Which phase of perming is the most important? Physical or chemical?

• A. Physical
• B. Chemical
• C. Both are equally important
• D. Neither is important

Answer: (C)

Both phases are essential because perming relies on shaping the hair physically and locking that shape chemically, and each step depends on the other to succeed. The physical phase is about how you wrap the hair around rods, choosing rod size, and maintaining even tension and direction. This sets the actual curl pattern, uniformity, and overall look. If this shaping isn’t done well, the final result will be uneven or misaligned, even if the chemistry is perfect.

The chemical phase handles the bond changes: the waving solution breaks disulfide bonds so the hair can take on the new shape, and the neutralizer rebuilds those bonds in the new configuration to hold it. Without proper chemical processing, the shape won’t be fixed, and the curl may not last or could revert. Without proper physical shaping, even a correct chemical change won’t yield consistent results.

So the best answer is that both phases are equally important because they work together to create and hold the perm.
