1. The high and tight
How to get it: Your barber should know it by name. There’s room for variation, but usually it goes from the lowest setting on electric clippers and fades up, leaving the top long enough to work in some pomade.
2. The crew
How to get it: This is a super simple, no-muss, no fuss haircut done exclusively with clippers. Ask for a fade from short to not-so-short using a high clipper setting on the top and “corners”.
3. The sweepback
How to get it: Ask your barber to clean up the back and sides and leave it long on the top. Style with light gel or pomade. Your hair should still be soft to the touch when done.
4. The disconnect
How to get it: Have your barber use clippers all the way up the sides, leaving it very long on top, without any fade – hence the name.
5. The slacker
How to get it: The genius of this cut is that it doesn’t look like a haircut at all. Ask your barber for a trim with very subtle layering. Too blunt and you’ll look like a teenage girl, too layered and you’ll look like Rachel from Friends.
6. The buzz cut
How to get it: Like the Crew, but your barber will use one setting over the entire head. Shahid Kapoor’s in Haider was about a half inch.
7. The undercut
How to get it: Shave the back and sides with clippers, fading up to the “round” of the head. The top is left long. Style with pomade or wax.
