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.
Penn Station is also a quick walk from the hotel. At Penn Station, you can catch the NJ Transit train (takes you to the Jersey Shore and other towns within Jersey), the Long Island Rail Road (towns on Long Island and the Hamptons), and Amtrak trains which take you to select destinations along the East Coast.
