The frequency of bang trims depends on individual factors, including hair growth rate, hair texture, and personal preferences. For faster-growing hair or bangs that grow unevenly, trims may be necessary every 2-4 weeks. Thicker, coarser hair tends to grow slower, so trims may be less frequent. Consider your desired style when trimming bangs: blunt bangs may require more frequent trims to maintain the straight edge, while choppy or textured bangs can handle longer intervals between trims.
