Which side bond is the strongest?
The chemical/physical changes in disulfide bonds make permanent waving, curl re-forming, and chemical hair relaxing possible. Although there are far fewer disulfide bonds than salt or hydrogen bonds, they are the strongest of the three side bonds, accounting for about 1/3 of the hair’s overall strength.
Which of the side bonds is strongest Milady?
Disulfide bonds are strong, covalent side bonds that are not broken by heat or water. Although fewer disulfide bonds exist than hydrogen or salt bonds, disul- fide bonds are much stronger and account for about one-third of the hair’s over- all strength.
