When using a permanent wave neutralizer, the hair is:

1. Oxidized

2. Reduced

3. Ionized

4. Dehydrated

The correct answer is: Oxidized

When using a permanent wave neutralizer, the correct answer is that the hair is oxidized. The process of creating a permanent wave involves the use of chemicals that break down the disulfide bonds in the hair. This is known as the reduction process, which is initiated with a waving solution. Once the hair is set in the desired shape, a neutralizer is applied to reform these bonds. The neutralizer contains oxidizing agents, which help to re-link the broken disulfide bonds that were altered during the waving process. The oxidation process is crucial because it stabilizes the new shape of the hair, allowing it to maintain the wave or curl. Without this step, the hair would not hold the new configuration effectively. Other options do not accurately describe the action of the neutralizer. Reduction refers to the initial part of the permanent waving process, while ionization involves changes in the electrical charge in the hair, which is not specifically related to the neutralization process. Dehydration would imply the removal of moisture, which is not the primary function of a neutralizer. Thus, understanding the role of oxidation in hair processing helps clarify the significance of the neutralizer in achieving lasting curls or waves.
