That weird, lint-like gunk clinging to your brush isn’t just hair—it’s a gross cocktail of scalp debris, product buildup, and environmental grime. Here’s what it’s made of (brace yourself) and how to keep your brush—and hair—cleaner.
What Exactly Is That Gray Fuzz?
🧴 Scalp Oil & Skin Flakes – Dead skin cells (dandruff!) + natural oils = sticky « lint. »
💇 Hair Sheds – Strands wrap around bristles, trapping other gunk.
🧼 Product Residue – Dry shampoo, hairspray, serums, and mousse build up over time.
🏡 Dust & Airborne Junk – Floating particles from your bathroom (think: towel fibers, pollen, even makeup fallout).
Result? A disgusting hairbrush biofilm that you’ve probably been re-depositing onto your hair every time you brush. (Shudder.)
