perm wave applications work primarily by means of __________.
select the correct response:
heat, by subjecting the hair to high - temperature applications
cold and low - temperature applications to hair
light and laser applications
chemical solutions

Explanation:

Perm waves rely on chemical solutions (such as reducing agents to break disulfide bonds in hair keratin, followed by neutralizers to reform the bonds in a new curled shape). Heat, cold, or light/laser are not the primary mechanism for standard perm wave applications.

Answer:

chemical solutions
