Which reducing agent is the active ingredient in alkaline (cold) waves?
Glyceryl monothioglycolate (GMTG)
Ammonium thioglycolate (ATG)
Monoethanolamine (MEA)
Ammonium bisulfite
True acid waves require which condition to process effectively?
No heat, quick processing
Heat from an external source
Exothermic chemical reaction
Ammonia substitution
Which perm type is best suited for coarse, resistant hair?
Acid‑balanced wave
Alkaline wave
Low‑pH wave
Ammonia‑free wave
Exothermic waves differ from cold waves because they...
Require external heat
Use GMTG as the reducing agent
Generate heat internally through chemical reaction
Are odor‑free
Which wave type is marketed as “damage‑free” but can still be harmful at high concentrations?
Acid‑balanced wave
Thio‑free wave
Ammonia‑free wave
Low‑pH wave
Ammonia‑free waves substitute ammonia with which alkanolamines?
ATG and GMTG
AMP and MEA
Hydrogen peroxide and bisulfite
Cysteamine and mercaptamine
Which perm type is weakest and often marketed as a body wave?
Exothermic wave
Acid‑balanced wave
Low‑pH wave
Alkaline wave
Which statement about acid‑balanced waves is correct?
They process slowly and require heat
They process quickly without heat and produce firmer curls
They use MEA as the reducing agent
They are odor‑free
Which ingredient is shared between alkaline waves and most acid waves?
GMTG
ATG
MEA
Bisulfite
Which wave type uses ammonium sulfate, sulfite, or bisulfite as reducing agents?
Acid‑balanced wave
Low‑pH wave
Exothermic wave
Thio‑free wave
