During the processing time in chemical waving, the hair will do what?

Expand
Dry out
Become straighter
Lose color

The correct answer is: Expand

Processing time in chemical waving refers to the duration during which the chemical treatment is applied to the hair, typically using a gentle waving lotion or permanent waving solution. During this time, the hair will undergo a chemical reaction which alters the structure of the protein bonds in the hair, causing it to become more malleable and take on a new shape. The correct answer is that the hair will expand during this processing time, as it absorbs and reacts to the chemicals. The other options are incorrect because B and C are not reflective of the actual chemical reaction taking place, and D is not a typical result of chemical waving. While some minimal damage to the hair may occur during the process, this is generally not significant enough to cause the hair to dry out, and the hair does not become straighter or lose color during this time.
