14.2 Permanent Waving and Texturizing: Alkaline, Acid, Non-Thio, Keratin

Key Takeaways

  • NIC New Jersey Domain 2.E.1 e tests waving and texturizing as alkaline, acid, non-thio, and keratin; N.J.A.C. 13:28-6.29 clocks Permanent Waving at 25 class plus 90 practical hours (115 total).
  • Textbook waving-lotion ranges — labeled as textbook, not Board limits — place alkaline/cold ATG waves near pH 9.0–9.6 at room temperature, true acid GMTG waves near 4.5–7.0 with heat, and acid-balanced waves near 7.8–8.2.
  • Rod diameter sets curl size; croquignole wraps ends to scalp; spiral wraps along a long rod; a test curl looks for an S-shape that matches the rod before you rinse.
  • Process, rinse on the rods, then oxidize with neutralizer; leftover waving lotion keeps reducing bonds. Underprocessed hair shows a weak S and poor hold; overprocessed hair goes mushy, frizzy, and weak — overprocessing cannot be fully undone.
  • Scalp abrasions contraindicate waving; hydroxide-relaxed hair is not a thio perm candidate without a manufacturer-allowed rebuild; keratin is a CIB texturizing category with the same heated-aldehyde SDS discipline as 14.1.

Permanent waving on the New Jersey theory exam

Quick Answer: NIC New Jersey Domain 2.E.1 e tests waving and texturizing as alkaline, acid, non-thio, and keratin. N.J.A.C. 13:28-6.29 assigns Permanent Waving 25 class hours + 90 practical hours = 115 hours. Alkaline (cold) waves use ammonium thioglycolate (ATG) at a textbook pH of about 9.0–9.6 and process at room temperature. True acid waves use glyceryl monothioglycolate (GMTG) at a textbook pH of about 4.5–7.0 and need heat. Acid-balanced waves sit about 7.8–8.2 on textbook charts. Non-thio systems use reducers such as cysteamine. Keratin is a CIB texturizing category alongside those waves. Rod size, wrap, test curl, process, rinse, neutralize. Scalp abrasions contraindicate the service.

Section 14.1 took curl out with hydroxide, thio, or keratin smoothing. This section puts wave or curl in, or changes texture with a keratin texturizing system. The 115-hour NJ line is why New Jersey candidates are expected to wrap, time, and neutralize as a licensed skill, not as a weekend kit hobby. Thermal curling tools remain Chapter 12; the 45-hour thermal line does not replace this chemical clock.

New Jersey does not publish a Board pH statute for waving lotion. Every pH figure in this section is a textbook range used on NIC-style items. The bottle in your hand follows the label and SDS.

Bond logic for a thio-family perm

Hair's cortex holds keratin chains cross-linked by hydrogen, salt, and disulfide bonds. Water and wrapping rearrange hydrogen bonds so you can wind a rod; that is not why a perm survives shampooing. Waving lotion reduces disulfide (cystine) bonds so polypeptide chains can slide into the rod's shape. After a thorough rinse on the rods, neutralizer oxidizes those bonds so they rebuild as disulfide in the new configuration. Incomplete neutralization leaves bonds unstable: curl relaxes, hair stays weak, and leftover reducer can keep damaging the fiber.

Alkaline waving lotion also swells the hair and lifts the cuticle so reducer can enter the cortex. That is the same pH swelling Chapter 7 taught — applied here to rod services.

If the hair is already hydroxide-relaxed, you do not perm it. Lanthionine is not a disulfide waiting for ATG. Only a manufacturer-allowed rebuild or conversion protocol would even be discussed, and unknown history is a refuse until proven otherwise (14.1).

Four CIB waving and texturizing families

FamilyTextbook chemistry and pHProcessing cueConceptual fit
Alkaline / cold waveATG; textbook pH 9.0–9.6Room temperature; no required external heatResistant, healthy, less porous hair; firmer curl
True acid waveGMTG; textbook pH 4.5–7.0Typically requires heat (endothermic)More porous, fragile, or color-treated hair; softer curl
Acid-balanced waveOften GMTG with buffers; textbook pH 7.8–8.2May need some heatDamaged or previously colored hair when the line supports it
Non-thio waveAlternative reducer such as cysteamine hydrochloride (or other labeled non-thioglycolate reducers)Follow that product's heat and timeWhen thio chemistry is unsuitable or the client needs a different reducer
Keratin texturizingProtein/smoothing or keratin-wave systems; no Board keratin pHOften heat-sealed; SDS and ventilationCIB category for texture change that is not a classic ATG cold wave

Alkaline (cold) waves are the classic teaching perm: higher alkalinity, faster reduction, more cuticle swell, more scalp and fiber risk if you put them on already fragile hair.

Acid waves are still chemical. A low textbook pH does not make GMTG a conditioner. Repeated GMTG exposure is a known allergic sensitization risk for clients and stylists — gloves, ventilation, and history matter. True acid systems generally need heat because gentler pH does not swell the cuticle the way a pH-9.5 ATG wave does. Acid-balanced waves sit above true acid on textbook charts (about 7.8–8.2) and may process with less added heat than a true acid wave, but they are still not “pH 7 water perms.”

Non-thio waves exist so the exam (and the salon) can name a reducer that is not thioglycolate. Cysteamine is the usual teaching example. The bond story is still reduce, mold, oxidize unless that manufacturer writes a different finish. Do not invent a New Jersey non-thio pH table.

Keratin on Domain 2.E.1 e is a waving/texturizing category, not a second copy of the 14.1 hydroxide lecture. In practice it includes keratin-based waving or smoothing systems that change texture with protein plus heat rather than a classic ATG wrap. A keratin smoother is not a substitute for a properly neutralized ATG perm, and an ATG perm is not “just keratin.” Use the same formaldehyde, formalin, methylene glycol, and glyoxylic-acid SDS discipline taught in 14.1: heated products can off-gas; OSHA and FDA warnings are published federal science, not N.J.A.C. ppm. If the service is a rod perm, you still owe a test curl and an oxidizer. If the service is a keratin iron smoother, you owe ventilation and manufacturer heat passes, not an S-pattern on a gray rod.

Exothermic waves mix an activator and self-heat; endothermic waves take heat from a dryer. Those words are processing methods, usually still inside thio chemistry. They are useful teaching labels. They are not extra unpublished CIB letters.

Rod size, wrapping, and tension

The rod is the mold. Hair takes the diameter of the tool it is wound on.

  • Smaller rods → tighter curl. Larger rods → looser wave or body.
  • Section size should match the rod so hair is not overcrowded or sparse.
  • End papers control the last half-inch, protect ends, and prevent fishhooks.
  • Tension is firm and even. Yanking breaks; limp winding leaves uneven curl.

Croquignole (overlap) wrap: wind from the ends toward the scalp in overlapping layers on a rod held roughly perpendicular to the parting. Classic teaching wrap for many medium-length perms. Curl is typically tighter at the ends and looser toward the scalp.

Spiral wrap: wind along a long rod so the curl is a more uniform corkscrew from root toward end when executed correctly. Favored on longer hair when the design is elongated spiral, not a stacked croquignole set.

Base placement (on-base, half-off, off-base) changes volume at the scalp. Piggyback (double-rod) uses two rods on long hair so mid-shaft and ends both have a mold. Tool color codes (gray, pink, white) vary by manufacturer — learn small / medium / large as diameter, not as a Board-issued color chart.

Service sequence: process, rinse, neutralize

Order is a chemical safety protocol. Reversing steps is a classic exam trap and a real damage path.

  1. Consultation and hair/scalp analysis. Goals, prior color, lightener, relaxer, keratin, metallic dye. Check texture, density, porosity, elasticity, length. Scalp abrasions, inflammation, or contagious conditions contraindicate waving. Do not chemical-texture over broken skin.
  2. Strand or preliminary tests when history or elasticity is unclear.
  3. Shampoo and prep per the product. Many systems want a clarifying or gentle shampoo without a heavy conditioner that would seal the cuticle before reduction.
  4. Section and wrap with the correct rod size and pattern. Protect the hairline and eyes.
  5. Apply waving lotion so every rod is saturated. Timing starts when the manufacturer says it starts — often after full application.
  6. Process and perform a test curl. Unwind about one and a half to two turns without fully stripping the wrap. Look for a firm S-shape that mirrors rod diameter — not a limp ribbon and not a still-straight piece.
  7. Rinse thoroughly with warm water on the rods for the directed time. Incomplete rinse leaves reducer in the hair.
  8. Blot excess water so neutralizer is not overly diluted, following the product.
  9. Apply oxidizer / neutralizer for the full directed time. This rebuilds disulfide bonds. It is not optional conditioner.
  10. Unwound, final rinse, and aftercare exactly as the line diagrams (some systems finish neutralization after rods come out). Teach home care: wait period before shampoo if required, gentle products, no competing chemicals immediately.

Why rinse before neutralize: leftover waving lotion continues reducing. Oxidation cannot finish cleanly on a head still full of thio.

Underprocessed versus overprocessed

Underprocessed: weak S on the test curl; after neutralization the hair is too straight or the curl falls after the first wash. Underprocessing can sometimes be corrected later with care. It is still a failure of timing and observation.

Overprocessed: hair feels mushy, gummy, or overly soft on the rod; cuticle looks shredded; breakage; wet curl that dries into frizz with little spring. Overprocessing cannot be fully undone. You cut, condition, and wait for growth. You do not “fix it” with more lotion.

Porosity drives the window. Highly porous or previously lightened hair drinks lotion faster and overprocesses if you time it like resistant virgin hair. Low-porosity resistant hair may need alkaline strength or the product's maximum time — never past the manufacturer max. Uneven porosity (lightened ends, virgin roots) means ends finish first. Protective techniques or refusal beat a uniform clock on a non-uniform head.

A Jersey City Saturday: color-treated porous ends, resistant roots, client wants a tight spiral. If elasticity is poor on the ends, the professional answer is modify rod size and system, strand test, or no perm today — not a hotter dryer “to even it out.”

Keratin texturizing versus a rod perm, in one exam distinction

If the Prometric stem is alkaline / acid / non-thio, you are in reduce–wrap–oxidize logic. If the stem is keratin under waving/texturizing, you are in heat-sealed protein/smoothing chemistry with ventilation and SDS, not an S-pattern on a perm rod unless that keratin-wave product actually uses rods and says so. Do not collapse the four CIB words into one cream.

Contraindications

Scalp abrasions, open lesions, contagious scalp conditions, poor elasticity, metallic dyes, recent aggressive lightening, and hydroxide-relaxed hair without a manufacturer rebuild are stop signs. A signed release does not authorize waving over broken skin. Gloves, drip control, and N.J.A.C. 13:28-3.2 disinfection of rods and trays still apply: texture tools touch multiple New Jersey clients.

Exam traps

  • Trap: Acid wave means no chemical, only heat. GMTG is still a reducing agent.
  • Trap: Bigger rod equals tighter curl. Diameter and curl size move together — larger rod, looser wave.
  • Trap: Skip the rinse if the clock ran long. Rinse, then oxidize.
  • Trap: Ten minutes on the poster replaces a test curl. Porosity varies across a head.
  • Trap: Perm over a lye relaxer because “both are texture.” Lanthionization versus disulfide reduction is the 14.1 hard stop, and it still applies here.

Aftercare on the 115-hour skill

Newly waved hair is chemically swollen and then re-hardened. Treat it as a new bond arrangement, not as a wet set you can immediately bleach. Follow the line's wait before shampooing, keep mechanical tension low, and do not stack a high-lift color or a hydroxide cream in the same visit unless the manufacturer and the hair's elasticity both allow it — most exam-correct answers are wait. Document rod size, wrap pattern, lotion family (alkaline, acid, non-thio, or keratin system), processing time, and test-curl result on the client card from Chapter 8 so the next New Jersey practitioner is not guessing.
