Cosmetology Test Chemical Texture Services 2

Question 1

What is the primary purpose of a neutralizer in a permanent wave service?

Accepted Answer

To stop the waving action and rebuild disulfide bonds

Answer

The neutralizer stops the chemical waving action and uses oxidation to rebuild the disulfide bonds in the new waved position.

Question 2

Which type of hair is most resistant to chemical texture services and may require a longer processing time?

Accepted Answer

Coarse, low-porosity hair

Answer

Coarse, low-porosity hair has a tightly packed cuticle that resists chemical penetration, requiring longer processing time.

Question 3

A client's hair breaks during a strand test for a relaxer. What should the cosmetologist do?

Accepted Answer

Apply a protein treatment and reschedule the service

Answer

Hair breakage during a strand test indicates the hair is too compromised to safely receive a chemical relaxer; the service should be postponed.

Question 4

What does 'thio' refer to in the context of permanent wave chemistry?

Accepted Answer

Thioglycolate, the active reducing agent

Answer

Thio refers to ammonium thioglycolate (ATG), the reducing agent that breaks disulfide bonds in traditional alkaline perms.

Question 5

Which perm rod placement technique creates a uniform wave pattern throughout all the hair?

Accepted Answer

Straight set (nine-block)

Answer

A straight set or nine-block pattern uses consistent horizontal sections that create a uniform wave throughout the entire head.
