Lash extension aftercare

Whether your set still looks full in week three is decided in your bathroom, not in our chair. Here is the whole routine, and the three things that quietly destroy a set.

Every new client goes home with shampoo and a brush

The short version

How to clean lash extensions, and what ruins them.


Clean your lash extensions daily with a dedicated lash shampoo and a soft brush, keep every oil-based product away from the lash line, and stop sleeping face-down. Those three habits account for most of the difference between a set that needs refilling at two weeks and one that holds to three. With a standard adhesive, keep lashes dry for the first 24 hours; with the LED-cured bond that wait disappears. Nothing — no product, no adhesive — makes a set outlast your natural shed cycle.

The first 24 hours

Only one rule, and only if you skipped the LED bond.


Standard lash adhesive keeps curing for 24 to 48 hours after you leave. In that window, water and steam can soften a bond that has not finished setting. That is the entire reason for the rule — not fragility, chemistry.

  • No water on the lashes, no steam, no sauna, no hot yoga, no swimming.
  • No eye makeup and no cleanser on or near the lash line.
  • Try not to cry, which is advice nobody can follow but we are obliged to give.
  • Sleep on your back if you can manage it on the first night.

With the LED-cured bond, the cure finishes under the lamp during your appointment, so none of the above applies — shower, train or swim the same day. It is $20 on any set, and that is the only thing it changes.

After 24 hours

Live normally. Clean them.

From day two there is nothing to avoid except oil, mechanical force and waterproof mascara. Swimming, the gym, saunas, rain, washing your face properly — all fine, all expected, and none of them is why a set goes patchy.

What is why: a lash line that never gets cleaned. Sebum, makeup and skincare build up at the base of the extensions and break the bond down from underneath. People who think they are protecting their set by not touching it are the people whose sets fail first.

The daily routine

Ninety seconds, once a day.


Every new client leaves with a lash shampoo and a brush. This is what they are for, and it is not complicated — it is just non-negotiable.

Step one Foam it A pump of lash shampoo on a clean fingertip or the brush, worked gently along the lash line with the eye closed. Side to side at the base, not up and down the length.
Step two Rinse properly Lukewarm water, cupped in your hand or from the shower at low pressure, until there is no foam left. Shampoo residue left at the base is as bad as the oil it removed.
Step three Dry and brush Pat with a lint-free cloth or let them air dry, then brush through with the spoolie once they are dry. Brushing them wet pulls at the bond.

Do it at night, every night. A set is dirtiest at the end of the day, and sleeping on a day's worth of sebum and makeup build-up is exactly the condition that breaks bonds down. If you only do it sometimes, do it at night.

What actually kills a set

It is almost never the adhesive.


When a client comes in at two weeks with a line that looks like week four, it is one of these five, in roughly this order of frequency.

The habitWhat it doesInstead
OilCleansing balms, oil makeup remover, rich eye cream and some SPFs dissolve cyanoacrylate. The bond fails at the base and extensions slide off intact.Read the ingredients on anything used within an inch of the lash line. Water-based or oil-free, always.
Sleeping face-downMechanical. Extensions get crushed, bent and twisted against the pillow for seven hours, and twisted lashes get pulled out or fall early.Back or side, and a silk pillowcase. This one change buys more retention than any product.
Touching and pickingRubbing your eyes, pulling at one that is poking you, playing with them while you think. Each pull takes a natural lash early.If one is twisted or bothering you, brush it. If that does not fix it, text us — do not pull it.
Not cleaning themBuild-up at the base breaks the bond from underneath, and it also causes the itchy, irritated lash line people blame on adhesive allergy.Daily, at night, with lash shampoo. Ninety seconds.
Waterproof mascaraImpossible to remove without rubbing and solvent, both of which take extensions with them. Clumps the fans permanently.Nothing. That is the point of the set. If you need more darkness, go up a density tier.

Also worth knowing: shed rate is seasonal. Most people lose more lashes in spring and autumn, and almost everyone sheds more during pregnancy or after a change in medication. If retention drops suddenly and nothing in your routine changed, that is usually why.

The real question

Do lash extensions damage your natural lashes?


Properly applied, properly weighted and properly removed — no. Lash extensions sit on the lash and shed with it. The damage people describe is real, but it has three specific causes, and all three are avoidable.

Cause one Too much weight An extension longer or thicker than the natural lash can carry puts the follicle under constant load. The lash sheds early and the next one grows in weaker. This is why mapping happens before anything is applied, and why we will refuse a density your lashes cannot hold.
Cause two Stickies Two natural lashes bonded together, or an extension placed across both. Because lashes shed individually, one pulls the other out before it was ready. This is an application fault and it is the main reason we will not refill over someone else's bad set.
Cause three Pulling them off At home, with fingers, with tweezers, or with oil and hope. Lash adhesive is stronger than a lash follicle, so the lash comes off with the extension. This is the single biggest cause of "extensions ruined my lashes."
The fix Removal is a service $25, twenty minutes, dissolved off, and free when you book a new set the same visit. Any salon's work. If one extension is driving you mad, that appointment exists so you do not solve it yourself at midnight.

If you had brows done too

Brow lamination aftercare is a shorter list.


Keep them completely dry for 24 hours — no water, no steam, no sweating, no makeup on or near the brow, and do not touch them. After that, brush them into shape each morning and use the nourishing oil a few times a week. And do not re-laminate more often than every six weeks; over-processing is real.

Questions

Aftercare, answered.


How do you clean lash extensions?

Daily, at night, with a dedicated lash shampoo. A pump on a clean fingertip or the brush, worked gently side to side along the lash line with the eye closed, rinsed with lukewarm water until no foam is left, patted dry, then brushed through with the spoolie once dry. Ninety seconds. Every new client goes home with the shampoo and brush.

Do lash extensions ruin your natural lashes?

Not when they are properly weighted, applied with each natural lash isolated, and dissolved off rather than pulled. Damage has three causes: extensions heavier than the lash can carry, two natural lashes bonded together so one pulls the other out early, and sets being pulled off at home. All three are avoidable, which is why mapping happens first and removal is a $25 service rather than something you do yourself.

How long do lash extensions last?

Individual extensions last as long as the natural lash they are attached to, which is a six-to-eight-week growth cycle — but lashes shed on staggered schedules, so you lose a few every day. In practice the set reads uneven at two weeks and patchy at three, which is the refill window. No adhesive, serum or aftercare routine extends a set beyond your own shed cycle; aftercare decides how even the loss looks.

Can I wear makeup with lash extensions?

Yes, with two exceptions. No waterproof mascara — removing it means rubbing the lash line with solvent and that takes extensions with it. And nothing oil-based within an inch of the lashes, which rules out most cleansing balms, oil makeup removers and some rich eye creams. Water-based eyeliner and shadow are fine; just clean them off properly at night.

Why are my lash extensions falling out so fast?

In order of likelihood: oil-based products at the lash line, sleeping face-down, touching or picking at them, and not cleaning them at all. Beyond habits, shed rate is seasonal — most people lose more in spring and autumn — and pregnancy or a change in medication can change retention noticeably. If nothing in your routine changed, that is usually the explanation.

Can I use a lash serum with extensions?

A conditioning serum applied to the lash line, not the extensions, is fine and keeps the natural lash flexible. Avoid anything oil-based and avoid applying it along the extensions themselves. No serum regrows a follicle that is gone, whatever the packaging says.

Can I go to the gym or swim with lash extensions?

Yes, from day two with standard adhesive and from the same day with the LED-cured bond. Rinse with fresh water after chlorine or salt water, let them dry, then brush them. Chlorine does not dissolve the bond; what causes problems is leaving salt or chlorine residue sitting at the lash line for days.

How should I sleep with lash extensions?

On your back if you can, and on a silk or satin pillowcase. Face-down sleeping is one of the biggest causes of early loss — extensions get crushed and twisted against the pillow for seven hours, and twisted lashes come out before their time. Side sleeping is a compromise: alternate sides, and expect the side you favour to look thinner by week two. This single habit does more for retention than any product you can buy.

Can I use a sauna or steam room with lash extensions?

Yes, after the first 24 hours — or the same day if you added the LED-cured bond. Heat and steam do not dissolve a cured bond. What they do is soften makeup and sebum at the lash line, so rinse with fresh water afterwards, let them dry, then brush them through. Repeated long sessions at high heat and humidity will shorten retention a little, so if you are in a steam room daily, expect to refill at two weeks rather than three.

Can I wear glasses with lash extensions?

Yes, and it is worth mentioning at the mapping stage rather than afterwards. If your frames sit close to your face, long extensions through the centre of the eye will brush the lens — which is annoying rather than harmful, but it smudges the glasses and bends the lashes. The fix is a slightly shorter length through the middle zone, or a flatter curl. Tell us you wear glasses and we map around them.

Can I put castor oil or coconut oil on lash extensions?

No. Oil is what dissolves the bond — it is the same mechanism that makes oil-based cleansers the main cause of bad retention. Castor oil on extensions will slide them off, usually unevenly, and you will be back for a refill early. If you want to use castor oil to condition your natural lashes, do it during a break from extensions, not while you are wearing a set. A conditioning serum applied to the lash line rather than along the extensions is the version that works alongside a set.
