Getting lash extensions is the easy part. The appointment is relaxing, the results are immediate, and you leave the salon wondering why you didn’t do this sooner. What happens in the 24 to 48 hours after your appointment — and in the weeks that follow — is what determines whether your lashes last two weeks or five.
At Ma Dame Salon in Hicksville, every lash client leaves with a clear understanding of exactly what to do and what to avoid. This post covers all of it in detail so you have it as a reference from the moment you walk out the door.
The First 24 to 48 Hours: The Window That Matters Most
Lash adhesive requires time to fully cure after application. During the curing period — typically 24 to 48 hours depending on the adhesive formula and the ambient humidity — the bond between the extension and your natural lash is at its most vulnerable. What you do during this window has a disproportionate impact on how well your lashes hold through the first week and beyond.
Keep your lashes completely dry for the first 24 hours.
No water on the face, no steam, no sweating heavily. This means no washing your face with running water near the eye area, no hot showers where steam accumulates, no workouts that produce significant sweat, and no swimming. After 24 hours — 48 is safer if you want maximum hold — normal water exposure resumes with some ongoing precautions.
Avoid heat sources near your face.
Opening a hot oven, leaning over steam from a pot, or sitting too close to a fireplace or candle during the curing window can soften the adhesive before it fully sets. It’s a less obvious precaution than keeping lashes dry, but it matters for the same reason.
Do not touch, rub, or pull your lashes.
The impulse to touch new lashes is understandable — they feel different and you want to see how they look. Resist it completely during the first 48 hours. Any mechanical pressure on the lashes during curing disrupts the bond. Rubbing is the single fastest way to lose lashes prematurely regardless of when it happens, but it’s especially damaging in those first two days.
Sleep on your back or side — not your face.
Face-down sleeping creates sustained pressure and friction on the lashes throughout the night. A silk pillowcase reduces friction significantly for side sleepers. If you’re a dedicated stomach sleeper, a lash-friendly sleep mask or simply being conscious of your position for the first couple of nights makes a real difference.
The Ongoing Cleaning Routine: The Step Most Clients Skip
Here’s the aftercare mistake that causes more lash problems than almost anything else: not cleaning lash extensions because clients are afraid cleaning them will remove them.
Unwashed lash extensions accumulate oil, dead skin cells, makeup residue, and bacteria at the lash line. That buildup breaks down the adhesive bond over time — meaning dirty lashes actually fall out faster than clean ones. It also creates a genuine eye health risk. Cleaning your lashes properly and regularly is not optional; it’s one of the most important things you can do to maintain your set.
How to clean lash extensions correctly:
Use a dedicated oil-free lash cleanser — not your regular facial cleanser, not micellar water, not makeup remover wipes. Many everyday cleansing products contain oils or alcohol that degrade lash adhesive, even products that seem gentle.
Apply the cleanser to a clean, soft brush — a dedicated lash cleansing brush or a very soft makeup brush — and work it through the lashes gently in a downward direction. Don’t rub sideways or scrub. Rinse with cool water and pat — never rub — dry with a clean lint-free cloth or tissue.
Clean your lashes at minimum every two to three days, or daily if you wear eye makeup regularly. At Ma Dame Salon we recommend building lash cleansing into your nightly skincare routine so it becomes automatic rather than something you remember to do occasionally.
Brush your lashes daily.
A clean spoolie brushed through your lashes once in the morning — starting from the mid-shaft and sweeping outward toward the tips — keeps them aligned and prevents tangling. Never brush from the root, and never brush wet lashes. Wait until they’ve air-dried after cleansing before brushing.
Products to Avoid Around Lash Extensions
Oil is the primary enemy of lash adhesive. It breaks down the bond gradually but reliably, regardless of how well everything else in your aftercare routine is going. The products most commonly causing problems for lash extension clients at Ma Dame Salon are ones clients didn’t realize contained oil.
Avoid oil-based products anywhere near the eye area:
- Oil-based makeup removers and cleansing balms
- Most standard moisturizers and eye creams — check ingredient lists for anything ending in “-oil,” “butter,” or “glycerin” high on the list
- Waterproof mascara — removing it requires oil-based remover, which then contacts the adhesive
- Oil-based foundations or concealers applied near the lower lash line
Avoid waterproof eye makeup entirely.
Regular mascara on extensions isn’t recommended in any case — the extensions already provide the volume and definition mascara would add, and mascara is difficult to remove without disrupting the set. Waterproof formulas are worse because the removal process requires oil-based products. If you want to wear eyeliner, use an oil-free, water-based formula and apply it carefully along the upper lash line rather than on or between the extensions.
Avoid steam rooms, saunas, and prolonged hot showers.
Steam doesn’t just affect the curing window — ongoing exposure to heat and steam weakens adhesive bonds over the full life of your set. Keeping shower temperature moderate and keeping your face out of the direct steam stream during showers makes a meaningful difference in how long your lashes hold.
The Fill Schedule: When to Come Back
Lash extensions shed naturally with your lash cycle — most people lose somewhere between 2 and 5 natural lashes per day as part of normal growth and renewal. Each shed natural lash takes its extension with it, which is why a full set gradually thins over time regardless of how well you follow aftercare.
Most clients at Ma Dame Salon schedule fills every two to three weeks. At the two-week mark, a set typically has lost enough extensions to look noticeably thinner but still has enough base to fill efficiently. Waiting longer than three weeks often means the remaining extensions are too sparse to fill effectively, which can push the appointment into new set territory in terms of time and cost.
Signs it’s time for a fill:
- Visible gaps in your lash line when you look straight into a mirror
- Extensions that feel noticeably lighter or less full than when you left the salon
- Individual extensions that have grown out significantly from the natural lash line
The two-to-three week fill schedule is also what keeps your lashes looking consistently full rather than cycling between full and sparse. Clients who book their next fill appointment before they leave the salon maintain a more consistent result than those who book reactively when their lashes have already thinned significantly.
Common Mistakes That Shorten Lash Life
After working with lash clients across Hicksville and Long Island, the mistakes that come up most consistently are:
Not cleaning regularly. The most common and most impactful mistake, covered above.
Rubbing eyes. Habitual eye rubbing is the fastest route to early lash loss. If you wake up rubbing your eyes, sleeping with a silk eye mask creates a physical barrier that reduces both rubbing and friction.
Using cotton products near the lashes. Cotton pads, cotton balls, and cotton swabs shed fibers that catch on extensions and cause snagging. Switch to lint-free applicators for everything near your eyes.
Picking at grown-out extensions. When extensions grow out with the natural lash, the temptation to pick them off is real. Don’t. Picking extensions off removes the natural lash they’re attached to, causing gaps that take the full lash growth cycle — 6 to 8 weeks — to fill back in. Come in for a professional removal if needed.

FAQ SECTION
Q: Can I get my lash extensions wet after 24 hours in Hicksville’s humidity?
A: After the initial 24 to 48 hour curing window, water exposure is fine — but how you manage that exposure matters. Avoid prolonged steam, keep shower temperature moderate, and never rub your lashes when they’re wet. Pat them dry gently with a lint-free cloth and let them air-dry fully before brushing. Long Island humidity itself doesn’t significantly affect lash hold after the curing period, but steam from hot showers and saunas does weaken adhesive bonds over time.
Q: How do I clean lash extensions without removing them?
A: Use an oil-free lash extension cleanser applied with a soft dedicated brush, working gently downward through the lashes. Rinse with cool water and pat dry — never rub. Avoid any cleanser containing oil, alcohol, or glycerin high on the ingredient list. Cleaning lashes properly actually helps them last longer by removing the oil and debris buildup that degrades adhesive bonds over time. Clean lashes hold better than dirty ones.
Q: How often should I get lash fills at Ma Dame Salon in Hicksville?
A: Most clients at Ma Dame Salon schedule fills every two to three weeks. At the two-week mark, a set has typically thinned enough to look noticeably less full but retains enough base for an efficient fill. Waiting beyond three weeks often means the remaining extensions are too sparse to fill without approaching the time and cost of a new full set. Booking your next fill before you leave the salon is the easiest way to maintain consistent results.
Q: Why are my lash extensions falling out faster than expected?
A: The most common causes of premature lash shedding are oil-based products near the eye area breaking down the adhesive, not cleaning the lash line regularly enough allowing buildup to degrade the bond, rubbing or touching the lashes habitually, and prolonged steam exposure from hot showers or saunas. If your lashes are consistently shedding faster than two weeks, mention it at your next Ma Dame Salon appointment and we’ll assess your aftercare routine and adhesive compatibility together.
Q: Can I wear mascara on my lash extensions from Ma Dame Salon?
A: Mascara on extensions is not recommended — the extensions already provide the volume, length, and definition mascara would add, and mascara is difficult to remove without oil-based products that degrade lash adhesive. If you want additional definition, a water-based, oil-free eyeliner applied carefully above the lash line is a better option. Waterproof mascara and waterproof eyeliner should both be avoided entirely, as their removal requires oil-based products.
