Q: How do you clean a hair brush?
A: Lift the shed hair out with the end of a comb or a pen, then wash the head in warm soapy water, working a little shampoo through the bristles. Rinse, shake out the water and dry bristles-down so nothing sits in the cushion.
Q: What is a vent brush used for?
A: Speeding up drying. The gaps in the head let air pass straight through the brush to the hair underneath rather than being blocked by a solid pad, so a blow-dry takes less time.
Q: How do you clean a vent hair brush?
