Short answer. The hours right after a line-up decide how it holds up. Rinse the loose hair, keep the fresh edge clean, skip the harsh alcohol splash, and moisturize the skin along the line. That is how you keep the edge sharp and the skin clear.

A crisp line-up is the whole look. It frames your face, and when it is fresh you feel it. Then two days later the edge is fuzzy, or worse, there is a row of little bumps sitting right along the line where the razor ran. That is not bad luck and it is not your barber. It is what happens in the hours after you leave the chair, when the skin along a freshly edged line is at its most exposed. Handle those hours and your line-up looks like day one for most of the week.

The first hour after the chair

Your barber ran a sharp blade right along the edge of your hairline and beard, which means the skin there just took a close pass and is a little raw. The first thing to do when you get home is a gentle rinse with cool water to clear off the loose clipped hair and any product left behind. Cool water settles the skin down. Skip the hot water for now, because heat opens things up and can leave the fresh line more irritated.

Keep your hands off the line for the first day. Every time you rub or scratch at a fresh edge, you are dragging grime across skin that just got shaved, and that is a fast path to bumps right along the line.

Skip the burning splash

Plenty of men reach for a strong alcohol aftershave the second they get home because it stings and feels like it is working. On a fresh line-up that sting is the sound of your skin drying out. Harsh alcohol strips the skin along the edge and can leave it tight, flaky, and more likely to bump. If you want an aftershave, choose a gentle, alcohol-light one, or skip it and go straight to moisturizer.

The goal after a line-up is calm skin, and calm skin is moisturized skin. A burning splash works against that every time.

Moisturize the line

The edge of a line-up is skin that just got shaved close, so treat it like any freshly shaved skin. After you rinse and pat dry, put a light, fragrance-free moisturizer along the hairline and beard edge. This keeps the skin from drying out and roughing up, which is what turns a clean line into a bumpy one over a couple of days.

For the beard part of the line, a few drops of beard oil worked down to the skin does double duty: it moisturizes the skin and keeps the hair right up to the edge soft. Do this the night of the cut and again the next morning while the line is settling in.

Protect the fresh edge outdoors

A fresh line exposes a strip of skin right at your hairline that usually sits under hair. That strip has no shade for the first few days, and sun on freshly shaved skin is exactly how you set uneven tone deeper along the edge. If you are out in daytime sun after a cut, keep SPF on the forehead and the exposed line. It is the same reason your neck darkens over time from shaving, and it is easy to head off.

Keep the line clean day to day

Between cuts, a gentle daily wash and a light moisturizer along the edge keep the skin clear so the line stays looking sharp. If you tidy the edge yourself between barber visits, use a clean, sharp blade, go with the grain, and moisturize right after, the same as you would any shave. A line-up is only as sharp as the skin under it lets it be, so keep that skin calm and your edge holds.
