Personally, I think my dandruff is caused by a history of eczema, shitty New York tap water, and chronic bad juju. After my traumatic episode, I searched the racks of Duane Reade for any type of drugstore-brand scalp treatment, when I came across a familiar face: tea tree oil.
From Midtown or the Village, take the F or D trains that run down Sixth Avenue from Central Park to Washington Square or the N or Q trains that run down Broadway to Canal Street. All four of these trains will take you directly to Coney Island in Brooklyn.
Take the F train to York Street: Option 1: Transfer to the B62 at York and Gold Streets going toward Long Island City. Get off at Cumberland Street OR Clinton Avenue. Walk one block to Flushing Avenue.
