Final answer:

Chemical waving and chemical relaxing processes involve breaking and forming bonds in the hair to change its structure.


Explanation:

In chemical waving, disulfide bonds are broken to alter the natural curl pattern of the hair. On the other hand, in chemical relaxing, bonds like disulfide bonds and hydrogen bonds are disrupted to straighten the hair.
