In short: keratin bonds and nano/mini tips are typically refreshed every 10–14 weeks, and seamless wefts every 10–12 weeks — though your individual hair growth rate and how closely you follow your aftercare routine both affect this. There's no single fixed number that applies to everyone.
“How long do extensions last” depends on the method, your natural hair's growth rate, and how closely you follow your aftercare routine. What follows is a realistic guide, not a guarantee — we'll confirm your specific schedule at your fitting.
Typically 10–14 weeks before a maintenance appointment is needed, as the bond grows away from the scalp along with your natural hair.
Also typically 10–14 weeks — the small ring or bond needs repositioning closer to the root as your hair grows.
Generally refreshed every 10–12 weeks. Individual growth rate makes some variation normal, which is why we check in with every client rather than working to a fixed calendar.
Following your aftercare routine — the right shampoo, gentle brushing, tying hair up at night — helps you get the full recommended window out of a set. Skipping maintenance appointments doesn't make extensions last indefinitely; it simply puts more strain on your natural hair as the gap between the attachment point and your scalp grows.
With good care, the hair used in keratin bonds and nano tips can often be reused across two or three maintenance cycles — worth raising at your appointment if that's a priority for you.
As a general guide: if it's been more than 14 weeks for bonds or nano tips, or 12 weeks for wefts, it's time to book. If in doubt, get in touch and we'll advise.
Climate has a smaller effect than aftercare habits, though heat, humidity and chlorine exposure (from holidays or swimming) can affect bonds and rings slightly — we'll advise on this seasonally if relevant.
Nothing dramatic happens overnight, but the longer you leave it, the more strain is placed on your natural hair as it grows away from the attachment point. Book as close to your recommended window as you can.
Yes — the right sulphate-free shampoo, heat protectant, and gentle brushing routine make a genuine difference. See our full aftercare guide for specifics.
