What type of brush has flexible rubberlike bristles?

The flexible rubberlike bristles are characteristic of a wet-type brush, which is specifically designed for detangling hair when it is wet. These bristles help to minimize breakage and damage to the hair, as they can glide smoothly through the strands without pulling or tugging excessively. This makes wet-type brushes particularly popular among individuals who frequently use wet styling techniques, as they effectively reduce discomfort and preserve hair health.

In contrast, natural bristle brushes are made with stiff bristles derived from animal hair, primarily used for smoothing dry hair and distributing natural oils. A collapsible brush usually refers to travel-sized or portable designs, which do not specifically feature flexible bristles. Plastic vent brushes usually have firm plastic bristles that are effective for adding volume and speed drying but do not possess the flexibility that characterizes a wet-type brush. Thus, the combination of flexibility and suitability for use on wet hair makes the wet-type brush the correct choice in this context.
