The tool used to relax a set, backbrush or smooth the surface of the hair is referred to as a

• A. Vent brush
• B. Cushion brush
• C. Round brush
• D. Detangler brush

Answer: (B)

Understanding which brush is designed for smoothing and relaxing a hair set. The cushion brush has a soft, padded cushion under the bristles, which lets you glide through the hair with gentle, even pressure. This design is ideal for backbrushing and for smoothing the surface because it presses down slightly on the top layer without snagging or pulling, helping to relax a set and create a smooth, finished look. It distributes pressure evenly and reduces damage, making it suitable for shaping and smoothing without disturbing the overall style.

The vent brush is built to speed up drying and add lift with widely spaced bristles and vents, which isn’t aimed at smoothing or relaxing a set. The round brush is used primarily to create curl and volume during blow-drying, not to relax or smooth a finished surface. The detangler brush is designed to gently remove knots, not to relax a set or smooth the surface.
