What is affected by the pH level in terms of hair strength?

Disulfide bond
Hydrogen bond
Salt bond
Peptide bond

The correct answer is: Salt bond

The pH level in terms of hair strength affects the bond formed by salt, not the other bonds such as disulfide, hydrogen, or peptide bonds. These other bonds can also contribute to the strength and integrity of hair, but they are not specifically affected by changes in the pH level. It is important to understand the different types of bonds in hair and how they are affected by different factors in order to properly care for and maintain healthy hair.
