| Question | Answer |
|---|---|
| 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 than 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 as ammonia, so there is very little odor associated with their use | ammonia-free waves |
| avtive ingredient or reducing agent in alkaline permanents | ammonium thioglycolate (ATG) |
| position of the tool in realtion 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 (horizontally, vertically, or diagonally); also, the directional pattern in which the hair is wrapped | base direction |
| refers to the position of the road in realtion to its base section; base placement 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 scalp prior to the application of the relaxer | base relaxers |
| subsections of panels into which hair is divided for perm wrapping' one rod is normally placed on each base section | 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 the same length and width 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 noticeable 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 straighter 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 taht have a smaller diameter in the center that increases to a larger diameter on the ends | concave rods |
| perm wrap in which partings and bases radiate throughout the panels to follow the curvature of the head | curvature permanent wrap |
| perms in which the hair strands are warapped from the ends to the scalp in overlapping concentric layers | croquignole perm wrap |
| perm wrap in which one end paper is placed under and another is placed over the strand of hair being wrapped | double flat wrap |
| also known as piggyback wrap; a wrap technique whereby extra-long hair is wrapped on one rod from the scalp to midway down the hair shaft, and another rod is used to wrap the remaining hair 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 hair on perm rods | end papers |
| perm activiated by an outside heat source, usually a conventional hood-type hair dryer | endothermic waves |
| create an exothermic chemical reaction that heats up the waving solution and speeds up processing | exothermic waves |
| main active ingredient in true acid and acid-balanced waving lotions | glycerl 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 that neutralizes (deactivates) the alkaline residues left in the hair by a hydroxide relaxer and lowers the pH of the hair and scalp | hydroxide neutralization |
| very strong alkalis with a pH over 13; the hydroxide ion in the active ingredient in all hydroxide relaxers | hydroxide relaxers |
| long, coiled polypeptide chains | keratin proteins |
| process by which hydroxide relaxers permanently straighten hair; they remove a sulfur atom from a disulfide bond and convert it into a lanthionine bond | lanthionization |
| also known as circle rod; tool that is usually about 12 inches long with a uniform diameter along the entire length of the rod | loop rod |
| perms that use 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 restore the hair's natural pH after a hydroxide relaxers 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 rod is positioned completely off its base | off-base placement |
| Base control in which the hair is wrapped at 45-degree angle beyond perpendicular to its base section, and the rod is positioned on its base | on-base placement |
| Also known as end bonds; chemical bonds that join amino acids together, end to end in long chains, to form polypeptide chains. | peptide bonds |
| 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 | permanent waving |
| Long chains of amino acids joined together by peptide bond | polypeptide chains |
| Perm wrap that is similar to double flat wrap but used only one end paper, placed over the to of the strand of hair being wrapped | single flat wrap |
| Tool about 12-inch long with a uniform diameter along the entire length | soft bender rods |
| Combination of a thio relaxer and a thio permanent that is wrapped on large rods to make existing curl larger and looser | soft curl placement |
| Hair is wrapped at an angle other then 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 the action of a permanent wave solution and rebuilds the hair in its new curly form | thio neutralization |
| Use the same ammonium thioglycloate (ATG) that is used in permanent waving, but at a higher concentration and a higher pH (above 10 | thio relaxers |
| Perm that uses an ingredient other then ATG as the primary reducing agent, such as cysteamine or mercaptamine | thio-free 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 | true acid waves |
| The measurement of the thickness or thinness of a liquid that affects how the fluid flows | viscosity |
| Wrapping technique that uses zigzag partings to divide base areas | weave technique |
