The lash artist who gave you your set spent 2 hours making them look perfect. Whether they still look perfect two weeks from now is almost entirely up to you.
Aftercare matters more than any other single factor in how your lash extensions perform. It matters more than which curl your artist chose, more than the brand of adhesive she used, more than the price you paid. Two clients who leave the exact same appointment with the exact same set can look completely different at their two-week infill — one still full and clean, one thin, tangled, and half-shed. The difference is aftercare.
This is the complete aftercare guide every Australian lash client should have. The first 24 hours, the daily and weekly rules, the products that actually help, the mistakes to avoid, and how aftercare changes depending on your lifestyle. Written from years of doing lash work in Perth and — importantly — seeing what happens when clients follow the rules versus when they don't.
The First 24–48 Hours — the Critical Window
Lash adhesive cures over 24–48 hours after application. During that window, the bond between your extension and natural lash is forming its full strength. Anything that interferes with this curing process reduces how long your set will last.
For the first 24–48 hours after your appointment:
- No water on the lashes. No shower spray on the face, no pool, no beach, no sweaty workout, no crying if avoidable.
- No steam or heat. No sauna, no steam room, no cooking over hot pots, no hair drying pointed at the face.
- No makeup on the eyes. Eyeshadow, eyeliner, and concealer around the eye can transfer to the lash line before the bond is fully set.
- No touching or rubbing. Not even to check how they feel.
- Sleep on your back. Face-down sleep during the curing window will bend the extensions permanently.
After the 48-hour mark, you can return to normal activities — but the daily and weekly rules that follow apply for the entire life of the set.
Daily Aftercare — the 3-Minute Morning Routine
The daily aftercare rhythm is faster than people expect. Total time investment: about 3 minutes each morning.
1. Brush with a clean spoolie
Every morning, brush your lashes with a clean spoolie brush. This realigns extensions that shifted during sleep, prevents crossovers, and evenly distributes any natural oils. Brush upward from base to tip, gently. Never brush wet lashes — always dry.
A clean spoolie is essential. Rinsing yesterday's spoolie under warm water for 5 seconds is enough. Never use one that has visible product buildup.
2. Cleanse the lash line (every 1–2 days)
Cleaning the lash line with a foaming lash cleanser removes oil, sweat, makeup residue, and dust that accumulate at the bond point. Skipping this step is the single biggest reason retention drops after week 2.
Foam the cleanser between your palms first, then apply gently to the lash line with a soft brush or your clean fingertip. Rinse with cool water. Pat dry with a lint-free cloth. Don't rub.

3. Air-dry, then brush again
Once your lash line is dry (2–3 minutes), give the lashes a final brush. This restores the fanned shape after cleansing.
Weekly Aftercare Rules
The weekly rules are shorter than the daily list but non-negotiable:
- Cleanser check. Once a week, replace your foaming pump top if you've had it more than 8 weeks. Cleansers oxidise over time and become less effective.
- Pillowcase change. Weekly wash of your pillowcase, or every 3–4 days for oily skin. Silk pillowcases extend the interval between washes and reduce friction damage.
- Product audit. Check the ingredient list of any new eye cream, moisturiser, or makeup you've added — oils and heavy silicones can migrate to the lash line.
- Spoolie replacement. Replace your spoolie every 4–6 weeks. Bristles bend over time and stop working properly.
Monthly Aftercare — Infill Schedule
Extensions shed at the same rate as your natural lashes — approximately 20–30% per week. To keep the set looking full, book infill appointments every 2–3 weeks. Waiting longer than 4 weeks between infills usually means your artist has to do a partial re-set rather than a fill.
| Weeks since last set | What your lashes look like | Recommended action |
|---|---|---|
| 1 week | 85–95% full | No action needed |
| 2 weeks | 65–75% full | Book infill now for a consistent look |
| 3 weeks | 45–55% full | Infill or full reset depending on artist |
| 4 weeks | 20–35% full | Full re-set recommended |
| 5+ weeks | Sparse patches, may look unbalanced | Full reset only |
The Best Products for Lash Aftercare
You need surprisingly few products for good aftercare — but the ones you do need have to be the right ones. Here's the complete kit:
Foaming lash shampoo (essential)
Oil-free, sulfate-free, purpose-formulated for lash extensions. Avoid generic face cleansers, baby shampoo, and micellar water — none are designed for extension safety. See our full lash shampoo guide for the picks we recommend at Posh Deluxe.
Clean spoolie brushes (essential)
Buy a pack of disposable spoolies — you'll get through them faster than you think. Available at poshdeluxe.com.au/collections/aftercare.
Lash cleansing brush (recommended)
A soft-bristle brush designed for foaming cleanser application to the lash line. Sits at your bathroom sink and takes cleansing time from a minute to 20 seconds.
Silk pillowcase (recommended)
Reduces friction between your face and pillow while you sleep. Extends set lifespan noticeably — most clients notice better retention within the first cycle after switching.
Lash sleep mask (optional)
A domed sleep mask that holds off the lashes rather than pressing on them. Especially useful for face-down sleepers.
Oil-free eye makeup remover (essential if you wear eye makeup)
Read every ingredient list — anything with mineral oil, coconut oil, argan oil, or "oil" anywhere near the top of the list will shorten your set. Water-based, oil-free formulations only.
The 10 Aftercare Mistakes to Avoid
Every damaged or prematurely-shed set traces back to one of these ten mistakes. Avoid all ten and your set will last its full cycle:
- Skipping the daily cleanse. The single biggest retention killer.
- Using oil-based makeup or skincare. Cyanoacrylate adhesive dissolves in oil.
- Rubbing or touching your eyes. Breaks the bond every time.
- Sleeping face-down. Bends and breaks extensions.
- Using mascara. Even "lash-safe" mascara clumps extensions.
- Trying to remove lashes yourself. Takes natural lashes with them.
- Overdue infills. Grown-out extensions stress the natural lash root.
- Water hitting the lashes at high pressure. Hot direct shower spray weakens the bond faster than gentle water contact.
- Steam exposure. Sauna, steam room, and hot yoga are the top three culprits.
- Assuming your natural growth cycle is a "product problem." Some shedding is normal. See our 15 Common Lash Retention Killers post for the full retention framework.
Aftercare by Activity — Real Life with Lash Extensions
The rules above apply universally, but each daily activity has its own considerations:
Showering
Fine after 48 hours. Face away from direct water spray, keep the water lukewarm rather than hot, and don't let shampoo or conditioner run down onto the lash line. Rinse the lash line clean after showering if products touched them.
Swimming (pool)
Fine, but rinse lashes with fresh water immediately after leaving the pool. Chlorine breaks down adhesive if left on the lash line for extended periods.
Swimming (ocean)
Fine with the same rule — rinse in fresh water immediately after. Saltwater is gentler than chlorine but still needs to be rinsed off.
Gym workouts
No restriction. Sweat is water-based and won't damage the bond. Pat dry the lash line after intense workouts, and cleanse in the evening.
Sauna and steam room
These are the two hardest environments for extensions. Occasional use is fine; multiple weekly visits will shorten your set noticeably. Consider spacing sauna sessions between infill dates rather than immediately after new sets.
Beach days
Fine with sunscreen caution — apply sunscreen carefully around the eye area and avoid getting it on the lash line. Rinse lashes in fresh water at the end of the day.
Long-haul flights
Cabin air is drying but not damaging. Bring a spoolie in your carry-on for post-landing realignment. Skip the eye mask that presses directly on the lashes — use a domed lash-safe sleep mask instead.
Hot yoga
Same as sauna — occasional is fine, several times a week will shorten your set. If you're a regular hot yoga practitioner, tell your artist so she can choose an adhesive that suits.
Crying
Blot tears with a tissue rather than wiping. If you've had a big cry, rinse the lash line with fresh water afterward.
Aftercare for Sensitive Eyes
Clients with sensitive eyes need a few adjustments to standard aftercare:
- Use lukewarm rather than cold water when cleansing.
- Choose a fragrance-free lash cleanser — many "gentle" cleansers still contain essential oils that irritate.
- Rinse cleanser off with more water than you think you need. Any residue can irritate.
- Never let cleanser sit on closed eyes for extended periods.
- If your eyes feel gritty or itchy the day after a new set, book a check-in with your artist rather than rubbing.

Signs Your Aftercare Is Working (or Not)
You can tell within the first 10–14 days whether your aftercare is on track:
| Sign | Aftercare is working | Aftercare needs adjustment |
|---|---|---|
| Lashes at day 10 | Still 70–80% full, aligned, clean bases | Sparse, tangled, visible residue at bases |
| Comfort | Feel like nothing is there | Itchy, gritty, or tight-feeling |
| Bond point | Clean, thin adhesive dot | Yellow buildup, oily residue, white blooming |
| Natural lashes | Same as before extensions | Feel thinner or shorter |
| Shedding pattern | Even, gradual, matches growth cycle | Sudden clumps, uneven patches |
| Infill appointment length | Standard 45–60 min | Artist needs 90+ min because half the set has shed early |
Frequently Asked Questions
How soon after getting lash extensions can I shower?
Wait 24–48 hours before showering. When you do, keep water pressure low, temperature lukewarm, and face out of direct spray.
Can I sleep on my side with lash extensions?
Yes — side sleeping is fine after the 48-hour curing window. Only face-down sleeping needs to be avoided. A silk pillowcase and a lash sleep mask both help extend the set for side-sleepers.
Do I need to wash my lash extensions every day?
Every 1–2 days is standard. Daily is fine if you wear eye makeup, work out heavily, or have oily skin. Every 2–3 days is the minimum acceptable frequency.
Can I use micellar water on lash extensions?
No — micellar water contains surfactants that can weaken the adhesive bond. Use a purpose-made foaming lash cleanser instead.
Will hairspray damage my lash extensions?
Direct hairspray on the lash line can. Shield your eyes with your hand when spraying, or apply hairspray before doing your lash line cleanse for the day.
Can I get lash extensions wet in the first 24 hours?
No — this is the single most important restriction. The bond is still curing during the first 24–48 hours.
How often should I get infills?
Every 2–3 weeks is standard. Waiting longer than 4 weeks typically means a full re-set is needed rather than a fill.
What happens if I skip a lash cleanse for a few days?
Bacteria, oil, and dust build up at the lash line — this weakens retention and can cause lash mites in extreme cases. A few missed cleanses won't destroy the set, but they will shorten it.
The Bottom Line
Lash extension aftercare is simple but non-negotiable. The daily 3-minute routine — brush, cleanse, brush again — plus the weekly and monthly rules is all it takes to get every dollar of value from your set. Skip it and you'll be paying for a new full set 30% more often than you need to.
The single most important habit is the daily foaming cleanse. If you take only one thing from this guide, take that. Every other rule matters, but that one matters most.
Get the routine right and your extensions will look as good at your infill as they did the day you left the salon. Every artist wants their clients back for infills, not for damage rescues — and every client wants the same. Aftercare is where those two goals meet.
