What is a characteristic of alkaline perms?

Alkaline perms are characterized by their strong curl pattern, which is a result of the high pH level of the alkaline perm solutions. These solutions, typically having a pH between 8.0 and 9.5, swell the hair cuticle and allow for a more significant alteration of the hair's internal structure, effectively breaking disulfide bonds more efficiently than acid perms. This reaction leads to a firmer and more resilient curl that can maintain its shape for a longer period, making it ideal for individuals seeking a more defined and lasting curl.

The strong curl pattern is often sought after by clients looking for volume and texture in their hairstyle, as these perms provide a more dramatic change compared to other perm types. The strength of the curl achieved with alkaline perms also means they can be suitable for various hair types, especially coarse, resistant hair, which may not respond as effectively to gentler perm formulations.
