How long do lash extensions last?

An extension lasts as long as the natural lash it's on, so a set never falls off all at once. It thins out as your own lashes shed, and most people come back for a refill every two to three weeks.

By Amy Sun, owner of SQ Beauty Spa

Why lash extensions fall out

Every extension is bonded to one of your own lashes, and it stays exactly as long as that lash does. Your natural lashes don't all grow on the same schedule. Each one is at its own point in a cycle of growing, resting and shedding, so on any given day a few are new and a few are ready to fall. You shed some every day, whether you wear extensions or not.

When a natural lash sheds, its extension leaves with it. That's why a set doesn't drop off on a particular day: it thins out gradually, and around two or three weeks the line starts looking thinner in the mirror. In the meantime new lashes grow in bare, without an extension on them.

So the honest answer is that each extension lasts as long as the lash under it, and the set as a whole needs filling every few weeks to keep looking full.

When to come back for a refill

Most people come back every two to three weeks. At SQ Beauty Spa a refill is priced by how much has grown out since your last visit, in two windows counted from the day you leave: days 3 to 14, and days 15 to 27. Come back sooner and you'll pay less, because there's less to fill in.

Whichever set you wear, the extensions shed with the same natural lashes, so the rhythm is much the same from one set to the next. What changes is the price and the time in the chair:

Refill price and appointment time by set
Set Refill, days 3–14 Refill, days 15–27 Full set
Classic $5045 min $601 hr $891 hr 30 min
YY $6045 min $701 hr $991 hr 30 min
3D / Hybrid $801 hr $901 hr $1191 hr 30 min
Design Wispy $1001 hr $1101 hr 30 min $1392 hr
6D Volume $1201 hr 20 min $1301 hr 30 min $1592 hr
9D Volume $1401 hr 30 min $1501 hr 40 min $1792 hr

When a refill becomes a new set

Past day 27 there's usually too little of the old set left to fill, so the appointment is priced as a new full set. If you know you're going to be away longer than that, ask us about a removal and start fresh when you're back. Removal is $25.

Wearing a set that was done somewhere else? Sometimes it can be filled. It depends what was used, how it went on and how much is still there, so send a clear photo of your lash line before you book anything and we'll tell you straight. Text (770) 688-9230

What makes extensions fall out sooner

Four things decide how long a set lasts: the work, your own lash cycle, how oily your skin runs, and what you do at home. You can only change the last one, and most of it is small:

  • Keep them dry for the first 24 hours while the glue finishes setting. No pool, no sauna, no steam.
  • Keep oil away from the lash line. Oil dissolves the glue, so check balms, removers, eye creams and sunscreens.
  • Skip mascara, waterproof most of all. Taking it off means rubbing, and rubbing is what pulls extensions loose.
  • Sleep on your back if you can. Face-down sleeping thins a set faster, and a silk pillowcase helps if you can't change how you sleep.
  • Brush them every morning, and wash them with a foaming lash cleanser every two or three days. Clean lashes hold on longer.
  • Hands off. Pull one off and your own lash comes with it. If one's bothering you, call us instead.

Chlorine, salt water and sweat shorten retention a little, and so does steam and cleanser around the eye. That's why we book a facial and a lash set on separate days.

Quick answers

How long do eyelash extensions last?

Each extension lasts as long as the natural lash it's bonded to. You shed a few of your own lashes every day, so a set thins out gradually instead of falling off at once. Most people come back for a refill every two to three weeks.

How long can I go without a refill?

There's no day they all fall off, but the set keeps thinning. Refills are priced from day 3 to day 27. Past day 27 there's usually too little of the old set left to fill, so you'll pay full set price again.

What makes lash extensions fall out faster?

Oil near the lash line, water or steam in the first 24 hours, rubbing (taking off mascara counts), sleeping face-down and picking at them. Oily skin, chlorine, salt water and sweat shorten retention a little too.

How much does a lash refill cost?

Between days 3 and 14 a refill is $50 to $140, depending on your set. Between days 15 and 27 it's $60 to $150.
