What is the primary reducing agent in the-free waves?

Hydrogen Peroxide
Cysteamine
Ammonium Thioglycolate
Mercaptamine

The correct answer is: Mercaptamine

Mercaptamine is a natural compound found in the human body that has strong reducing properties, making it the primary reducing agent in the-free waves. Hydrogen peroxide (A) can also act as a reducing agent, but it is not the primary one in this context. Cysteamine (B) and ammonium thioglycolate (C) are both chemicals that are commonly used as reducing agents in hair perms, but they are not the primary reducing agent in this specific type of perm. It is also important to note that the terms "free waves" and "perms" are often used interchangeably, but technically refer to different types of hair treatments.
