Perm rod diameters commonly vary from which of the following ranges?

• A. 1/16 to 1 inch
• B. 1/8 to 1 1/2 inches
• C. 1/4 to 2 inches
• D. 1/2 to 1 inch

Answer: (B)

Perm rod diameters typically range from 3/16 inch to 1 inch, which is commonly utilized in the hairdressing industry. The correct choice reflects this range, encompassing rods that create varying curls depending on their size. Smaller diameters produce tighter curls, while larger diameters produce looser waves. The other options fall outside the standard diameters used in perms. For example, the first option includes diameters that are too small, while the third option includes larger diameters that are not practical for the perming process. The fourth option, although partially correct, doesn't encompass the full range commonly found in practice. Therefore, the range offered in the correct response aligns with common industry standards and practices for perm rod usage.
