"Licensed cosmetologist uncovers the truth behind hairbrush 'dust bunnies' - time to clean yours!"

Licensed cosmetologist Casey Davis revealed on TikTok that the "dust bunnies" found in hairbrushes are actually a combination of dead skin cells and oil buildup. She recommended a cleaning regime involving hot water, clarifying shampoo, baking soda, and an old toothbrush to dissolve the buildup. Davis advised washing hairbrushes every few weeks or monthly, but more frequently if there is significant buildup. It is also important to replace hairbrushes regularly if the bristles are worn off or broken.
