Low-PH Waves | Perms that use sulfates, sulfites, and bisulfites as an alternative to ammonium thioglycolate; they have a low pH |
Metal Hydroxide Relaxers | Ionic compounds formed by a metal (sodium, potassium, or lithium) which is combined with oxygen and hydrogen. |
Book End Wrap | Perm wrap in which one end paper is folded in half over the hair ends like an envelope. |
Normalizing Lotion | Conditioners with an acidic pH that restore the hair's natural pH after a hydroxide relaxer and prior to shampooing. |
Off-Base Placements | Base control in which the hair is wrapped at a 45-degree angle beyond perpendicular to its base section, and the rod is positioned on 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 perm rods, and then the hair undergoes a chemical change caused by the application of permanent waving solution and neutralizer. |
Polypetide Chains | Long chains of amino acids joined together by peptide bonds. |
Side Bonds | Bonds that cross-link the polypeptide chain together and are responsible for the extreme strength and elasticity for human hair |
Soft Bender | Tool about 12-inches long with a uniform diameter along the entire length |
Soft Curl Permanent | Combination of a thio relaxer and a thio permanent that is wrapped on large rods to make existing curl larger and looser. |
Thiogylcolic Acid | a colorless liquid with a strong, unpleasant odor, is the most common reducing agent. ammonium thioglycolate. |
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 at 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 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 techinque 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; 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 |
