20.1 Shaving Theory, Razor Safety, and NJ Scope

Why Domain 5 is on a cosmetology exam

Quick Answer: A New Jersey cosmetologist-hairstylist may shave or trim the beard, mustache, or other facial hair. That is not a barber-only privilege. N.J.A.C. 13:28-1.1(a)1i and N.J.S.A. 45:5B-3(j)(1) say so in almost the same words. NIC’s New Jersey Cosmetologist-Hair Stylist theory exam still weights Barbering as 5 of 110 scored items. Under N.J.A.C. 13:28-6.29, the 1,200-hour course spends 4 hours on history of barbering, 81 hours on shaving (15 class + 66 practical), and 15 hours on beard and mustache trimming (5 class + 10 practical).

Candidates skip this domain because the word barbering sounds like someone else’s license. In New Jersey it is not. The Board issues a beautician license, a barber license, and a cosmetologist-hairstylist license with different lists. N.J.A.C. 13:28-1.1(a)2 (beautician) does not list shaving. N.J.A.C. 13:28-1.1(a)3i (barber) does. N.J.A.C. 13:28-1.1(a)1i lists shaving first on the cosmetologist-hairstylist list, then hair services, color, makeup, massage of the face/neck/upper body, waxing or tweezing (not electrolysis), nails, and wigs worn on the head. You will sit the NIC New Jersey Cosmetologist-Hair Stylist theory exam, which includes Domain 5, not a national-only NIC Cosmetology form that omits barbering.

N.J.S.A. 45:5B-3(j) limits the work to the human body for cosmetic purposes and not for the treatment of disease or physical or mental ailments, offered to the general public, for male or female customers. A close shave or a beard outline is appearance work. Cutting off a mole, treating folliculitis as a medical condition, or claiming to cure a skin disease is not. If the skin is open, draining, or you reasonably believe the patron (or you) has a communicable, contagious, or infectious disease that could spread through the service, N.J.A.C. 13:28-3.3(c) and (d) tell you not to serve.

Cherry Hill example: a Friday walk-in asks whether “the stylist with the cosmetology license” can do a straight-razor shave because the barber called out. Yes, if she holds a cosmetologist-hairstylist license and the shop is authorized to offer those services. No, if she holds only a beautician or skin care specialist license. Scope follows the license on the wall, not who is free.

Curriculum hours that explain the 66 practical shaving hours

N.J.A.C. 13:28-6.29 is a time table, not a stroke diagram. Schools must deliver the hours. Know the three barbering rows because they show how much of the 1,200 hours is blade work versus beard design.

One hundred hours is not a small elective. The 66 practical shaving hours exist because a live face, a hot towel, and a blade are a blood-exposure service. History of barbering is theory only (4 and 0): licensed craft, the straight razor as a traditional tool, and New Jersey’s merger of beauty culture and barbering into one C-H license. Beard trimming is shorter because clipper-and-scissor design is a different skill from a full facial shave. Do not quote 13:28-6.29 as if it numbered 14 shaving areas. It does not.

N.J.A.C. 13:28-2.5(a)2ii requires at least one chair with an adjustable headrest suitable for shaving services in barbering shops only. Do not recite that headrest rule as a cosmetology-shop build-out requirement unless the shop is licensed as a barbering shop. A C-H shop that offers shaves still needs a safe, reclining setup and every sanitation rule in Subchapter 3; the headrest citation itself is written for barbering shops.

Straight razor, shavette, and clipper

A conventional straight razor (folding razor with a fixed steel blade) can be honed and stropped. It can give the closest shave when the edge is true and the skin is prepared. It also creates the highest blood-contact risk if angle, stretch, or sanitation slips.

A shavette (replaceable-blade straight razor) locks a disposable half-blade or full blade into a handle. You do not hone or strop a disposable blade. Insert a new blade for the patron, treat the handle as a multi-use implement that must be cleaned and disinfected, and discard the blade in a puncture-resistant sharps container. Many New Jersey shops prefer shavettes because the cutting edge is single-use.

A clipper or trimmer does not replace a shave. Clippers shorten; they do not shave the skin smooth. Use them for beard bulk, fades into the haircut, and rough outline. A T-blade trimmer details the cheek line, mustache border, and neckline. If the patron wants skin on the cheeks and a boxed beard, you still need a razor (or a foil shaver designed for skin) on the shaved zones — and you still follow razor sanitation. Do not drag a dull clipper across the face and call it a shave. That abrades the skin and still leaves stubble.

Prepare the skin before the blade moves

Consultation first. Ask about prior nicks, cold sores, dryness or thinning from prescription skin drugs (a textbook caution, not a Board drug list), keloids, and whether they want a once-over or a closer second pass. Inspect moles, raised lesions, and inflamed ingrowns. Shave around a mole; do not slice it. If you see open, draining, or clearly infected skin in the service area, decline the shave. Do not “just do the other cheek.”

N.J.A.C. 13:28-3.3(a) requires washing the hands, or using a waterless hand-washing agent, before and after each patron. Drape so clippings and lather stay off clothing. Steam or a warm towel softens the hair and raises the follicle. Apply lather (cream or soap worked to a cushion) so the blade glides. Keep lather out of eyes, nostrils, and mouth. Re-lather a zone if it dries. Linens that touch the patron must be laundered and sanitized before the next direct contact, or use disposables (N.J.A.C. 13:28-3.1(h)).

Stretch the skin taut with the free hand, usually opposite the stroke direction, so the blade meets a flat surface instead of a fold. A 30-degree blade angle is the textbook target — too steep and you dig; too flat and you skip. That angle is not an N.J.A.C. number.

Grain is the direction the hair grows out of the follicle. Rub the dry or lathered beard: the smooth way is with the grain; the rough way is against. First time over (the standard shop shave) is with the grain after lather. Second time over removes remaining stubble on damp skin, with or across the grain. A close shave against the grain is the most irritating pass and is the usual setup for ingrowns — do not treat it as the default “better” shave.

Fourteen areas and four strokes — textbook, not N.J.A.C.

Textbooks divide the face into 14 shaving areas so students do not wander. Numbering is a teaching map. It is not written into N.J.A.C. 13:28. Learn the idea: work in a set order, change stroke when the surface or grain changes, and keep the point of the razor leading.

Four positions (textbook names; some schools say freehand/backhand):

A right-handed operator usually starts on the patron’s right sideburn (area 1, freehand, down toward the jaw and mouth angle), continues across cheek and lip zones, then repeats the left side, and finishes chin, under-chin, center neck, and the area under the lower lip. Exact area-by-area numbering varies slightly by textbook; do not memorize one publisher’s map as if it were a Board rule. Wipe the blade on a clean towel as you go so lather and hair do not drag. Replace a disposable blade if it pulls; hone a conventional razor when it pulls after stropping no longer restores the edge.

Honing grinds a new bevel: pass the razor edge leading over a grit stone (coarse then fine as needed). Stropping polishes: pass back leading on leather or canvas so you do not cut the strop. Strop before a conventional-razor shave; hone when the edge is dull. Never hone a disposable shavette blade. Never strop a blade that still has hair and lather on it — clean first. These mechanics are textbook. The Board will not give you a hone-grit number in N.J.A.C.; the Board will expect the implement that touched skin to be cleaned and disinfected under N.J.A.C. 13:28-3.2(a) after every patron (N.J.A.C. 13:28-3.1(i)).

Nick protocol at the chair

A nick is a blood-contact event. Stop the stroke. Do not keep shaving “around it” with the same contaminated blade on other zones. Put on gloves if they were not already on. Apply pressure with a clean, disposable dressing. For bleeding control on a small cut, New Jersey is specific about the product: N.J.A.C. 13:28-3.4(b) says a licensee, licensed shop, or school shall not utilize styptic pencils. You may utilize styptic liquid or powder, or another single-use antiseptic product. A shared alum block or a wooden styptic pencil recapped into the kit is the classic Board-fail.

Then discard contaminated single-use items. Wash or use an approved waterless agent on your hands (N.J.A.C. 13:28-3.3(a)). Clean the razor of soil and blood with a mild alkaline detergent, rinse with tap water, and process with an EPA-registered disinfectant labeled tuberculocidal for the label contact time, or use an FDA-registered autoclave (N.J.A.C. 13:28-3.2(a)). Air-dry and store in a clean drawer. Linens that took blood go out of service until laundered per N.J.A.C. 13:28-3.1(h), or use disposables. Implements that cannot be sanitized are discarded (N.J.A.C. 13:28-3.2(d)).

Full OSHA exposure-incident paperwork, EPA registration numbers, and bloodborne-pathogen policy live in Chapter 3 (Blood Contact, OSHA, and EPA). This section only asks you to run the chair-side sequence without grabbing a banned pencil.

Newark example: you nick the thyroid area on a first time over. You freeze, grab the styptic pencil from the old barber’s drawer, tap it on the cut, wipe the razor on your towel, and keep going. Three Board problems: the pencil, the contaminated towel reused, and the blade that was not taken through 13:28-3.2 after blood. Correct sequence: stop, glove, disposable pressure, styptic liquid or powder, new blade or fully reprocessed razor, new towel, then finish only if the skin is stable and the patron consents to continue.

Jersey City example: a shavette nicks the jaw. You discard the blade in sharps, reprocess the handle, and switch to a fresh blade. You do not hone the used half-blade “to save money.”

Exam traps

• Trap: “Only barbers may shave in New Jersey.” False for C-H. Read N.J.A.C. 13:28-1.1(a)1i.
• Trap: “Styptic pencils are the professional styptic.” They are prohibited under 13:28-3.4(b).
• Trap: “First time over is against the grain because that is closest.” First time over is with the grain.
• Trap: “Honing is in N.J.A.C. 13:28-6.29 as 14 numbered strokes.” 6.29 is hours. The 14-area map is textbook.
• Trap: “A clipper sanitation spray replaces washing.” 13:28-3.2(a) starts with detergent cleaning, then rinse, then disinfectant.
