How Often Should You Get a Haircut?

"Every six weeks" is the answer everyone repeats and almost nobody needs. The right interval depends on one thing more than any other: how much of your haircut is a hard line. A cut built from lines needs redrawing constantly. A cut built from shape can be left alone for months.

Why the standard answer is wrong

Hair grows at roughly a centimetre a month, and that rate barely varies between people. So the interval is not really about growth speed. It is about how visible a centimetre of growth is on your particular cut.

A skin fade is a gradient that ends at zero, so a millimetre of regrowth is measurable at the bottom edge. A layered mid-length cut has no edge at all, which is why it survives three months. Same growth, completely different clock.

The actual intervals

What to expect if you want the cut to still look like the cut, rather than merely acceptable.

Two adjustments worth making to those numbers. Fine hair shows a growing edge sooner than thick hair, because there is less bulk to hide it. And coily or tightly curled hair hides length changes best of anything, which is why the intervals at the bottom of that table are months rather than weeks.

The split-ends question

If you are growing your hair, the advice to trim every six to eight weeks "to make it grow" is backwards: cutting the ends has no effect on growth at the root. What it does do is remove damage before it travels, and a split that runs upwards costs you more length than the trim would have.

So the honest version: if your ends are in good condition, you can go far longer than six weeks while growing. If they are splitting, a small trim now preserves length rather than sacrificing it. Judge the ends, not the calendar. The AAD's everyday hair care guidance is a reasonable baseline on what actually causes that damage.

How to stretch the gap

Four habits, in order of how much time they buy.

Ask for a taper instead of a hard line. A blocked neckline shows regrowth within a fortnight; a tapered one blurs it for weeks. This single request is worth more than the other three combined.

Own a trimmer and tidy the edges. The neckline and around the ears are what read as scruffy, long before the actual length does. Five minutes at week three buys a fortnight.

Ask how the cut grows out, at the appointment. A good barber will tell you which week it starts to go and what to do about it, and will happily cut a version that ages better if you say that is what you want.

Tell them your real interval. "I get this cut every eight weeks" changes how they cut it. A cut designed for a four-week cycle worn for eight weeks is not the same haircut.

Pick the cut for the cadence, not the other way round

The most useful reframe in this whole subject: your appointment frequency is a constraint, so choose a cut that fits it rather than choosing a cut and then failing to maintain it. If you know honestly that you go three times a year, a skin fade is the wrong purchase regardless of how good it looks on day one.
