About: A KNACK (어냅) is a cut-focused hair salon on Seongsu-il-ro 1-gil, in the middle of Seongsu's café-and-boutique cluster. The shop is known for structural, sculptural styles — two-block cuts, blunt bobs, hime cuts — finished with highlights and braiding for emphasis, under stylist Kim Ji-eun, who frames the salon's approach as blending newness with everyday wearability.

Beyond cuts, A KNACK also runs a scalp head-spa treatment aimed at relieving buildup and hair fatigue, rounding it out beyond a straightforward cut shop. Hours run 10am–7pm, closed Mondays and Tuesdays, with booking through Instagram rather than a dedicated site.
