If a person shaves their head, can they still get dandruff?
-- Slap-head, UTC
Technically, yes. That's using the broadest definition of "dandruff," of course -- flakes of dead skin breaking free of your scalp. Dead skin bits are continually flying off our bodies. Most of the time they're too small to notice. But when minuscule expired scalp flakes get oily and clump together, then they become a visible dandruff unit that sticks in your hair or slides off your chrome dome. Several medical conditions, including bacterial infections, can speed up the shedding process. I suppose if you keep the old bean as smooth as the proverbial baby's butt, you'll scrape off the new dead stuff. But be vigilant. Dandruff never sleeps.
