chemical relaxer study guide

all of the following are reasons to study chemical texture services EXCEPT

• texture services are in high demand because they allow clients to follow popular hairstyle trends by changing the texture of their hair

• cosmetologist who understand how to perform texture services can meet client expectations while safely treating their hair

• salons require cosmetologists who perform hair color services to also preform texture services as a condition of employment

• texture services require frequent maintenance which leads to profitable and recurring appointments

how do chemical hair relaxers work

• they break down hydrogen bonds which are responsible for the hair's texture in order to change the hair from straight to curly or curly to straight

• the increase the hairs pH balance to an alkaline state which raises the cuticle layer and allows the relaxer to reach the cortex where reconstructing takes place

• they decrease the hairs pH balance to an alkaline state allowing the relaxer to reach the hair follicle which restructures the hairs texture

• they repair broken disulfide bonds that attach to the natural keratin found in hair fibers to permanently restructure the hairs shape

a higher frequency of curl reversion occurs in relaxers that use which of the following active ingredients

• ammonium thioglycolate

• ammonium sulfite

• sodium hydroxide

• guanidine hydroxide

which statement describes no-lye relaxers

• no-lye relaxers process faster than other types of relaxers because the mixture absorbs quickly and breaks the disulfide bonds faster

• cosmetologists prefer no-lye relaxers because the prevent the mineral build-up that causes hair to dry out

• no-lye relaxers increase the acidity of the hair and scalp which prevents the growth of harmful bacteria that causes brittleness

• because no-lye relaxers have a lower pH they are suitable for clients who have scalp sensitivities

hydroxide relaxers permanently straighten hair by removing one of the bonded sulfur atoms in a disulfide bond. what is the name of this process

• lanthionzation

• thio neutralization

• thermal reconditioning

• keratin smoothing

how does thio neutralization differ from hydroxide neutralization

• thio relaxers are more effective at fully straightening the hair

• the neutralization of thio relaxers involves oxidation

• cosmetologists need advanced certification to apply thio relaxers

• thio relaxers have a lower viscosity and a lower pH

a client wants to straighten coarse hair. the client mentions that their hair often seems frizzy and is concerned that if their hair loses its curl it might look even frizzier. the client also seems hesitant to make a permanent change. which service should the cosmetologist recommend

• soft curl perm

• low-pH relaxer

• jheri curl

• keratin treatment

when using relaxer products why should the cosmetologist avoid using metal clips

• then can get hot when used with a relaxer that requires heat to process

• they could cause a chemical reaction when used with a relaxer

• they break easily and tend to rust with repeated washes

• they make it more difficult to detangle the hair without pulling

which items prevents direct contact between the client and the chemical cape

• disposable gloves

• neck strips

• plastic clips

• base creams

under which of the following conditions can a texture service be preformed

• a strand analysis indicates the hair has a low porosity and high elasiticity

• a patch test shows mild redness on the scalp and the client reports slight itching

• a metallic salts test indicates the presence of metallic salts in the hair is minimal

• a scalp analysis identifies fewer than six blemishes or abrasions on the scalp
