Salt bonds are easily broken by:
- A.
Water
- B.
Blow-dryers
- C.
Changes in pH
- D.
High humidity
Correct Answer
C. Changes in pHExplanation
Salt bonds are formed between positively and negatively charged ions in a molecule. These bonds are relatively weak and can be easily broken when the pH of the environment changes. When the pH changes, the concentration of hydrogen ions in the solution alters, which affects the charge distribution in the molecule and weakens the salt bonds. This makes changes in pH the most likely factor to break salt bonds.Rate this question:

The single most important factor in determining the ability of hair to hold a curl it its:
- A.
Density
- B.
Elasticity
- C.
Porosity
- D.
Texture
Correct Answer
B. ElasticityExplanation
Elasticity is the ability of hair to stretch and return to its original shape without breaking. It is the most important factor in determining the ability of hair to hold a curl because hair that is more elastic will be able to stretch and conform to the shape of the curling iron or other styling tool, and then bounce back into a curled shape. Hair that lacks elasticity may not be able to hold a curl as well because it may not be able to stretch and conform to the shape of the curling iron, resulting in a looser or less defined curl.Rate this question:

Correct Answer
A. 50Explanation
A properly processed permanent wave should break and rebuild about 50 percent of the hair's disulfide bonds. This is because the process of perming involves breaking the disulfide bonds in the hair, reshaping it, and then reforming the bonds to create the desired curl or wave. Breaking and rebuilding around 50 percent of the disulfide bonds ensures that the hair retains its strength and elasticity while still achieving the desired style.Rate this question:

Too many disulfide bonds are broken
- B.
The hair is overly softened
- C.
The hair is curlier at the scalp
- D.
Too few disulfide bonds are broken
Correct Answer
D. Too few disulfide bonds are brokenExplanation
If the hair is underprocessed, it means that too few disulfide bonds are broken. Disulfide bonds are responsible for the shape and structure of the hair. When these bonds are broken, it allows the hair to be reshaped or styled. If too few bonds are broken, it means that the hair hasn't been processed enough to achieve the desired result. This can result in the hair not being as soft or as curly as intended.Rate this question:
