Founded in 2018 in Point Loma, San Diego, QSD Barber Shop anchors Midway Plaza in the Midway District with a walk-in format built around razor fades, flat tops, and beard trims. The shop's shared-floor layout seats multiple barbers cutting simultaneously, a production model shared with nearby Barber Box on Rosecrans that keeps the Point Loma barbering corridor stacked with same-day availability. Flat-top cuts rely on a freehand clipper-over-comb technique to square off the crown, a geometric style that requires the barber to sculpt against the head's natural curvature. Military personnel from the adjacent naval installations make up a steady share of the chair rotation, drawn by a cut menu that maps directly to Department of Defense grooming standards. That base-adjacent clientele overlaps with the walk-in traffic at InterHair down the corridor, though QSD's focus stays on clipper work rather than salon-style scissor cuts. The most technical request in the rotation is a skin-to-one blended fade that tapers the hairline into a razor-finished neck and temple edge-up.
