On Av. Rep de Panama, near the corner of Angamos (in Surquillo) - just across Panama in front of Ace (Maestro) Home Center. Wait for the guy with the mustache. 5 soles, excellent hair cut, scissors, razor, just tell him what you want. He's one of those guys that knows how to read the shape of your head and the direction your hair grows to give you the right cut - he's the only person we've found that can cut my son's hair in a way that doesn't leave it sticking straight up like Alfalfa from the Little Rascals.
