My grandfather used to do his hair sortof like Patrick Bateman in Am PSycho, but his hair was shorter in the back.
What you do is get your hair cut shorter in back and cut about an inch off your bangs. Then take a little bril cream and water and slick the front part of your hair back over your head.
If you go to most salons, you can show someone how you want your hair to be and continue to go to the same stylist every three weeks and they can help you with the look. Hope this helps
BTW, American Psycho is one of my favorite movies and I really enjoyed the book too, which is much different. Also fun fact: Leo Dicaprio and stephen baldwin were both considered for the role.
