During a perm service, what determines the size and shape of the new wave or curl pattern?

Explanation:
The size and shape of the new wave or curl pattern is determined by the perm rod size. The rod acts as the form around which the hair is wrapped, and the chemical process re-forms the bonds to hold that shape. Using smaller rods produces tighter, more compact curls, while larger rods create looser waves. Processing time affects how fully the bonds are reformed and can change curl durability and visibility, but it doesn’t change the curl’s diameter set by the rod. Hair length or color don’t decide curl size; they may influence overall appearance, but the actual curl diameter comes from the rod size used during wrapping.
