Chemical Texture Services Flashcards

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

Answer: To stop the waving action and rebuild disulfide bonds

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

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

Answer: Coarse, low-porosity hair

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

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

Answer: Apply a protein treatment and reschedule the service

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

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

Answer: Thioglycolate, the active reducing agent

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

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

Answer: Straight set (nine-block)

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

What is the correct action if waving lotion accidentally contacts a client's eyes during a perm service?

Answer: Flush the eye with cool water for 15 minutes and seek medical attention

Chemical contact with the eyes requires immediate flushing with cool water for at least 15 minutes and referral for medical evaluation.

A sodium hydroxide relaxer has a pH of approximately:

Answer: 12.0 to 14.0

Sodium hydroxide (lye) relaxers are highly alkaline with a pH ranging from 12 to 14, the highest of any professional chemical service.
