Round brushes may have a core that is made out of all of the following EXCEPT

• A. Leather
• B. Metal
• C. Plastic
• D. Wood

Answer: (A)

Round brushes rely on a solid core to give the barrel its shape and to help transfer heat from styling tools into the hair. The core material needs to be rigid, durable, and able to withstand heat and moisture. Metal, plastic, and wood are common choices because they provide the necessary stiffness and stability, while also being able to be manufactured in ways that keep the brush lightweight and easy to handle. Leather, on the other hand, isn’t suitable for a brush core. It’s a flexible material that can absorb moisture, deteriorate with repeated heat exposure, and lose shape under use. Those traits would make the brush unstable and prone to damage during styling, so leather isn’t used as a core material.
