Question 42

Neutralizer rehardens the chemical bonds in the hair.

The neutralizer is the perming product that rehardens the chemical bonds in the hair after the hair has been curled with a waving lotion. This step is crucial in ensuring that the new shape of the hair is locked in.

A) water

Water does not rehardens chemical bonds; rather, it is typically used in the initial stages of perming to help the hair absorb the waving lotion. While it plays a role in the process, it does not contribute to the rehardening of the hair's structure.

B) neutralizer

The neutralizer is specifically designed to rehardens the chemical bonds that were altered during the perming process. It works by stopping the chemical reaction of the waving lotion and setting the new shape of the hair, making it the correct answer.

C) conditioner

Conditioner is used to moisturize and improve the texture of the hair but does not play a role in rehardening chemical bonds. Its purpose is to provide hydration and softness rather than to assist in the perming process.

D) waving lotion

Waving lotion is the product that breaks down the hair's natural structure to allow for curling. It does not rehardens the bonds; instead, it prepares the hair for the curl. Thus, it is not the correct answer in this context.

Conclusion

The neutralizer is the essential product that rehardens the chemical bonds in the hair after perming, ensuring that the desired shape is maintained. In contrast, water, conditioner, and waving lotion serve different roles in the perming process and do not fulfill the function of rehardening the hair's structure. Therefore, option B is the definitive answer to the question.
