The most common answer you will hear is every four weeks. It is not wrong, but it is not really an answer either, because the honest one is: it depends on the haircut you are trying to maintain. A skin fade and a grown-out textured crop are different commitments, and treating them the same is how a good cut ends up looking like an accident by week five.
Here is how we would actually break it down.
Short and sharp: every 2 to 3 weeks
If your cut relies on contrast, a skin fade, a tight taper, sharp lines around the neck and ears, then the freshness is the haircut. These styles look their best in the first ten days and visibly age from there. Two to three weeks keeps them looking deliberate. Past four, you are not maintaining the style, you are waiting to restart it.
Classic short cuts: every 4 to 5 weeks
Crops, French crops, shorter scissor cuts and anything clipper-and-scissor blended without going to skin sits happily on a four to five week cycle. The shape softens gradually rather than collapsing, so you have more room before it stops behaving. This is the cycle most of our clients are on, and it is what the four-week rule of thumb is really describing.
Medium length: every 5 to 7 weeks
Once the hair has genuine length on top, the cut is about shape rather than edges. Weight builds slowly, and a good cut is designed to grow into itself for the first few weeks rather than straight out of shape. Five to seven weeks keeps the structure without ever letting the hair get heavy and flat.
Longer styles: every 8 to 12 weeks, without skipping
The biggest myth in men's hair is that growing it out means staying away from the salon. It is exactly backwards. Longer hair still needs its internal weight managed, its ends kept healthy and its shape steered, otherwise you end up with the triangle silhouette that makes most people give up and cut it all off. Eight to twelve weeks is right for maintaining length; if you are actively growing, we would still want to see you inside ten. We wrote a separate guide to growing your hair out without losing its shape, because it deserves one.
Three things that shift the schedule
How fast your hair grows. Half an inch a month is the average, but it is only an average. If your fade disappears in a fortnight, believe your mirror over the calendar.
Your tolerance for the in-between. Some people enjoy week-three softness; some people feel scruffy on day ten. Neither is wrong. Book to your own threshold, not someone else’s.
What your week demands. If you are client-facing every day, or you have a run of events coming, it is worth booking so the cut peaks when you need it. A haircut looks its absolute best two or three days in, once it has settled. It is why grooms come in a few days before the wedding, not the morning of.
The simplest way to get it right
Ask your stylist at the end of your appointment. They have just cut your hair; they know exactly how it is going to behave in week three and when it will stop cooperating. At P2 every appointment ends with styling advice, and the honest answer to "when should I come back?" is part of that. Then book it before you leave the chair. Future you, staring down a big week with a fresh cut already in the diary, will be grateful.
Every appointment starts with an in-depth consultation.
