Electrolysis Practice Exam

What type of hair is often more challenging to treat with electrolysis methods?

1. Curly hair

2. Fine hair

3. Coarse hair

4. Vellus hair

The correct answer is: Coarse hair

The type of hair that is often more challenging to treat with electrolysis methods is vellus hair. Electrolysis is most effective on hair that has a thicker structure and is more firmly rooted, such as coarse hair. Vellus hair, which is fine, soft, and usually lighter in color, tends to be more difficult to target because of its reduced visibility and weaker roots. Coarse hair, in contrast, tends to respond better to electrolysis due to its robust follicle structure, which allows for effective treatment. While various hair types present unique challenges in electrolysis, vellus hair is particularly tricky, making it less amenable to the process.
