Question 1

What does 'exothermic' mean in relation to perm products?

Accepted Answer

The product generates its own heat through a chemical reaction

Answer

Exothermic perms generate their own heat through a self-activating chemical reaction when the components are mixed. This internal heat helps open the cuticle and speeds processing without an external heat source.

Question 2

What is a test curl and why is it performed?

Accepted Answer

A small section processed to evaluate curl development before processing the entire head

Answer

A test curl is performed by unwinding a perm rod slightly to check if the curl pattern has formed to the desired degree. It helps determine if processing is complete or if more time is needed.

Question 3

What wrapping technique involves wrapping hair from the ends toward the scalp?

Accepted Answer

Croquignole wrap

Answer

Croquignole wrapping starts at the ends and rolls the hair toward the scalp around the rod. It is the most common wrapping technique and produces a curl that is tighter at the ends and looser near the scalp.

Question 4

What is the purpose of end papers (end wraps) in perm wrapping?

Accepted Answer

To ensure smooth, even wrapping of the hair ends around the rod without fishhooks or crimping

Answer

End papers are placed around the hair ends to ensure they wrap smoothly and evenly around the perm rod. Without end papers, the ends can bend, buckle, or form fishhooks, resulting in an uneven curl pattern.

Question 5

What is over-processing in the context of permanent waving?

Accepted Answer

Leaving the perm solution on too long, resulting in damage, weak curls, or straight frizzy hair

Answer

Over-processing occurs when the perm solution is left on too long or is too strong for the hair type. It breaks too many disulfide bonds, weakening the hair structure and resulting in limp, frizzy, or damaged hair that may not hold a curl.
