Which tool is used to relax a set, backbrush, or smooth the surface of the hair?

The cushion brush is specifically designed to relax a set, backbrush, or smooth the surface of the hair due to its unique construction. This type of brush typically features a soft, cushioned base that allows for gentle manipulation of the hair. The bristles are crafted to detangle and smooth the cuticle without causing excessive damage or frizz, making it ideal for creating softer styles.

When using a cushion brush, the user can effectively work through sections of hair, allowing for comfortable and controlled styling. It is particularly beneficial for achieving volume and texture while maintaining a smooth finish. This adaptability is what makes the cushion brush the preferred choice for these particular hair techniques, setting it apart from other tools, each of which serves different purposes in hairstyling.
