- A.
5-10 minutes
- B.
10-20 minutes
- C.
20-30 minutes
- D.
45- 60 minutes
Correct Answer
A. 5-10 minutesExplanation
In permanent waving, most of the processing takes place within 5-10 minutes. This is because during the permanent waving process, the hair is treated with a chemical solution that breaks the disulfide bonds in the hair, allowing it to be reshaped. This chemical reaction occurs relatively quickly, and after 5-10 minutes, the hair has undergone the majority of the necessary changes. Leaving the chemical solution on for longer periods can result in over-processing and damage to the hair. Therefore, the correct answer is 5-10 minutes.Rate this question:

Correct Answer
C. Examine the scalp before the perm serviceExplanation
Before performing a permanent wave, it is important to examine the scalp. This is necessary to check for any existing scalp conditions or irritations that may affect the perm service. Examining the scalp allows the stylist to ensure that the client's scalp is healthy and suitable for the chemical process involved in the permanent wave. By doing so, any potential risks or complications can be identified and addressed before proceeding with the perm service, ensuring the safety and satisfaction of the client.Rate this question:

Which type of relaxer requires the application of a protective base cream to the entire scalp prior to the application of the relaxer?
- A.
Hydroxide relaxer
- B.
Metal hydroxide relaxer
- C.
Thio relaxer
- D.
Base relaxer
Correct Answer
D. Base relaxerExplanation
A base relaxer requires the application of a protective base cream to the entire scalp before applying the relaxer. This is done to protect the scalp from the potentially harsh chemicals in the relaxer. The base cream acts as a barrier between the relaxer and the scalp, reducing the risk of irritation or burns. This extra step is necessary to ensure the safety and well-being of the client during the relaxer process.Rate this question:
