Question

Which type of bonds in the hair structure is broken down by chemical relaxers, resulting in a change in the hair's shape?

A) Hydrogen bonds
B) Ionic bonds
C) Peptide bonds
D) Disulfide bonds

Answer 1

Chemical relaxers break down the disulfide bonds in the hair structure, resulting in a change in the hair's shape.

Step-by-step explanation:

The type of bonds in the hair structure that are broken down by chemical relaxers, resulting in a change in the hair's shape, are disulfide bonds. Chemical relaxers contain alkali agents that break the disulfide bonds, allowing the hair strands to re-form in a straightened shape. Disulfide bonds are strong covalent bonds formed between sulfur atoms in the hair proteins, and they provide the structure and curl pattern in natural hair.
