What happens to side bonds when pH balance is restored?

When pH balance is restored, side bonds, which include hydrogen bonds, salt bonds, and disulfide bonds, have the opportunity to reform. These side bonds are essential for maintaining the overall structure and integrity of the hair. When a chemical service, such as a perm or relaxer, is performed, the hair's pH can be altered, leading to the breaking of these side bonds. However, once the chemical process is neutralized and the hair returns to its normal pH level, those side bonds can reconnect, effectively reforming the structural integrity of the hair. This reformation is crucial for ensuring that the hair holds the desired shape or texture after a chemical service.
