111 Perms Flashcards
The chemical phase of perming involves all of the following EXCEPT:
wrapping hair around the perm tool
The physical phase of perming includes:
Wrapping thhe hair around a perm tool
What was the active ingredient used in the first cold wave?
Thioglycolic acid or a derivative
As added texture expands the form:
The illusion of shorter lenght is created
Partial perms are designed to:
Position added texture texture with specific areas or is desired
Positioning texture in one or more specific areas or zones of the head, or along only a certain portion of the hairstrand is called:
Texture placement
The overlap (croquignole) technique produces which result?
Undulating waves and curls
The rectangle wrap is also called the:
9-blok pattern, consists primarily of rectangular shapes throughout the pattern.
What wrapping pattern is demonstrated in the illustration?
bricklay
A neutralizer rebonds and restores the disulfide bonds in addition to which of the following?
Reduces the swelling caused by the alkalinity
Acid perms are in the pH range of:
6.9-7.2
Alkaline perms carry a pH of:
8.0-9.5
For perming, the pH of a neutralizer will range from:
2.5 to 7, depending on the type of neutralizer
Hair should be wrapped without tension when using:
Alkaline perms
Heat and wrapping with firm, even tension when using an acid perm produces which of the following effects?
Boosts penetration of glycerly monothioglycolate
In alkaline perms, the perm solution chemically breaks or reduces the:
Strong disulfide bonds
It is essential to completely rinse the perm solution before applying the:
neutralizer
Leaving the neutralizer on longer than recommended can:
Lead to hair damage
The alkalinity of cold waves causes the hair fiber to soften and:
Swell
What do low- or no-thio perms use as a reducing agent?
Cystemine hydrochloride
What is applied to a client’s hairline prior to a perm service to protect the skin?
barrier cream
What provides the tension necessary in an alkaline wave?
Swelling of the hair
What reduces the swelling of the hair and re-hardens the bonds in the new shape during a perm process?
Applying a neutralizer
When performing an alkaline wave on a client, thioglycolic acid is joined with what ingredient to shorten the processing time?
Ammonium hydroxide
Which of the following statements is true about alkaline perms?
Strong curl pattern
Which type of perm is recommended for damaged, highly porous or previously permed hair?
Acidperm
After unwinding the perm rod one and one-half times, a positive test curl resembles a(an):
S-pattern
End papers are important to control hair ends during the perming process and to:
Keep the hair smoothly wrapped around the perm tool
Hair density does not always correspond to which of the following?
Texture
Normal dry hair is capable of being stretched to what percent of its length?
0.2 (20%)
On base control is not recommended for alkaline perms since expansion is limited at the base and:
Tension may cause breakage
The following illustration indicates which tool position?
half-off base
Water left in the end papers after rinsing the perm solution will dilute the neutralizer and:
Weaken the curl formation
Which base control is the most commonly used during a perm service?
Half-off base
Overprocessed hair could be indicated by hair that may look:
Curly when wet but frizzy when dry
