairline | Front hairlines and full-lace units; fragile, shorter service life |
| Monofilament | Fine mesh with a slightly denser weave; hair moves multi-directionally | Crown and part areas; balance of realism and durability |
| Polyurethane ("skin") | Thin polymer film; hair injected or knotted and sealed | Tape and adhesive attachment; most durable, least breathable |
| Hybrid | Lace front with a poly perimeter | Natural front plus a secure adhesive edge |
Attachment: double-sided tape (easiest to reverse, needs regular re-taping), liquid adhesive (longest hold, highest sensitizer risk), clips or combs (no adhesive, but concentrated tension at each clip), and weaving or integration into the client's own hair.
Application, maintenance and removal:
- Prepare the scalp: clean, dry, free of oil and residue, and intact. Never apply adhesive over abraded, sunburned or inflamed skin.
- Template and cut-in: the unit is fitted, then the hair is cut in and blended to the client's own hair - this is where a barber's shear and clipper work carries the service.
- Maintain on a schedule: re-tape or re-bond at the manufacturer's interval; cleanse both the unit and the scalp beneath it. Skin under a poly base is occluded and needs deliberate cleansing.
- Remove with the matched solvent, allowing full dwell time, easing rather than peeling from the perimeter inward. Peeling a bonded poly base off dry takes the client's own hairline with it.
- Store the unit on a block, cleaned and dry, never damp and never crushed.
