BOARD (CLINICAL) EXAM QUESTIONS
AND ANSWERS
Alkaline waves - Answer-also known as cold waves; have a pH between 9.0 and 9.6,
use ammonium thioglycolate (ATG) as the reducing agent, and process at room
temperature without the addition of heat
Permanent waving - Answer-a two step process whereby the hair undergoes a physical
change caused by wrapping the hair on perm rods and then hair undergoes a chemical
change caused by the application of permanent waving solution and neutralizer
polypeptide chain - Answer-long chain of amino acids linked by peptide bonds
peptide bond - Answer-Bonds that connect amino acids.
Alkanolamines - Answer-Alkaline substances used to neutralize acids or raise the pH of
many hair products.
Used in place of ammonia because it produces less odor.
low-pH waves - Answer-Perms that use sulfates, sulfites, and bisulfites as an alternative
to ammonium thioglycolate; they have a low pH.
disulfide bonds - Answer-Strong chemical side bonds that can only be broken by
chemical solutions
Glycerine - Answer-a sweet syrupy alcohol used as a solvent & as a moisturizer in skin
& body creams
Aniline derivatives - Answer-Contain small, uncolored dyes that combine with hydrogen
peroxide to form larger, permanent dye molecules within the cortex.

-applied with bottle
-contain fewer conditioning agents and more ammonia
exothermic waves - Answer-Create an exothermic chemical reaction that heats up the
waving solution and speeds up processing
