It depends on the method, and on which clock you mean. An install lasts about four to eight weeks for tape-ins and sew-ins, three to six months for fusion, and a clip-in set six months to a year or more. The hair itself outlasts the install on re-tapeable methods.
Search this and you will get four answers: four weeks, three months, six months, a year. They are all correct. They are answering different questions.
One number is how long an install stays on your head. The other is how long the hair stays worth wearing. This page keeps them apart.
Two clocks: the install and the hair
Every extension method runs on two clocks. The install clock is how long it stays in before it needs moving, removing or redoing. The hair clock is how long the hair is worth wearing. On tape-ins and sew-ins the install is six to eight weeks, but the hair is re-used across several installs.
Pages that skip this split contradict each other. StyleSeat says clip-ins last up to one day. Perfect Locks says 12 months or more. Both are right: one means one wear, the other the life of the set.
The install clock is set by hair growth and adhesive or thread. Your hair grows, the attachment sits lower on the shaft and the weight hangs from a different spot. The hair clock is set by quality, heat, colour and how you wash and brush it.
| Method | Install lasts | Hair lasts | Sources |
|---|---|---|---|
| Tape-in | 4 to 8 weeks | 3 to 4 re-tapes, about 4 to 6 months | StyleSeat, Luxy, Great Lengths, Perfect Locks |
| Sew-in or machine weft | 6 to 8 weeks | 6 to 12 months | StyleSeat, Luxy, Perfect Locks |
| Fusion or keratin bond | 3 to 6 months | Redone with new hair each time (one source) | StyleSeat, Luxy, Perfect Locks |
| Microlink or bead | 3 to 4 months | Not stated | StyleSeat, Luxy |
| Hand-tied weft | 6 to 8 weeks per move-up, 3 to 4 months in one source | 6 to 12 months | Bombay Hair, Perfect Locks, Christian Michael |
| Clip-in or halo | Removed every wear | 6 months to 12 months or more | Bombay Hair, Perfect Locks, Christian Michael |
Ranges are as each page states them. Sources disagree, mostly sell extensions, and several give no date. Where one source gives a range alone, we say so.
Treat the table as a map, not a promise. For the cost side of each method, see how much hair extensions cost.
Tape-in extensions
A tape-in install lasts about six to eight weeks, then the wefts are removed and re-taped at a move-up. Sources range from four to eight weeks. The hair can be re-taped three or four times, per Great Lengths, so the hair itself lasts four to six months, or longer with care.
Four sources give the install as four to eight weeks, six to eight weeks or up to eight. Cliphair says three to six months for tape-in hair, a 2020 brand blog with no prices. Perfect Locks derives four to six months of hair life from three or four reuses. These are consistent once you split the clocks.
Our own tape-in pages go deeper than a range. How long tape-in extensions last covers the two clocks for tape-ins in full, and how long tape-in tape lasts covers what shortens the adhesive.
In ten years of daily use in our salon, a strong six-to-eight-week hold is what we see with our tape on clean, dry hair. That is practice, not a clinical trial, and it does not carry across to other brands' adhesive.
Sew-ins, hand-tied wefts and fusion
Sew-ins last about six to eight weeks before a tightening or reinstall, with hair reusable for months. Hand-tied wefts are quoted at six to eight weeks per move-up and six to twelve months of hair life. Fusion bonds last about three to six months before they are removed and redone, often with new hair.
Sew-ins are the strictest on time. Luxy recommends a full weave be worn no longer than four months. StyleSeat's price guide, on the other hand, says six to twelve weeks. Take eight weeks as a ceiling for most, and ask your stylist about yours.
Fusion and microlink run longer per install, three to four months in two sources and up to six in another. Luxy says they need repositioning every two to three months. Bombay Hair says K-tips and hand-tied wefts last three to four months per install.
We do not supply fusion, sew-in or hand-tied products, and we have no tested data on them. These are published ranges only. Great Lengths cites up to five months for pre-bonded extensions in suitable conditions, via The Pricer.
- Sew-in: reinstall every six to eight weeks, per StyleSeat and Luxy.
- Hand-tied: move-up every six to eight weeks, per Perfect Locks and Bombay Hair.
- Fusion: redone every three to six months, hair often replaced.
- Microlink: three to four months, repositioned every two to three.
Clip-ins and halos
A clip-in or halo set is worn and removed daily, so it lasts as long as the hair stays in good shape. Bombay Hair says six months to a year or more with care, Perfect Locks says 12 months or more, and Luxy says three to six months, sometimes over a year. It depends on how often you wear it.
Wear count matters more than months. A set worn twice a week and a set worn daily age at very different rates. Luxy suggests washing clip-ins after about 30 wears. Cliphair puts daily use at three to four months, and the others assume lighter use.
Quality is the bigger swing. Christian Michael lists synthetic clip-ins at one to three months and Remy human hair clip-ins at six to twelve. A cheap set that dies in 90 days is not the cheap option.
What shortens the life of any extension
Heat, swimming, big colour changes, rough brushing, poor drying and tension shorten the life of any extension. The Pricer names swimming, frequent heat styling and significant colour changes. Luxy adds brushing wet hair. Tension at the root is the one that harms your own hair, not just the extensions.
Two of those shorten the install, not the hair. Oil and wet bonds make tape slip. A matted nape makes a move-up longer. The other three shorten the hair itself, because heat, colour and brushing wear the fibre.
| Habit | Shortens | Applies to |
|---|---|---|
| Oil or conditioner at the root | Install | Tape-ins |
| Bonds left wet | Install | Tape-ins, fusion, microlinks |
| Brushing wet hair | Hair | Tape-ins, clip-ins, wigs |
| Frequent heat styling | Hair | All human-hair methods |
| Large colour changes | Hair | All human-hair methods |
| Missing the move-up | Install and your hair | All semi-permanent methods |
Habits drawn from The Pricer and Luxy for hair life, plus salon practice for tape-in installs.
For tape-ins specifically, how to make tape-in extensions last longer ranks the habits by impact.
What the two clocks mean for your budget
The install clock sets how often you pay for labour. The hair clock sets how often you pay for hair. Tape-in hair re-taped three or four times means two to three hair purchases a year at most, while fusion redone every three to six months with new hair means two to four. Labour repeats in both.
The arithmetic: Perfect Locks puts tape-in hair at four to six months. Twelve months divided by six is two purchases, divided by four is three. Its fusion figure of three to six months, with new hair each time, gives two to four. Those are seller estimates, so use them as a shape, not a quote.
Clip-ins flip the picture. There is no install clock, since you fit them yourself, so the only recurring cost is replacing the set. At six to twelve months of hair life, that is one or two purchases a year, with no labour at all.
Put the numbers beside the prices in how much hair extensions cost before you choose. A method with a short install clock and a long hair clock, such as tape-ins, is mostly paying for labour. One with a long install clock and short hair clock, such as fusion, is mostly paying for hair.
Signs it is time to replace or redo
Replace hair when the ends are thin, the weft base is coming apart or the fibre is matted despite care. Redo an install when it has grown out, a bond is loose or the weight pulls. Do not wait for failure. Past the install interval, matting and tension rise whatever the hair quality.
- Ends look thin or see-through next to your own hair.
- The weft seam or base is frayed or splitting.
- A knot at the bond will not separate with your fingertips.
- A tab or bond has slid, lifted or feels loose.
- The attachment sits well below your scalp.
When it is not a lifespan question
Pain at one spot, a headache, tenderness that worsens, redness at the bond line, or sudden shedding means stop. The American Academy of Dermatology says pain or a headache means the style is too tight, and traction alopecia can be permanent. See a licensed stylist and a dermatologist. This is guidance from the chair, not medical advice.
What these numbers cannot tell you
These lifespan figures cannot predict your hair. Growth rate, scalp oil, wash habits, hair quality and stylist skill all move them. We found no independent study of extension lifespans. Every range here is a seller or salon statement, so use them to set expectations and ask your own stylist for yours.
The sources disagree on purpose, in the sense that each describes a different client. Where a source gave no date, we say so. Some of these pages date from 2019 and 2020. Use the middle of a range, not the edge.
We make tape and remover for one method. If you wear tape-ins, a move-up every six to eight weeks needs fresh tabs. Replacement Tape Tabs are $45 for 60 tabs, 30 sandwiches, and they work with any brand's double-sided wefts: strip the old tape and re-tab with ours.
What this guide is based on
Lifespan ranges are quoted as published on pages we opened on 12 November 2026 from retailers, a salon owner and an aggregator, and we found none that cite independent testing. The tape-in notes reflect ten years of daily salon use at Vanity Hair Salon with Jaci Finch, a licensed cosmetologist, not a controlled study. See how we test for how we handle claims.
Questions we get asked
How long do hair extensions last?
The install lasts about four to eight weeks for tape-ins and sew-ins and three to six months for fusion. Removable clip-ins can last six months to a year or more. The hair itself often outlasts the install on methods that can be re-taped, re-sewn or moved up.
How long do tape-in extensions last?
About six to eight weeks per install, with sources ranging four to eight. The hair can be re-taped three or four times, per Great Lengths, so it can last several months across installs. Oil at the root, wet bonds and skipped move-ups shorten the install.
How long do clip-in extensions last?
Sources say three months to over a year. Perfect Locks says 12 months or more, Bombay Hair six months to a year, and Luxy three to six months. Quality and how often you wear them decide it: synthetic sets can be done in one to three months.
How long do sew-in extensions last?
About six to eight weeks per install according to StyleSeat and Luxy, after which they are tightened or redone. Luxy says a full weave should not be worn longer than four months. The hair can be reused for months, so ask your stylist what she expects from yours.
How long do fusion extensions last?
Sources give three to four months, up to three months, or three to six. Many redo fusion with new hair each time, so budget for the bonds and the hair together. Luxy says fusion and microlinks need repositioning every two to three months as your hair grows.
Which hair extensions last the longest?
Clip-ins and halos show the longest published hair life, six to twelve months or more, if worn lightly. Hand-tied wefts are quoted at six to twelve months of hair life too. The install interval is a separate number, and it is shorter on semi-permanent methods.
How many times can you reuse hair extensions?
Tape-in hair can be re-taped three or four times, per Great Lengths. Perfect Locks puts new hair at every four to six months on that basis. Cheap hair may not survive a second install, so check the weft base and ends at every move-up before you re-tape.
How do I make hair extensions last longer?
Keep oil off tape, dry the bonds after washing, brush from the ends up, limit heat and book move-ups on time. Avoid brushing wet hair. Tension is the one to watch most closely, since a style that pulls harms your own hair, not just the extensions.
Can I leave extensions in longer than the recommended time?
It is not advised. Past the interval the attachment sits lower, weight hangs from longer sections and matting rises. For tape-ins, move up by eight weeks. If a bond feels tight, sore or itchy before then, have it taken out and see a licensed stylist.
Do extensions last longer on certain hair types?
We found no independent data on this. Hair growth rate and scalp oil change the install interval, since faster growth moves the bond down sooner. Cliphair says tape can slip on oily or greasy hair, so people with oily scalps should plan earlier move-ups.
