Which factor is essential for choosing the appropriate intensity for electrolysis treatment?

The appropriate intensity for electrolysis treatment is primarily influenced by the client's hair type. Different hair types—such as fine, medium, or coarse—respond differently to the electrical current used during electrolysis. Coarse hair generally requires higher intensity to be effectively treated, while finer hair may need a lower intensity to avoid damaging surrounding tissue. Understanding the specific characteristics of the client's hair allows the electrologist to adjust the intensity to ensure the treatment is both effective and safe, minimizing discomfort and potential adverse effects.

While skin type, length of hair, and hair color may also play roles in the overall treatment plan, it is the hair type that most directly impacts the selection of intensity during the electrolysis process.
