Summarize the following:
It's important to immediately remove any excess water that has collected in the bristles or on the pad of a wooden brush. Moisture can cling and seep into brush bristles, cloth brush pads, and wood causing mold and rot. Using a cloth, gently press between the bristles to reach the surface of the cylinder or pad. Make sure to use adequate pressure to soak up any excess moisture. Once you have absorbed excess moisture, it's important to allow the brush to fully dry before use. Place the bristles facing down on a clean and dry towel and allow to dry overnight. If you need to use your brush right away, use a hair dryer set to its lowest setting to speed the drying process. Go back and forth over the brush a few times to blow out any remaining water drops and to ensure that the hairbrush is now damp rather than soaking wet.

Summary:
Use a clean dry cloth to dry your hairbrush if you have a wooden handle or paddle. Lay your hairbrush, bristles facing down, on a cloth to air dry. Use a hair dryer to quickly dry your hairbrush.
