The process of permanently rearranging the basic structure of overly curly hair into a straight form is called: | Chemical hair relaxing |
of the general types of hair relaxers , which one does not require pre-shampooing | sodium hydroxide |
the chemical required to stop the action of the chemical relaxer is the | neutralizer |
the processing time of a chemical relaxer is affected by | the hairs porosity |
what stops the action of any chemical relaxer | neutralizer |
hydroxide relaxers are usually sold in ___ formulas | base or no base |
what are the three basic steps used in chemical hair relaxing | processing, neutralizing, stabalizing |
the strength of the relaxer is determined by the strand test. General guidelines suggest that for fine, tinted, or lightened hair the following strength is used | mild |
The strength of the relaxer is determined by the strand test. General guidelines suggest that for coarse, virgin hair, the following strength us used | strong or super |
Before giving a relaxing treatment to overly curly hair, the cosmetologist must judge its texture, porosity and | elasticity, and extent of damage, if any |
the action of a sodium hydroxide relaxer causes the hair to | soften and swell |
The process of breaking the hairs disulfide bonds during processing, and converting them into lanthinonine bonds when the relaxer is rinsed from the hair is known as | lanthinization |
the scalp and skin are protected from possible burns when using a hair relaxer by applying | base creamq |
after the hair has been processed with sodium hydroxide relaxer and before the shampoo, the hair should be thoroughly | rinsed |
the relaxer cream is applied near the scalp last because processing is accelerated in this area by | body heat |
if using a "no base" relaxer, a protective base cream may be applied | to the hairline and around the ears |
the best type of shampoo to use after the chemical relaxer is | a neutralizing shampoo |
when applying sodium hydroxide relaxer, the processing cream is applied last to the | scalp area, hair ends |
when using the comb method of application, how is the relaxing cream applied | with the back of the comb |
inspecting the action of the relaxer by stretching the strands to see how fast the natural curls are being removed is called | periodic strand test |
when the hair has been sufficiently straightened, the hair is rinsed rapidly and thoroughly with__ water | warm |
the most commonly used methods of hair relaxing are the sodium hydroxide method and the ___ method | thio |
when performing a sodium hydroxide retouch, where is the product applied first | to the new growth only |
a hair relaxing treatment should be avoided when an examination shows the presence of | scalp abrasions |
to check relaxer processing, smooth and press a strand to the scalp using the back of the comb or your finger. if the curl returns, | continue processing |
the combination of a thio relaxer and a thio permanent wrapped on a large tool is called a | soft curl permanent |
what is one safety precaution that must be followed with all chemical hair relaxing services | wearing protective gloves |
one safety precaution for hair relaxing is to avoid___ the scalp with the comb or fingernails | scratching |
after saturating the rods with neutralizer in a soft curl permanent and processing according to directions, the next step is to | remove rods carefully |
relaxers which are ionic compounds formed by a metal combined with oxygen and hydrogen are known as | metal hydroxide relaxers |
sodium hydroxide relaxers are commonly called | lye relaxers |
when processing is complete for a soft curl permanent, what is done after rinsing the hair thoroughly with warm water | each curl Is towel blotted |
what is used to restore the hair and scalp to their normal acidic pH | normalizing lotion |
