Acid perms are generally processed with heat. Which of the following is also true about acid perms?

• A. Acid perms are the type that uses glyceryl monothioglycolate
• B. They are wrapped without tension
• C. They have high pH
• D. They do not require any processing time

Answer: (A)

Acid perms are defined by the reducing agent they use: glyceryl monothioglycolate. This chemical is what makes them acid-balanced and distinct from alkaline perms. Because GMTG is milder, acid perms typically rely on heat to activate the curl, so you still go through a processing stage to shape the hair. The other statements don’t fit: wrapping with no tension isn’t a defining trait of acid perms, acid perms aren’t high pH (they’re acid-balanced), and they do require processing time.
