What determines the size of the curl in permanent waving?
- A.
Hair color
- B.
Chemical used
- C.
Rod size
Correct Answer
C. Rod sizeExplanation
The size of the curl in permanent waving is determined by the rod size. Different rod sizes create different sizes of curls, with larger rods resulting in looser and larger curls, while smaller rods produce tighter and smaller curls. The chemical used in the permanent waving process helps to set the curl, but it does not directly determine the size of the curl. Hair color does not play a role in determining the size of the curl in permanent waving.Rate this question:

Once in the cortex, the waving solution breaks down the disulfide bonds through a chemical reaction called?
- A.
Permanent waving
- B.
Reduction
- C.
Polypeptide
Correct Answer
B. ReductionExplanation
The correct answer is "reduction." In the process of permanent waving, a waving solution is applied to the hair, which breaks down the disulfide bonds present in the cortex. This breaking down of disulfide bonds is achieved through a chemical reaction called reduction. Reduction involves the addition of electrons to a molecule, leading to a change in its chemical structure. In the context of permanent waving, reduction helps to reshape the hair by breaking and reforming the disulfide bonds, allowing for the desired wave or curl pattern to be set.Rate this question:
