Cosmetology Test Chemical Texture Services 5

Question 1

A client's hair turns into a gummy, mushy texture during a perm strand test. This indicates:

Accepted Answer

The hair is over-processed and cannot safely receive a perm

Answer

A gummy or mushy texture means the hair's protein structure has been broken down too much, making the hair too fragile for a perm service.

Question 2

What is the key difference between a 'no-base' relaxer application and a 'base' application?

Accepted Answer

No-base relaxers are applied to the hair only without pre-coating the scalp with base cream

Answer

No-base relaxers are mild enough that a protective base cream is only applied to the hairline and ears, not the entire scalp.

Question 3

Which rod size produces the tightest curl pattern in a permanent wave?

Accepted Answer

Small diameter rod

Answer

Smaller diameter rods create tighter, more defined curls because the hair wraps around a smaller circumference.

Question 4

What is 'thio-free' or 'alternative' perm chemistry based on?

Accepted Answer

Cysteamine or other non-thioglycolate reducing agents

Answer

Thio-free perms use alternative reducing agents such as cysteamine or mercaptamine that break disulfide bonds without ammonium thioglycolate.

Question 5

How long should the neutralizer typically remain on the hair during a permanent wave service?

Accepted Answer

5 to 10 minutes

Answer

Most neutralizers require 5 to 10 minutes to fully oxidize and rebuild the disulfide bonds in the new curl pattern.
