Question
Permanent waves that have a 7.0 or neutral pH; because of their higher pH, they process at room temperature, do not require the added heat of a hair dryer, process more quickly, and produce firmer curls yjsn true acid waves.

|---|---|
| Permanent waves that have a 7.0 or neutral pH; because of their higher pH, they process at room temperature, do not require the added heat of a hair dryer, process more quickly, and produce firmer curls yjsn true acid waves. | Acid Balanced 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. | Alkaline Waves |
| Compounds made up of carbon, oxygen, hydrogen, nitrogen, and sulfur. | Amino Acids |
| Perms that use an ingredient that does not evaporate as readily ammonia, so there is very little odor associated with their use. | Ammonia-free Wave |
| Active ingredient or reducing agent in alkaline perms. | Ammoniun Thioglycolate (ATG) |
| Position of the tool in relation to its base section, determined by the angle at which the hair is wrapped. | Base Control |
| Also known as protective base cream; oily cream used to protect the skin and scalp during hair relaxing. | Base Cream |
| Angle at which the rod is positioned on the head (horizontially, vertically, or diagonally); also, the directional pattern in which the hair is wrapped. | Base Direction |
| Refers to the position of the rod in relation to its base section; is determined by the angle at which the hair is wrapped. | Base Placement |
| Relaxers that require the application of protective base cream to the entire sclap prior to the application of the relaxer. | Base Relaxer |
| Subsections of panels into which the hair is divided for perm wapping; one rod is normally placed on each. | Base Sections |
| Also known as straight set wrap;perm wrapping pattern in which all the rods within a panel move in the same direction and are positioned on equal-sized bases; all the base sections are horizontal, and are same length and wisith as the perm rod. | Basic Permanent Wrap |
| Perm wrap in which one end paper is folded in half over the hair ends like an envelope. | Bookend Wrap |
| Perm wrap similar to actual technique of bricklaying; base sections are offset from each other row by row, to prevent noticable splits and to blend the flow of the hair | Bricklay Permanent Wrap |
| A process or service that rearranges the structure of curly hair into a staighter or smoother form. | Chemical Hair Relaxing |
| Hair services that cause a chemical change that alters the natural wave pattern of the hair. | Chemical Texture Services |
| Perm rods that have a smaller diameter in the center that increases to a larger diameter on the ends. | Concave Rods |
| Perms in which the hair strands are wrapped from the ends to the scalp in overlapping concentric layers. | Croquignole Perm Wrap |
| Perm wrap in which partings and bases radiate throughout the panels to the follow the curvatures of the head | Curvature Permanent Wrap |
| Perm wrap in which one end paper is placed unger and another is placed over the strand of hair being wrapped | Double Flat Wrap |
| Piggyback; a wrap technique whereby extra long hair is weapped on one rod from the scalp to mis way down the hair shaft, and another rod is used to wrap the remaining strand in the same direction. | Double-rod Wrap |
| Also known as end wraps; absorbent papers used to control the ends of the hair when wrapping and winding the hair on perm rods | End papers |
| Perm activated by an outside heat source | Endothermic |
| Create an exothermic chemical reaction that heats up the waving solution and speeds up proccessing | Exothermic Waves |
| MAin active ingredient in true acid and acid-balanced waving lotions | Glyceryl Monothioglycolate (GMTG) |
| Base control in which the hair is wrapped at an angle of 90 degrees or perpendicular to its base section, and the rod is positioned half off its base section. | Half off-base Placement |
| An acid-alkali neutralization reaction (deactivates) the alkaline residues left in the hair by a hydroxide relaxer and lowers the pH of the hair and scalp; hydroxide relaxer neutralization does not involve oxidation or rebuild disulfide bonds | Hydroxide Neutralization |
| Very strong alkalis with a pH of over 13; the hydroxide ion is the active ingredient | Hydroxide Relaxers |
| Long coiled polypeptide chains. | Keratin protiens |
| Process by which hydroxide relaxers permanently straighten hair; they remove a sulfur atom from a disulfide bond and convert it into a lanthionine bond | Lanthioinzation |
| Circle rod; tool that usually about 12- inches long with a uniform diameter along the entire length of the rod | Loop Rod |
| Perms that use sulfates, sulfites, and bisulfites as an alternative to ammonium thioglycolate; they have a low pH. | Low-pH waves |
| Ionic compounds formed by a metal (sodium, potassium, or lithium) which is combined with oxygen and hydrogen, | Metal Hydroxide Relaxers |
| Relaxers that do not require application of a protective base cream. | No-base Relaxers |
| Conditioners with an acidic pH that restores the hair's natural pH after a hydroxide relaxer and prior to shampooing | Normalizing Lotions |
| Base control in which the hair is wrapped at 45 degrees below the center of the base section, so the rodis positioned completely off its base. | Off-base Placement |
| 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 | On-base Placement |
| End bonds; chemical bonds that join amino acids together, end to end in long chains to form poly peptide chains | Peptide Bonds |
| 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 perment waving soloution and neutrializer, | Permanent Waving |
| Long chains of amino acids joined together by peptide bonds | Polypeptide Chains |
| Perm wrap that only uses one end paper, placed over the top of the strand of hair being wrapped. | Single Flat Wrap |
| Tool about 12-inches long uniform in diameter along the entire length | SOft Bender Rods |
| Combination of thio relaxer and a thio permanent that is wrapped on large rods to make existing curl larger and looser. | Softer Curl Perm |
| Hair is wrapped at an angle other than perpendicular to the length of the rod, which causes the hair to spiral along the length of the rod, similar to the stripes on a candy cane. | Spiral Perm Wrap |
| Perm rods that are equal in diameter along their entire length or curling area | Straight Rods |
| Stops reaction of a perm wave solution and rebuilds the hair in its new curly form. | Thio Neutralization |
| Use the same ATG that is used in perms, but at a higher cincentration and a pH about 10 | Thio Relaxers |
| Perms that use an ingredient other than ATG as the primary reducing agent, such as cysteaminee or mercaptamine | THio-Free Waves |
| Have a pH of 4.5-7 and require heat to process; they process more slowly than alkaline waves, and do not usually produce as firm a curl as alkaline waves. | True Acid Waves |
