Final answer:

Step-by-step explanation:
An acid-balanced perm is a type of chemical hair treatment used to create curls or waves in the hair. It is called 'acid-balanced' because the pH of the perm solution is adjusted to be close to the natural pH of the hair which is slightly acidic.
There are three conditions when acid-balanced perms should be used:
- When someone has fragile or damaged hair Acid-balanced perms are less harsh on the hair shaft compared to other types of perms. This makes them suitable for individuals with fragile or damaged hair.
- When someone wants loose or natural-looking curls Acid-balanced perms produce more subtle and looser curls compared to other types of perms. If someone desires a more natural look with soft waves instead of tight curls, an acid-balanced perm is a good choice.
- When someone has fine hair Acid-balanced perms are also a good option for individuals with fine hair. Because the solution is less harsh it is less likely to cause damage or weigh down the hair.
