Final answer:
If a new perm is not neutralized properly, it can lead to adverse effects on the hair such as dryness, breakage, and brittleness.
Step-by-step explanation:
If a new perm is not neutralized properly, it can lead to adverse effects on the hair. During a perm, chemicals are applied to the hair to change its structure and create curls or waves. The neutralizing step is crucial to stop the chemical reaction and lock in the new shape of the hair.
If the perm is not neutralized properly, the chemicals may continue to react with the hair, causing excessive damage. This can result in dryness, breakage, and brittleness of the hair. It is important to ensure the proper neutralization of the perm to maintain the health and integrity of the hair.
