By definition, hair trends tend to be short-lived affairs. Just look at the curtains of the 1990s, the glam-rock perms of the early 1980s and the rock ‘n’ roll sideburns of post-war America for proof.
At best, most tonsorial trends have a shelf life of around five to ten years before they become laughable and cringe-inducing. So for a hairstyle to stick around for over a century is nothing short of miraculous.
Enter: the undercut. Possibly one of the unlikeliest candidates for timeless status, but a quick flick through the history books tells you all you need to know about its well-established credentials.
