What is the most common neutralizer used in the permanent waving process?

1. Ammonia

2. Sodium Chloride

3. Hydrogen Peroxide

4. Sodium Hydroxide

The correct answer is: Hydrogen Peroxide

Hydrogen Peroxide is the most common neutralizer used in the permanent waving process because it works by breaking down and neutralizing the bonds of the waving solution that have been formed during the perming process. It is the most effective neutralizer because it is able to completely neutralize the chemical bonds without causing damage to the hair. The other options, ammonia, sodium chloride, and sodium hydroxide are all incorrect because they are not specifically designed to neutralize the chemical bonds formed during the perming process. Ammonia is typically used as a pH adjuster and cannot effectively break down the bonds. Sodium chloride, also known as table salt, is used in some perming solutions but only for its thickening properties. Sodium hydroxide is a strong chemical used in some relaxers but can cause significant damage to the hair if used as a neutralizer. Therefore, hydrogen
