Final answer:
The result of rinsing and neutralizing a client's hair too early is weak, underdeveloped curls, as the disulfide bonds have not had enough time to set in the new shape. This process is part of applying a permanent wave and requires precise timing to ensure the curls form correctly and hold their structure.
Step-by-step explanation:
If a client's hair is rinsed and neutralized before sufficient curl formation occurs, the expected result is inadequate or incomplete curls. The process of permanent waving, or perming, involves chemically breaking down the hair's disulfide bonds and then re-establishing these bonds in a new shape around forms or curlers. If the hair is rinsed prematurely, the disulfide bonds don't have adequate time to set in the new pattern, resulting in a weaker structural formation. This could make the hair appear limp or partially straight, rather than tightly curled.
During a perm, after the hair is wrapped around the forms, a waving lotion containing chemicals that break the hair's strong disulfide bonds is applied. Once these bonds are broken, the hair can be reshaped. A neutralizer is then applied to reform the bonds in their new shape, which holds the permanent wave. When the neutralizing process is done before the hair has had enough time to process, not enough disulfide bonds are reformed, and the curl does not properly set.
