What can result from improperly neutralizing hair after a perm?

Improperly neutralizing hair after a perm can indeed lead to non-uniform curls. Neutralization is a crucial step in the perming process, as it helps to reform the bonds in the hair after they have been altered by the perm solution. If this step is neglected or not done correctly, the hair may not set into the designed curl pattern effectively.

As a result, you might find that some sections of the hair have stronger curls while others may remain limp or straight, leading to a lack of consistency across the entire head of hair. This unevenness is primarily due to the hair bonds not being adequately reformed in all areas, which can affect the final appearance of the curls.

In contrast, other outcomes like permanent straightening or excessive frizz typically stem from different aspects of the perming process, such as the application of the perm solution itself or not following the correct processing times, rather than directly from the neutralization step. Therefore, the focus on neutralization is essential for achieving the desired uniformity in curls.
