Buzz cut: one guard, an even head

One length, and the outline has nowhere to hide. A buzz is a single guard over the head, or a small step between the side and the top, cleaned at the neck and the sideburn. There is no fringe to distract from a wobble, no texture to break up a track, no longer top to comb over a thin crown. The shape of the skull becomes the haircut. That is the appeal, and it is the risk. If the head is uneven, the buzz reports it honestly.

Pick the guard by the hair you have, not by a photo of someone with denser hair. A number one on a thin crown shows scalp in a map. A number three can still look clean and keep a little cover. A number two is the middle a lot of men mean when they say "a buzz" without a number. The chair should say this out loud before the first pass, while the hair is still long enough to change the plan. Once the one is on, the three is no longer available until you grow it.

The neck and the sideburn are the actual haircut. An even buzz with a chopped sideburn looks unfinished, as if the appointment ended early. Decide where the sideburn stops: mid-ear, the top of the ear, or blended off. Decide whether the neck is rounded into the natural hairline or blocked into a square. A block looks sharp for a few days and then frames the neck in a box while the buzz above it stays soft. Most heads want the natural line followed, with stray hair removed and the corner left uninvented.

Balding at the crown is more honest with a shorter all-over buzz than with a long top combed over it. The shorter cut makes the head one shape. The comb-over makes a diagram of the thin spot, because the eye follows the direction of the hair you are using as cover. If that honesty is what you want, say the shorter guard and mean it. If you still want cover, do not ask for a one and hope. Ask for the longest buzz that still looks even, and accept that even includes the crown.

Clipper tracks come from pressure and from going over the same place until the scalp is polished in stripes. A buzz should be a light, overlapping pass with the grain, then a detail pass only where the first one missed. If your skin reacts to close clippers, say so. A slightly longer guard is a better solution than a harder hand. Recurring bumps, or a scalp that stays sore past the ordinary tightness of a fresh cut, belong with a dermatologist. The next visit can be a longer guard. It cannot be a diagnosis.

You can maintain the neck at home if you have a steady hand, a guard, and two mirrors. The goal is stray hair, not a new haircut. The first time, leave it. A nick on the neckline is brighter than the buzz, and it heals slower than the hair grows. Do not take the guard off to "sharpen" the sideburn. Bare blades in a bathroom are how a clean buzz gains a stair step beside the ear. If the outline bothers you that much, the outline is a five-minute visit, not a project.

The first week looks as intended, which is the point of a cut with no styling. In the second week it is still a buzz, just softer. By the third week a one has become something closer to a two, and a three has become long enough to lie in directions. That is still wearable. It stops being the buzz you booked when the sideburn turns into a patch and the neck fills the collar. Two to four weeks, depending on the guard and how fast the hair grows, is the real range. Coarse hair on a one asks for the short end of it.

Sun on a freshly buzzed scalp is not theoretical in Miami. The crown and the top of the ears burn while you are still congratulating yourself on the low maintenance. A hat for the first days, or sunscreen on the scalp the same afternoon, belongs with the haircut. Sweat under a hard hat does the same irritation more slowly. Rinse. Do not scrub the scalp with a nail to "exfoliate" a three-day buzz.

If you want a step, say how big. "Two on the side, four on top" is a buzz with a plan. "Same length all over" is the stricter version, and it demands a rounder, more careful outline because there is no longer top to make the head look shaped. Either one should be agreed before the clipper starts at the bottom, where people often go shorter than they meant and then have to chase the rest of the head down to match. Start where you are sure. The rest of the head can follow a length. It cannot follow a guess.
