A perm is designed to chemically alter the structure of the hair to create waves or curls. This process involves the use of chemical solutions that break and reshape the hair's natural bonds. When the hair is wrapped around rods and treated with these chemicals, it takes on a new shape, resulting in the desired wavy or curly pattern.

This transformation occurs because the perming process helps to establish long-lasting curls or waves that can significantly enhance the texture and volume of the hair. The technique can vary in size and tightness of the curls, but regardless of the specific method, the end result is curled or wavy hair, making this the correct answer.

In contrast, straight hair and straightened hair would not be the result of a perming process, as these options indicate a lack of wave or curl. Frizz, while it might occur due to humidity or damage to the hair, is not a deliberate result of perming but rather an undesired side effect in many cases. Therefore, the type of wave pattern created by a perm is specifically curls or waves.
