What is the difference between a tapered and blocked neckline?

A tapered neckline gradually fades from the haircut length down to nothing, with no hard line at the bottom — it looks natural and grows out well. A blocked neckline has a sharp, straight horizontal line across the nape with everything below shaved clean. Blocked looks crisp but shows regrowth faster.

Which neckline shape is best?

Rounded necklines are the most popular and universally flattering — they follow the natural hairline curve. Squared necklines suit angular faces and structured cuts. Tapered necklines are most natural and low-maintenance. Blocked necklines give the boldest look but need the most frequent maintenance.

How long does a neckline cleanup take?

A simple neckline cleanup takes 5-10 minutes. A short taper with trim takes about 5 minutes. A medium taper with blending takes 8 minutes. A longer, more gradual taper takes up to 10 minutes. Add time if a razor finish is included for a defined edge.

How often does a neckline need maintenance?

Natural tapered necklines grow out gracefully and need attention every 3-4 weeks. Trimmed/defined necklines show regrowth in 1-2 weeks. Shaved/blocked necklines show stubble in 5-7 days. Many clients pop in between full haircuts for a quick neckline cleanup to keep things sharp.
