Free Milady Chemical Texture Services Questions and Answers — Questions and Answers
Question 1: The two principal actions in permanent waving are:
- Wrapping and drying
- Physical and chemical (Correct answer)
- Sectioning and applying
- Rinsing and neutralizing
Correct answer: Physical and chemical
Permanent waving involves a physical change, which is the wrapping of the hair on perm rods, and a chemical change, caused by the waving lotion and neutralizer. Both actions are required to restructure the hair's disulfide bonds.
Question 2: What type of curl is produced by a concave perm rod?
- A uniform curl from scalp to ends
- A tighter curl at the ends and a looser curl near the scalp (Correct answer)
- A looser curl at the ends and a tighter curl near the scalp
- A loose, body wave only
Correct answer: A tighter curl at the ends and a looser curl near the scalp
Concave rods are smaller in diameter in the center and larger on the ends. This design causes the hair wrapped around the smaller center to form a tighter curl, resulting in a curl that is tighter at the ends and looser near the scalp.
Question 3: The main active ingredient in an alkaline permanent wave is:
- Ammonium thioglycolate (Correct answer)
- Sodium hydroxide
- Hydrogen peroxide
- Glyceryl monothioglycolate
Correct answer: Ammonium thioglycolate
Ammonium thioglycolate (ATG) is the reducing agent used in alkaline perms, which are also known as cold waves. It works at a higher pH to swell the cuticle and break the disulfide bonds in the hair's cortex.
Question 4: What is the primary function of the neutralizer in a permanent wave service?
- To break disulfide bonds
- To soften the hair's cuticle
- To rebuild and reharden disulfide bonds (Correct answer)
- To remove the waving lotion from the hair
Correct answer: To rebuild and reharden disulfide bonds
The neutralizer, typically containing hydrogen peroxide, performs two functions: it deactivates any remaining waving lotion and rebuilds the disulfide bonds into their new curled shape. This process locks the curl into place.
Question 5: Hair with high porosity generally requires which type of chemical service solution?
- A more alkaline solution and longer processing time
- A less alkaline solution and shorter processing time (Correct answer)
- A stronger neutralizer to ensure curl formation
- Pre-softening with a higher pH solution before the service
Correct answer: A less alkaline solution and shorter processing time
Highly porous hair has a raised cuticle layer that absorbs chemicals quickly and can be easily damaged. It requires a less alkaline solution (lower pH) and a shorter processing time to prevent over-processing and breakage.
Question 6: Before applying a sodium hydroxide relaxer, a cosmetologist must NOT perform which of the following steps?
- Analyze the client's hair and scalp
- Perform a strand test
- Shampoo the hair (Correct answer)
- Section the hair into four quadrants
Correct answer: Shampoo the hair
Shampooing the hair before a sodium hydroxide relaxer can irritate the scalp and remove its natural protective oils (sebum). This increases the risk of scalp burns and irritation from the highly alkaline chemical relaxer.
