If your extensions feel looser than they did a few weeks ago, you're not imagining it. Your hair grows, the extensions grow out with it, and at some point the row sits too far from your scalp to look right or stay comfortable. Here's what actually decides your timing, whether you're wearing them or installing them.
Most people fall into a six to eight week window, but that range shifts depending on what's holding the hair to your head.
Tape-ins usually need attention every six to eight weeks. The tabs travel down as your hair grows, and once they've moved past about half an inch to an inch from the scalp, they start to show and they start to tug. Hand-tied and beaded wefts run a similar schedule, often seven to eight weeks, because the beads slide down the same way. Fusion and micro links can sometimes stretch a little longer, closer to eight to ten weeks, since each bond is small and moves independently. Clip-ins are the exception. They come out at night, so there's no fill at all. You reposition them yourself every time you put them in.
None of these numbers are a rule you can set a phone alarm to. They're a starting point. Your own hair decides the rest.
Two people can leave the same appointment on the same day and need their next fill weeks apart. That's because hair growth isn't uniform from person to person.
The average scalp grows hair at roughly half an inch a month, according to the American Academy of Dermatology. Some people run faster than that, some slower. If you're on the faster end, your extensions will slip lower on the strand sooner, and you'll feel the weight pulling before someone with slower growth does. The point isn't the exact number. It's that "six weeks" is a guess until you learn your own pattern. After your first two fills, you'll have a real sense of your timing, and that's the schedule worth trusting.
Your hair will tell you before the calendar does. Watch for these.
The row starts to show. When you part your hair or pull it back and you can see the tabs, beads, or bonds sitting away from your scalp, they've grown out too far. A well placed row should stay hidden, and when it stops hiding, that's your cue.
You feel tension. Grown-out extensions pull. The weight that used to sit close to your head is now hanging lower, and that added use tugs on your natural strands. If your scalp feels sore or you notice pulling when you brush, don't wait it out.
Tangling gets worse near the attachment. As extensions grow out, your natural hair and the extension hair have more room to twist around each other close to the root. If you're fighting knots at the top that weren't there a few weeks ago, the bonds have moved.
You're losing shed hair inside the row. Everyone sheds around 50 to 100 hairs a day. Normally those fall out. When your hair is attached in a weft or bond, the shed hairs get trapped and collect at the base. Left too long, that buildup can matte. A timely fill clears it out.
Pushing your fill way past when it's due isn't just a cosmetic problem. It puts stress on your natural hair, and that's the part worth protecting.
When bonds or wefts sit far from the scalp, all their weight pulls on a small section of your own strands at an angle they weren't installed at. That constant tension is hard on the hair follicle over time. It's also where trapped shed hair turns into matting, which is uncomfortable to remove and rough on the hair when it finally comes out. The whole point of quality extensions is that they should feel good and leave your natural hair healthy underneath. Skipping fills to save money or time works against both.
Going too soon has a smaller downside, mostly wasted appointments and cost, but there's rarely a reason to fill before the hair has grown enough to justify moving the row.
The best time to set expectations about fills is before you ever install a single weft. Clients who understand the maintenance rhythm up front book their fills on time, and clients who book on time keep healthier hair and stay happier with their extensions.
At the install, walk your client through their method's typical window and explain that you'll dial in their exact timing after the first couple of fills. Feel their hair growth, look at how their row has moved, and adjust. A client with fast growth might come in every six weeks while another sees you every eight, and naming that difference out loud keeps them from thinking something's wrong.
Book the next fill before they leave. Not as a sales push, just as part of the service. A client who walks out with a date already set is far less likely to stretch past when their hair needs attention. And when they do come in on schedule, your removal and reinstall go faster, the hair stays in better shape, and they see you as the person who keeps their extensions looking right, not just the person who put them in.
Start with your method's window, six to eight weeks for most, then let your own hair fine tune it. Watch for the row showing, the tension, and the tangling instead of waiting for a specific date. When two of those signs show up, it's time, even if the calendar says you've got another week. Your extensions look their best and your natural hair stays healthiest when the row stays close to your scalp, and staying on schedule is the simplest way to keep it there.
