Question | Answer |
The chemical texture service that loosens overly curly hair into a loose curls or waves is | Curl re-formation |
All chemical texture procedures involve changing the hair structure by 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 provided 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 | 4.5-5.5 |
One of the most important parts of a successful texture service is the | 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 to adjacent protein chains are joined together |
The measurement used to determine the hydrogen ions in a solution is | Potential of hydrogen |
Chemical texturizers temporarily rise the ph of the hair by lifting the cuticle layer to | Allowing 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 length texture color and | Condition of the hair |
During the hair and scalp analysis procedure the stylist should look for | Abrasion or signs of scalp diseases |
Hair texture that requires a longer processing or re wetting of solution ensure complete saturation is | Coarse textured hair |
The measurement of the number of hairs per square inch is | Density |
A indication of the strength of the side bond 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 along the entire with of the strand is a | Straight rod |
A wrapping technique using two end papers one placed under the strand and one over is the | Double flat wrap |
Permanent wave rods are placed on to subsections of a panel called | Base section |
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 is a spiral method and | Corquignole method |
A technique used to wrap extra long hair using two rods in opposite direction is a | Piggyback wrap |
A reduction reaction involves either the addition of hydrogen or removal of | oxygen |
A common colorless reducing agent used in the chemical texture service is | Thioglcolic acid |
The main reducing agent in alkaline permanents is | Ammonium thioglycolate |
Most alkaline permanent waves have a ph between | 9.0-9.6 |
The primary low ph reducing agent in acid waves is | Glyceryl monothioglycolate |
An exothermic chemical reaction produces | heat |
The basic component of acid waves are permanent wave solution and | Activator and neutralizer |
An endothermic wave must activated using | 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 should be raised 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 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 | A 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 | Guanidine hydroxide relaxer |
Lithium hydroxide relaxers and Potassium hydroxide relaxers are advertised and sold as | No lye relaxers |
Ammonium sulfite and ammonium bisulfite are marked 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 the retouch relaxer application wait until the last few minutes of the processing to apply the relaxer to the area | Closest to the scalp |
Conditioners with a acidic ph that condition and normalize hair prior to shampooing | Normalization lotion |
Curl reformation does not straighten the hair it simply makes the existing curls | Larger and looser |
To avoid scalp irritation prior to the application of the hydroxide relaxer never | shampoo the hair |

To avoid scalp irritation prior to the application of the hydroxide relaxer never | shampoo the hair |
To avoid excessive stretching of the hair when combing out tangles use a | Wide tooth comb |
Performing texture service involves powerful chemicals that must be handled with | Disregard |
The term of used to describe removing excess water before 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 the perm rods will cause band marks or | Breakage |
When working with hair that has been chemically relaxed you should avoid using | Hot irons |
