Requires only one paper, which is folded in half much like a book.
Book end wrap
A perm rod that has an even diameter/width throughout the entire rod length.
Straight Rods
pH stands for?
Potential of Hydrogen
An oily cream applied on the scalp/skin to protect from the chemicals in a relaxer.
Base Cream
Strong chemical side bonds that can only be broken by chemical solutions.
Disulfide Bonds
Processed by the application of heat. Requires outside heat source.
Endothermic Wave
Performed by stretching the hairstrand, usually before a perm service.
Elasticity Test
Formeldahyde & thioglycolic relaxer are main ingredients.
Japanese/Keratin Straightening System
Relaxer strengths.
Mild, Regular, Super
7 on the pH scale
Neutral
2 pieces of wrap paper.
Double flat wrap
Determines the required processing time and ensures that the desired curl has been achieved for a perm.
Test curl
Perm wrap that follows the curve of the head.
Curvature Perm Wrap
Solutions with an acidic pH that restore the hair's natural pH after a hydroxide relaxer.
Normalizing Lotions
Any illness caused by over-exposure to certain products or ingredients.
Occupational Disease
When a substance is not able to mix with another substance.
Immiscible
Permanent waves processed with the application of heat that have a pH range between 4.5 to 7. The main ingredient is glyceryl monothioglycolate.
True Acid Wave
A scale ranging from 0 to 14 that measures if a product is an acid (0 to 6.9), an alkaline (7.1 to 14) or neutral (7).
pH Scale
What is chemical relaxing?
Chemically straightening curly hair
Processed by chemical reaction that releases heat. Self-heating.
Exothermic Wave
Also known as End Bonds, they connect amino acids (end to end) that form polypeptides. Strong chemical side bonds.
Peptide Bonds
Also known as cold waves, processed without heat; the main ingredient is thioglycolic acid. For resistant hair.
Alkaline Wave
This perm wrap is for longer hair, the hair is wrapped on one rod from the mid-strand to scalp, and the remaining hair is wrapped around the secong rod.
Piggyback Perm
A chemical texture service that restructures overly curly hair into loose curls or waves.
Soft Curl Reformation
Physical side bond easily broken by water or heat, reforms when hair cools and/or dries.
Hydrogen Bonds
