Every dude with hair uses “product” (Crew Fiber or Boost Powder, hair spray, Batiste dry shampoo, Brylcream…something) or at the very least a comb. To give it an intended attitude, a little shape. Otherwise your hair just flops and scatters out all over the place.
Tom Cruise definitely applied hair shapers and holders in the early days (Risky Business, The Firm, A Few Good Men) but not over the last few years. Nowadays he pretty much wears a raggedy-ass soup bowl. An odd way to go.
