Describe the difference between a temporary change and a permanent change and how the types of side bonds are affected within the hair during a service.
Be as descriptive as possible.
Temporary - salt and hydrogen bonds - physical change occurs
Permanent - salt, hydrogen and disulfide bonds - example, perming - first step would be a physical change and the second step when using the waving lotion would be a chemical change
