PSI COSMETOLOGY THEORY EXAM 2023
QUESTIONS AND ANSWERS
Soft Water/ Rain water - ✔✔Best for shampooing and allows shampoo to lather freely
Hard Water - ✔✔Minerals that lessen the ability of the shampoo to lather
Purified water/Deionized water - ✔✔Main ingredient in shampoo
Surfactant - ✔✔has two ends the HYDROPHILIC HEAD and LIPOPHILIC TAIL
Hydrophilic Head - ✔✔Attracted to water
Lipophilic Tail - ✔✔Attracted to dirts and oils
Acid Balanced Shampoo - ✔✔pH of 4.5-5.5
Jheri Redding - ✔✔first to introduce pH balanced shampoo in the 1960s
Clarifying Shampoo - ✔✔acidic base to cut through buildup on the hair strand
Humectants - ✔✔Most conditioners carry this. Promote retention of moisture
Instant conditioners - ✔✔remain on the hair 1-5 minutes
Protein Conditoners - ✔✔brown liquids and penetrate into the cortex to temporarily
improve porosity and increase elasticity
Infraed Lamps - ✔✔may be used with hair treatments and scalp tonics for 5 minutes
High Frequency Unit - ✔✔used to normalize oily scalp conditioners! Also never should
be used with tonics that contain alcohol
Base Control - ✔✔position of the rod in relation to its base section
, croquignole perm wrap - ✔✔wrapped perpendicular to the scalp starting with the ends
Spiral Perm Wrap - ✔✔Wound from the ends to scalp and rods hang vertical
Concave Rods - ✔✔most common and have a smaller center circumference
Straight Rods - ✔✔uniform circumference
Alkaline Permanent - ✔✔softens and swell the hair which raises the cuticle. Developed
in 1941
Ammonium Thioglycolate (ATG) - ✔✔main ingredient or reducing agent in alkaline
perms
Alkaline Waves ( COLD WAVES) - ✔✔process at room temp
Acid Perms - ✔✔Main ingredient is glyceryl monothioglycolate (GMTG)
Exothermic perms - ✔✔reaction that causes heat. contains hydrogen peroxide
Endothermic Perms - ✔✔activated by outside heat source. True Acid perms are
endothermic
Disulfide Bonds - ✔✔if too many are broken the hair will become over processed and
have a weak curl
What is the main ingredient in a neutralizer - ✔✔Hydrogen Peroxide
Do not shampoo hair - ✔✔48 hours after a perm
Cuticle - ✔✔outer most layer of the hair
Cortex - ✔✔middle layer of the hair where all chemical processes take place
Melanin - ✔✔Natural pigment located in the cortex
