| The chemical texture service that loosens overly curly hair into loose curls or waves is | curl re-formation |
| All chemical texture procedures involve changing the hair structure using | chemical and physical changes |
| The exterior hair structure layer that protects the hair from damage is the | cuticle |
| The layer of the hair that provides strength and elasticity is the | cortex |
| Hair bonds that cannot be broken by heat or water are | disulfide bonds |
| The natural pH of hair is between | 4.5 and 5.5 |
| One of the most important parts of a successful texture service is the | client consultation |
| Permanent waves cannot be performed if the hair is coated with | metallic salts |
| Disulfide bonds are chemical-based side bonds that are formed when | sulfur atoms in two adjacent protein chains are joined together |
| The measurement used to determine the hydrogen ions in a solution is | potential of hydrogen |
| Chemical texturizers temporarily raise the pH of the hair by lifting the cuticle layer to | allow penetration to the cortex layer |
| Long, coiled polypeptide chains that are part of the hairs structure are | keratin proteins |
| The client record card should include a complete evaluation of the length, texture, color, and | condition of the hair |
| During the hair and scalp analysis procedure, the stylist should look for | abrasions or signs of scalp disease |
| Hair texture that requires a longer processing or rewetting of solution to ensure complete saturation is | coarse-textured hair |
| The measurement of the number of hairs per square inch on the head is | density |
| An indication of the strength of the side bonds is | elasticity |
| The second process of a permanent wave is the | chemical change process |
| In permanent waving, the size of the curl is determined by the | size of the rod |
| The permanent wave rod that produces a uniform curl along the entire width of the strand is a | straight rod |
| A wrapping technique using two endpapers, one placed under the strand and one over is the | double-flat wrap |
| Permanent wave rods are placed onto subsections of a panel called | base sections |
| The position of a permanent wave rod in relation to its base section is the | base placement |
| The technique of wrapping at a 90 degree angle or straight out from the center is | half-off base placement |
| The two basic types of wrapping hair around a perm rod are the spiral method and | croquignole method |
| A technique used to wrap extra-long hair using two rods in opposite directions is a(n) | piggyback wrap |
| A reduction reaction involves either the addition of hydrogen or removal of | oxygen |
| A common, colorless reducing agent used in chemical texture services is | thoglycolic acid |
| The main reducing agent in alkaline permanents is | ammonium thioglycolate |
| Most alkaline permanent waves have a pH between | 9.0 and 9.6 |
| The primary low pH reducing agent in acid waves is | glyceryl monothioglycolate |
| An exothermic chemical reaction produces | heat |
| The basic components of acid waves are permanent wave solution and | activator and neutralizer |
| An endothermic wave must be activated using a(n) | outside heat source |
| In permanent waving, the processing should be determined by the | strength of the solution |
| Hair that is too weak to hold a curl or may be completely straight after a perm is | over-processed |
| The process of stopping the action of a permanent wave is | neutralization |
| Permanent wave solution shoudl be rinsed from the hair for a minimum of | 5 minutes |
| A 90-degree perm wrap that minimizes stress and tension on the hair is | half off base |
| The process of rearranging extremely curly hair into a straighter or smoother form is | chemical hair relaxing |
| In extremely curly hair, the thinnest and weakest sections of the hair strand are located at the | twists |
| Thio chemcial relaxers usually have a pH value above | 10 |
| The active ingredient in all hydroxide relaxers is the hydroxide | neutralization |
| All hydroxide relaxers can swell the hair up to | three times its diameter |
| Hydroxide relaxers remove one atom of sulfur from a disulfide bond converting it into a | lanthionine bond |
| Disulfide bonds broken by hydroxide relaxers can nerver be | reformed |
| Hydroxide ions left in the hair after a relaxer can be neutralized using a(n) | acid-balanced shampoo |
| Relaxers containing one component used without any additional mixing are | metal hydroxide relaxers |
| Sodium hydroxide relaxers (NaOH) are commonly called | lye relaxers |
| Cream used to protect the skin and scalp during a hair-relaxing process is | base cream |
| A relaxer with two components mixed immediately prior to use is | guanidine hydroxide relaxer |
| Lithium hydroxide relaxers and potassium hydroxide relaxers are advertised and sold as | no-lye relaxers |
| Ammonium sulfite and ammonium bisulfite are marketed as | mild alternative relaxers |
| The strength of relaxers is determined by the concentrated of | hydroxide |
| To avoid overporcessing during a retouch relaxer application, wait until the last few minutes of processing to apply relaxer to the area | closest to the scalp |
| Conditioners with an acidic pH that condition and normalize hair prior to shampooing are | normalizing lotions |
| Curl reformation does not straighten the hair, it simply makes the existing curl | larger and looser |
| To avoid scalp irritation, prior to the application of a hydroxide relaxer never | shampoo the hair |
| To avoid excessive stretching of the hair when combing out tangles, use a | wide-toothed comb |
| Performing texture services involves powerful chemicals that must be handled with | caution |
| The term used to describe removing excess water before the application of a neutralizer is | blotting |
| When checking for test curl development, the test curl should reflect | firm S formation |
| When performing test curls, the rod should be unwound approximately | 1 1/2 turns |
| Incorrect placement of the rubber band of perm rods will cause band marks or | breakage |
| When working with hair that has been chemically relaxed, you should avoid using | hot irons |
