PSI Cosmetology Theory Exam 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
