Cosmetology Test Chemical Texture Services Questions and Answers

Question 1

A client with fine, color-treated hair requests a permanent wave. Which type of perm solution would be the most appropriate choice to minimize potential damage?

Accepted Answer

True acid wave

Answer

True acid waves have a pH between 4.5 and 7.0 and require heat to process. They process more slowly and are ideal for extremely porous or damaged hair, such as hair that has been color-treated, because they are less damaging than alkaline waves.

Question 2

During a chemical relaxer service, the primary role of the neutralizer is to:

Accepted Answer

Harden and reform the disulfide bonds in their new, straighter alignment.

Answer

After the relaxer has broken the disulfide bonds to straighten the hair, the neutralizer is applied to rebuild these bonds in their new shape. This process is what permanently locks the hair into its new, straighter form.

Question 3

A stylist is performing a virgin sodium hydroxide relaxer application. Where should the relaxer cream be applied first?

Accepted Answer

The mid-shaft, staying 1/2 inch away from the scalp.

Answer

The scalp generates heat, which can cause the relaxer to process faster near the roots. Therefore, in a virgin application, the relaxer should be applied to the mid-shaft first, then the ends, and finally to the scalp area to ensure even processing.

Question 4

Which of the following chemical texture services rearranges overly curly hair into a looser curl or wave pattern, rather than straightening it completely?

Accepted Answer

Soft curl permanent

Answer

A soft curl permanent is a thio-based chemical service that restructures overly curly hair into a larger, looser curl pattern. It is essentially a combination of a relaxer and a permanent wave.

Question 5

Before applying any chemical texture service, a stylist must perform a strand test. What is the primary purpose of this test?

Accepted Answer

To check for the presence of metallic salts and determine processing time.

Answer

A strand test is crucial for safety and to ensure a successful outcome. It reveals how the hair will react to the chemical, indicates the presence of metallic salts which could cause severe damage, and helps the stylist accurately determine the required processing time for the desired result.
