| Question | Answer |
| Low-pH Waves | Perms that use sulfate, sulfites, and bisulfites as an alternative to ammonium thioglycolate. |
| Metal hydroxide relaxers | Ionic compounds formed by a metal (sodium, potassium, or lithium) which is combined with oxygen and hydrogen. |
| Bookend wrap | Perm wrap in which one end paper is folded in half over the hair ends like an envelope. |
| Normalizing Lotions | Conditioners with an acid pH that restore the hair's natural pH before the final neutralizing shampoo. |
| Off-base placements | Base control in which the hair is wrapped at 45 degrees below the center of the base section , so the rod is positioned completely off its base. |
| Peptide bonds | Also known as end bonds; chemical bonds that join amino acids together, end-to-end in long chains , to form polypeptide chains. |
| Permanent waving | A two step process whereby the hair undergoes a physical change caused by wrapping the hair on perms rods; the hair then undergoes a chemical change caused by the application of permanent waving solution and neutralizer. |
| Polypeptide chains | Long chains of amino acids joined together by peptide bonds. |
| Side bonds | Disulfide, Salt and hydrogen bonds that cross-link polypeptide chains together. |
| Soft bender(rods) | Tool about 12 inches long with a uniform diameter along the entire length. |
| Soft curl permanent | A thio based chemical service that reformats curly and wavy hair into looser and larger curls and waves. |
| Thioglycolic acid | The most common reducing agent in permanent wave solutions. |
| Thio neutralization | Stops the action of a permanent wave solution and rebuilds the hair in its new curly form. |
| Thio Relaxers | Use the same ammonium thioglycolate (ATG) that is used in permanent waving, but a higher concentration and a higher pH (above 10) |
| Thio-free waves | Perm that uses an ingredient other than ATG as the primary reducing agent, such as cysteamine or mercaptamine. |
| True acid waves | Have a pH between 4.5 and 7.0 and require heat to process; they process more slowly than alkaline waves , and they do not usually produce as firm a curl as alkaline waves. |
| Viscosity | The measurement of the thickness or thinness of a liquid that affects how the fluid flows. |
| Weave Technique | Wrapping technique that uses zigzag partings to divide base areas. |
| Amino acids | Compounds made up of carbon, oxygen, hydrogen, nitrogen, and sulfur. |
| Alkaline waves | Also known as cold waves; they have a pH between 9.0 and 9.6 use ammonium thioglycolate (ATG) as the reducing agent, and process at room temperature without the addition of heat. |
