How Often Should You Get a Haircut? An Honest Answer by Length

Six to eight weeks is the number most people have heard, and it is wrong for about half of them. How often should you get a haircut comes down to three things: how short the shape is, how it is built, and whether the ends are lightened. A pixie loses its shape in three to five weeks. Long hair you are only maintaining can stretch past three months. If you are still deciding which cut to get in the first place, our guide on choosing a haircut that fits your routine walks through that decision in full. This piece answers the narrower question our Ladue, Frontenac, and Webster Groves clients ask once the cut is done: when do you come back?

How often should you get a haircut, by length

Here is the short version. A pixie needs a recheck every 3 to 5 weeks. A bob holds its line for 6 to 8. Shoulder length layers stretch to 8 to 10 weeks, and long hair on a maintenance schedule can go 10 to 14. Curly and textured cuts usually land in the 8 to 10 week range too, since curl hides growth longer than straight hair does. Lightened ends shorten every one of these windows, because lifted hair frays sooner than virgin hair at the same length.

Your texture, your growth rate, and how much heat your hair takes all shift the window. Shorter cuts also grow out faster to the eye. An inch on a pixie changes the whole shape. An inch on hair past your shoulders barely registers.

Why short precision cuts need tighter upkeep

A precision cut is built on a hard line. That line only has a few weeks of growth to work with before it softens. Our precision cuts work the same way whether it is a blunt bob or a sharp fringe. The shorter the shape, the less room growth has to hide.

A pixie that looked sharp on a Friday can look shaggy by week five. Nothing went wrong. The geometry simply depends on the length staying where it was cut.

Here is what actually happens week by week on a hard line. At the root, new growth pushes up evenly, but the nape grows a little slower than the crown, so a shape that started level begins to tilt before it looks obviously long. By week three on a short cut, that tilt is visible in photos even if it is not visible in the mirror. By week five, the sharpest lines, a fringe edge or a graduated nape, have softened into something rounder. Nothing about the hair changed. The angle the cut depended on simply grew out from underneath it.

Bobs sit in the middle. A one length bob holds its line longer than a pixie and shorter than anything layered, because there is nothing softening the growth. You will notice the ends start to flip out or curl under before you notice any real length change. That flip is usually the tell.

Our stylists check a few things before telling a client a trim can wait: whether the internal shape (the layers doing the work under the surface) still moves the way it should, whether the perimeter line is still crisp or has gone soft, and whether the hair is behaving in normal daily styling or fighting the brush and the dryer. If the internal shape is still intact and only the very perimeter has softened, a trim can usually wait another couple of weeks. If the internal layers have grown out enough that the cut is holding weight in the wrong place, that is when we say come in now instead of stretching it.

Long hair, dusting trims, and extensions

Long hair plays by different rules. If you already like your length, you are not really getting a haircut so much as a dusting: a light trim of the very ends to stop splits from traveling up the shaft. That can happen every three to four months, and the length barely moves.

Growing hair out trips people up constantly. The instinct is to skip the salon while you wait. That is the wrong move. Splits do not stop at the tip, they travel, and a small dusting protects the length you are working toward instead of undoing it.

If you wear hand tied or IBE hair, the trim window shifts again. Our row-and-blend check comes from years of IBE certified extension work at the chair, and it starts with the rows themselves: a bead row that has grown too far from the scalp needs to move up before anything gets trimmed underneath it. Once the rows sit correctly, we look at two zones: your natural hair growing in above the beads, and the blended ends where your hair meets the extension hair. The hair above the row often needs its own light trim on a schedule closer to a normal haircut. The blended ends get shaped when they start to look uneven, not on a set calendar. Whether we touch the extension hair itself depends on how it is wearing: if the ends still match the texture and shine of your own hair, we leave them alone. If they are drying out faster than your hair, that is when we shape them back. There is more on what makes extensions look natural day to day, not just on install day. Extensions require a consultation, either in salon or via FaceTime call, so we can see your rows and your growth pattern before quoting any of this.

Trimming around color, and what our water does to ends

Lightened hair needs its own timeline. Lifting removes some of the hair's natural protection, so blonded ends tend to fray sooner than virgin ends of the same length. A client with soft, lived-in color usually wants the trim to land near the toner or gloss visit, so the shape and the shade refresh together.

St. Louis area water is hard, and it leaves mineral buildup on lightened ends. Buildup reads as dull, rough, tired hair, and it sends people in for a trim they do not need. So before our colorists recommend a window, they clarify the hair and look at the ends both wet and dry under direct light. Sometimes the ends are fine and the water was the problem.

Clients driving in from Kirkwood and Des Peres often stack the two services on purpose, because sequencing the trim with the color visit protects both the shade and the shape without adding another trip to a busy week. If you are keeping lived-in color fresh between full appointments, that is the most time-efficient way to do it.

What changes the timeline (and what people get wrong)

A few things push your window shorter or longer than the chart above:

• Fine hair shows split ends faster than thick hair, so it usually needs the shorter end of any range.
• Heat styling and lightening both stress the hair, which means more frequent trims to keep the ends clean.
• Curly and coily textures often stretch a little further than straight hair of the same length, because the curl pattern hides growth longer.
• A cut built on a hard line always needs tighter upkeep than a soft, layered shape.
• Our stylists slide a hand down the mid-shaft before quoting you a window. Heat damage feels evenly rough and dry through the lengths. Breakage from brushes, elastics, and ponytails shows up as short broken pieces clustered in one spot. The first calls for a trim. The second calls for changing what you do at home.
• How you sleep and how often you reach for a hot tool both quietly speed up splitting between visits.
• Hair that has been colored at home tends to arrive with drier ends that fray sooner than hair we glossed in the salon. That is what we see at the chair, not a claim about any product.

The most common mistake is waiting until hair looks visibly rough before rebooking. By then the ends have already split upward, and the trim that fixes it is bigger than the one that would have kept things maintained. The opposite mistake happens too: cutting on a strict calendar reminder no matter what the hair looks like. Your hair does not know what month it is. Let the signals guide the timing.

Frequently Asked Questions

Is six weeks too often for a haircut? Not for most short to medium cuts. If you have a pixie, a bob, or any shape with a defined line, six weeks is often exactly right. Anything longer or layered can usually stretch.

Can I go longer than the chart suggests? Yes, within reason. Long, layered and textured styles hide growth well, so a few extra weeks rarely costs you anything. A precision cut with a hard line will not stretch as gracefully.

Does hair grow back faster after a cut? No. Cutting does not change how fast hair grows at the root. What changes is how visible the growth looks against your shape, which is why short cuts feel like they need constant attention.

Should I trim while I am growing my hair out? Yes. A dusting every three to four months takes off the splitting tips before they travel up the shaft. It protects the length you are working toward instead of setting you back.

Do extensions change how often I need a haircut? They change what gets checked, not just the calendar. Your natural hair above the rows still needs its own trim schedule, while the blended ends only get shaped when they start to look uneven against your own hair.
