Study Notes
Perming Overview
- Charles Nessler created the first permanent wave machine.
- Evans and McDonough developed the first permanent wave technique without machine assistance.
- Arnold Willatt introduced cold waves, similar to modern perms, that rely on no machines or heat.
Types of Perm Products
- Perm products are classified into three categories: neutral, low/no thio, and low pH/alkaline.
Perm Solutions
- Perm Solution acts as a reducing agent to alter hair structure.
- Neutralizer serves as an oxidizing agent, essential for reforming hair bonds.
Perm Process Steps
- Hair is wrapped around chosen perm rods, and the waving lotion is applied to break disulfide bonds.
- Processing lotion softens the hair's protein structure, allowing it to mold into the shape of the rod.
- Post rinsing, a neutralizer is applied to reform the disulfide bonds in the new shape.
Alkaline Perms
- Processed without heat, alkaline perms are suitable for resistant hair types.
- pH range: 8.0-9.5; includes thioglycolic acid and ammonium hydroxide for effective processing.
- Wrapping must be done without excessive tension to avoid damage or uneven processing.
Acid Perms
- Also known as "heat perms," they are processed with the use of heat to enhance results.
- pH range: 6.9-7.2; more suitable for fragile and previously permed hair.
- Requires careful wrapping with even tension for uniform curl patterns.
Exothermic Perms
- Self-heating and self-timing through chemical reactions, exothermic perms can be either alkaline or acid.
- Suitable for various hair types with benefits similar to acid perms.
Low/No Thio Perms
- Introduced in 1992, these perms use cysteine hydrochloride as a reducing agent for clients with thioglycolic acid allergies.
- Provides deeper penetration and consistency in curls while minimizing cuticle dilation.
Ionic/Heat Perms
- Known as digital or soft wave perms, they allow for precise temperature control using computer technology.
- Produces defined curls that last 3-6 months without requiring additional styling products.
Neutralizers
- The final chemical step, neutralizers reform disulfide bonds and lower hair pH.
- Main ingredients include hydrogen peroxide, sodium perborate, or sodium bromate, each needing careful timing to prevent hair damage.
Protective Measures
- Barrier Creams protect the skin during the perm application process.
- Protective cream prevents perm solution absorption in non-processed hair areas, safeguarding against chemical exposure.
Tools and Equipment
- Cloth towels are used for blotting excess moisture and chemicals.
- Perm Bib/Neutralizing Cape catches chemicals that drip during the process.
- Picks/Stabilizers secure perm rods and prevent movement during the chemical phase.
- End Papers help control hair ends during wrapping and equalize porosity.
- Heat appliances like hood dryers and infrared lamps provide necessary heat for acid perms.
Summary of Perm Advantages
- Alkaline Perms: Strong curls, faster processing, suited for resistant hair without the use of heat.
- Acid Perms: Soft, natural curl patterns, gentler on hair, more control for fragile hair types.
