- 1Low-pH WavesPerms that use sulfate, sulfites, and bisulfites as an alternative to ammonium thioglycolate.
- 2Metal hydroxide relaxersIonic compounds formed by a metal (sodium, potassium, or lithium) which is combined with oxygen and hydrogen.
- 3Bookend wrapPerm wrap in which one end paper is folded in half over the hair ends like an envelope.
- 4Normalizing LotionsConditioners with an acid pH that restore the hair's natural pH before the final neutralizing shampoo.
- 5Off-base placementsBase 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.
- 6Peptide bondsAlso known as end bonds; chemical bonds that join amino acids together, end-to-end in long chains , to form polypeptide chains.
- 7Permanent wavingA 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.
- 8Polypeptide chainsLong chains of amino acids joined together by peptide bonds.
- 9Side bondsDisulfide, Salt and hydrogen bonds that cross-link polypeptide chains together.
- 10Soft bender(rods)Tool about 12 inches long with a uniform diameter along the entire length.
- 11Soft curl permanentA thio based chemical service that reformats curly and wavy hair into looser and larger curls and waves.
- 12Thioglycolic acidThe most common reducing agent in permanent wave solutions.
- 13Thio neutralizationStops the action of a permanent wave solution and rebuilds the hair in its new curly form.
- 14Thio RelaxersUse the same ammonium thioglycolate (ATG) that is used in permanent waving, but a higher concentration and a higher pH (above 10)
- 15Thio-free wavesPerm that uses an ingredient other than ATG as the primary reducing agent, such as cysteamine or mercaptamine.
- 16True acid wavesHave 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.
- 17ViscosityThe measurement of the thickness or thinness of a liquid that affects how the fluid flows.
- 18Weave TechniqueWrapping technique that uses zigzag partings to divide base areas.
- 19Amino acidsCompounds made up of carbon, oxygen, hydrogen, nitrogen, and sulfur.
- 20Alkaline wavesAlso 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.
