Question | Answer |
The Chemical texture service that looses 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 that protects the hair from damage is the | cuticle |
The layer of hair that provides strength for elasticity is the | cortex |
hair bonds that cannot be broken by eat or water are | disulfide bonds |
the natural pH f 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 | 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, and | condition of the hair |
During the hair and scalp analysis procedure, the stylist should look for | abrasions and sign 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 is over the | double flat wrap |
Permanent wave rods are placed into 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 | 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 | thioglycolic 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 neutralizer |
An endothermic wave must be activated using an | outside heat source |
In permanent waving, the process 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 should be rinsed form the hair for a minimum of | 5 minutes |
A 90-degree perm wrap that minimizes stress and tension on the hair is | half-off based |
The process of rearranging extremely curly hair into a strighter or smoother form is | Chemical hair relaxing |
In extremely curly hair, the thinnest, weakest sections of the hair strand are located at the | twists |
Thio chemical relaxers usually have a pH value above | 10 |
The active ingredient in all hydroxide relaxers is the hydroxide | ion |
All hydroxide relaxers can swell the hair up to | twice its normal 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 never be | reformed |
Hydroxide ions left in the hair after a relaxer can be neutralized using an | 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 |
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 |
Cream used to protect the skin and scalp during a hair relaxing process is | base cream |
The strength of relaxers is determined by the concentration of | hydroxide |
To avoid over-processing during a retouch relaxer application, wait until the last fer 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 |
