Hair Styling & Chemical Treatments Flashcards

Which tool creates the tightest, most defined curl when used in a thermal styling service?

Answer: Marcel iron with a small barrel

A small-barrel Marcel iron creates a tighter curl because the circumference of the barrel determines the size of the wave or curl.

In hair coloring, what does the term 'double-process' mean?

Answer: Lightening hair first, then applying toner or color

Double-process color involves pre-lightening the hair and then applying a separate toner or color to achieve the desired shade.

What is the recommended water temperature for rinsing out a permanent wave solution?

Answer: Warm to comfortably warm water

Warm water thoroughly rinses the waving lotion without causing additional swelling of the hair shaft from extremes in temperature.

A client wants beachy, undone waves. Which styling method best achieves this look?

Answer: Diffused drying with a scrunching motion

Diffusing while scrunching encourages texture and a tousled wave pattern without the precision of roller sets or flat irons.

Which factor most increases the risk of hair breakage during a chemical relaxer service?

Answer: Overlapping relaxer onto previously relaxed hair

Overlapping relaxer onto previously relaxed (already straightened) hair over-processes the demarcation zone, causing extreme weakness and breakage.

What is the function of a strand test before a permanent wave service?

Answer: Assess hair's elasticity and processing time

A strand test checks the hair's elasticity and determines how quickly it processes to guide timing during the full service.

Which chemical is the active ingredient in most no-lye relaxers?

Answer: Guanidine hydroxide

No-lye relaxers use guanidine hydroxide (formed by mixing calcium hydroxide and guanidine carbonate) as the active straightening agent.
