Show answer
Reduction- What is the purpose of the neutralizer step after a perm?
Show answer
It rebuilds (re-oxidizes) the disulfide bonds in their new curved shape- Name a common oxidizing agent used in perm neutralizers.
Show answer
Hydrogen peroxide (or sodium bromate)- How does an exothermic perm generate processing heat?
Show answer
A chemical reaction within the solution itself produces heat- How does an endothermic perm generate processing heat?
Show answer
From an outside heat source, such as a hood dryer or processing machine- What is the purpose of a pre-perm test curl?
Show answer
To determine the correct processing time and expected curl result- How does higher hair porosity affect perm processing time?
Show answer
It shortens processing time because the cuticle absorbs solution faster- What is a concentric wrapping pattern used for?
Show answer
