Just dont start using a dandruff shampoo- so many people think dry scalp is dandruff when dandruff is actuall greasy flakey scalp. As far as treating it goes, I found that washing my hair more often- every day instead of every other day, worked wonders for me when I get the occasional dry's- and I also make sure I dont get any hairspray on my scalp; the alcohol in styling products only makes it worse.
