What term describes the angle at which a permanent wave rod is positioned on the head?

• A. Base direction
• B. Base angle
• C. Rod angle
• D. Anchor direction

Answer: (A)

Base direction is the term that describes the angle at which the perm rod sits on the head. This orientation determines the curl direction and the overall pattern you’ll see after processing. By choosing the base direction, you control how the curl forms relative to the scalp and how strong or loose it will be, especially when considering base placement like on-base or off-base. Other terms refer to different aspects of placement, but base direction specifically captures the directional orientation of the rod itself.
