What is a common reason for hair to become limp after a perm?

Limp hair after a perm is often a consequence of improper neutralization or excessive processing time. When hair is permed, a chemical reaction occurs that breaks and reforms the disulfide bonds in the hair structure to create curls or waves. Proper neutralization is essential to set these new bonds; if the neutralizing process is not performed correctly, the curls may lose their shape and cause the hair to appear limp and lifeless.

Over-processing can lead to the hair becoming overly soft and weak, which compromises its structural integrity and can result in a limp appearance. Neutralization also helps to close the hair cuticle and stabilize the newly formed bonds; if this step is skipped or done inaccurately, it can lead to further issues, including a loss of curl.

In contrast, the other options focus on different aspects that may influence hair texture but do not directly address the primary reasons for limpness following a perm. Using the wrong size perm rods might create curls that are not as intended but does not lead to limpness. Over-conditioning can occasionally weigh hair down but is not a common direct cause of limpness post-perm. Lastly, insufficient application of perm solution might lead to inadequate curl formation rather than limpness. Therefore, proper neutralization and avoiding
