Question | Answer |
the tough exterior layer of the hair structure is called the: | cuticle |
to change the natural wave pattern of hair, the side bond of what layer of hair must be broken? | cortex |
the cortex layer of the hair structure is responsible for the hair's: | strength and elasticity |
another term that is used to described the medulla of the hair structure is the: | core |
the range of numbers used in the pH scale is: | 0 to14 |
chemical hair texturizers temporarily raise the pH of the hair in order to: | soften and swell the shaft |
in the restructuring process, coarse, resistant hair w/ a strong compact cuticle requires a chemical solution that is: | highly alkaline |
chains that are formed by peptide bonds that are linked together are: | polypeptide |
long, coiled, polypeptide chains that make up approximately 97% of the hair's structure are: | keratin proteins |
a correct permanent wave service alters only what bonds? | side |
the building blocks of proteins are: | amino acids |
chemical-based side bonds that are formed when two sulfur-type chains are joined together are: | disulfide |
weak physical side bonds that are the result of an attraction between negative and positive electrical charges are: | salt |
hydrogen bonds are easily broken by water or heat and are re-formed when the hair is: | dried |
more than any other single factor what determines the ability of the hair to hold a curl? | elasticity |
in permanent waving, the shape and type of curl are determined by the shape and type of rod and the: | wrapping method |
the wrapping technique that provides the most control over hair ends and keeps them evenly distributed over the entire length of the rods is a: | double flat |
all perm wraps begin by sectioning the hair into: | panels |
in permanent waving, panels of hair are divided into smaller subsections called: | base sections |
the angel at which a permanent wave rod is positioned on the head is referred to as: | base direction |
the two methods of wrapping the hair around a perm rod are: | croquignole and spiral |
in the croquignole method of wrapping, the hair is wound from: | ends to scalp |
once in the cortex the waving solution breaks the disulfide bonds through a chemical reaction called: | reduction |
in permanent waving, the reduction reaction is due to the addition of: | hydrogen |
the most common reducing agents used are: | thioglycolic acids |
the main active ingredient or reducing agent in alkaline permanent waves is: | ammonium thioglycolate |
most alkaline permanent waves have a pH between: | 9.0 and 9.6 |
exothermic waves create a chemical reaction that heats the solution and speeds up: | processing |
an acid w/ a low pH that is the primary reducing agent in acid waves is: | glyceryl monothiolycolate |
most acid waves have a pH value between: | 7.8 and 8.2 |
all acid waves have three components consisting of the waving lotion, neutralizer, and: | activator |
waves that are activated from and outside heat source are considered: | endothermic |
the most common reducing agents used in thio-free waves are mercaptamine or: | cysteamine |
hair that has too many disulfide bonds broken and will not hold a firm curl is considered: | over-processed |
the process of stopping the action of permanents waves and hardening the hair into its new form is: | neutralization |
two important functions performed during the neutralization process are: | deactivates solution and rebuilds disulfide bonds |
in a basic perm wrap all rods within a panel move in the same direction, and the base control is: | half off |
partings and panels that radiate through out the curved areas of the head are used in: | curvature perm wraps |
the bands of permanent wave rods should be smooth and fastened: | straight across the top of the rod |
the process of rearranging the basic structure of extremely curly hair into a straighter or smoother form i: | chemical hair relaxing |
the neutralizer used in thio relaxers is an oxidizing agent, usually: | hydrogen peroxide |
the active ingredient in all hydroxide relaxers is the: | hydrogen ion |
hydroxide relaxers remove one atom of sulfur from a disulfide bond, converting it into a(n): | lanthionine bond |
unlike thio neutralization, the neutralization process of hydroxide relaxers does not involve: | oxidation |
the application of a sodium hydroxide relaxer causes the hair to; | swell and soften |
relaxers that contain only one component and are used w/o mixing are: | metal hydroxide relaxers |
sodium hydroxide relaxers are commonly called: | lye relaxers |
relaxers that contain two components and must be mixed immediately prior to use are: | guanidine hydroxide |
relaxers are often marketed and sold as no-mix-no-lye relaxers are: | potassium hydroxide |
the difference in the strength of most chemical hair relaxers is determined by the concentration of: | hydroxide |
prior to sodium hydroxide relaxer retouch serve, the hair should never be: | shampooed |
during a retouch relaxer application, to avoid over-processing or hair breakage, do not: | overlap the relaxer |
a combination of a thio relaxer and a thio permanent wrapped on large rods is a: | soft curl perm |
hair that is treated w/ hydroxide relaxers mus not be treated w/: | thio relaxers |
