Men's hair styles have seen remarkable changes over the decades, with trends like the buzz cut, pompadour, and undercut becoming popular choices. The quiff and fade offer modern, sleek looks, while the crew cut and side part remain timeless. Styles like the man bun, top knot, and textured crop cater to longer hair. Curly hair can be styled with a taper fade or afro, while straight hair suits a slick back or French crop. The Caesar cut, bowl cut, and Ivy League provide versatile, professional options. Beard styles and hair products like pomade, wax, and mousse enhance these looks.
