What should be avoided when performing a perm on hair?

Using too many rods during a perm can lead to several issues that compromise the overall quality of the perm. When performing a perm, it's essential to maintain even distribution of the curl and ensure that the hair wraps evenly around the rods. If too many rods are used, this can lead to overcrowding, which can cause uneven curls or a frizzy appearance. It may also result in hair becoming tangled or damaged due to the manipulation needed to fit the rods into place. Essentially, the right number of rods aligns with the density and texture of the hair, ensuring that the perm solution can effectively process each section evenly.

In contrast, applying conditioner before the service can affect the perm's ability to penetrate the hair properly, using a protective barrier is important for safeguarding the skin and scalp, and consulting with the client is vital to ensure their needs and expectations are met. Each of these practices serves a crucial role in maintaining hair health and achieving a successful perm.
