The Investment & Health Imperative: Why you must clean your lashes
Thinking of a lash cleanser as just another soap is like thinking of a toothbrush as an optional extra. It's not a luxury; it's an absolute necessity for two critical reasons: it protects your financial investment and it fulfills a vital health imperative.
Protect your investment: Better retention means less money on infills
Let’s talk numbers. A full set of volume lashes can cost upwards of $150, with infills every two to three weeks running around $80–$100. Meanwhile, a high-quality lash cleanser concentrate typically costs around $25 and can last for several months.
By incorporating a daily lash cleansing routine, you significantly improve lash retention. This allows you to extend your infill appointments from every two weeks to every three or even four weeks. Adding just one extra week to your infill cycle can save over $600 per year. That little bottle of lash cleanser isn’t an expense - it’s a smart beauty investment. [1]

Prevent eye infections: The unseen dangers on your lash line
Your lash line is a delicate ecosystem. Failing to clean it properly allows makeup residue, dead skin cells, dirt, and natural oils to build up. This sticky film becomes the perfect breeding ground for bacteria, which can lead to unpleasant eye conditions.
The most common issue is blepharitis, an inflammation of the eyelids that causes redness, itching, crusting, and a gritty sensation. It’s far more widespread than you might expect—one 2019 study in Australia and New Zealand reported that 47% of patients presenting to clinics had blepharitis [2]. Daily cleansing with a specially formulated lash cleanser for eyelash extensions is your strongest defense against this uncomfortable and persistent condition.
The "Ick" factor: Say goodbye to Lash Mites (Demodex)
Here’s a truth that might make you want to wash your lashes right away: microscopic mites live on our skin, including our eyelashes. Known as Demodex, they are harmless in small numbers.
These mites feed on oils and dead skin cells that accumulate along your lash line. Without regular cleansing, you essentially provide a buffet for them, which can lead to overpopulation and the same inflammation and irritation associated with blepharitis. A daily wash with a quality lash cleanser concentrate removes their food source, keeping both the population in check and your lash follicles healthy and clean.
Maintain fluffy, beautiful fans
If you’ve invested in lush, fluffy volume or mega volume fans, the last thing you want is clumpy, spidery lashes. Oils, makeup residues, and daily grime act like glue, sticking the delicate fibres of your fans together.
This completely ruins the soft, lightweight look you paid for. A gentle, foaming lash cleanser for eyelash extensions works to dissolve buildup without harming the adhesive, allowing you to brush your extensions back into their original, perfectly fanned-out state. It’s the difference between lashes that look stunning for one week versus three weeks.
The importance of cleaning your lashes
What to look for in a lash cleanser
Not all cleansers are created equal. Using the wrong product can be just as harmful as not cleaning your lashes at all. Here’s what makes a lash cleanser for eyelash extensions both safe and effective.
The golden rule: It must be oil-free
This is the single most important rule. The adhesive used to bond extensions to your natural lashes is cyanoacrylate, and its mortal enemy is oil. Oil can seep into the adhesive bond and break it down from the inside, causing your extensions to slide off prematurely. A quality lash cleanser concentrate must be 100% oil-free. Always check labels carefully, as oils can hide in many common facial cleansers and makeup removers.
PH balanced for eye safety
Natural tears have a pH level of approximately 7.0. Any product that is significantly acidic or alkaline can cause stinging or irritation to the eyes. A professional lash cleanser for eyelash extensions is carefully pH-balanced to be as gentle as possible on the delicate eye area. This is a key feature that sets a high-quality lash cleanser apart from a generic face wash - or worse, baby shampoo.
Key Cleansing & Soothing Ingredients
Look for formulas that do more than just clean. The best lash cleanser concentrates contain ingredients that care for both the skin and your natural lashes.
Expert Quote: "An effective lash cleanser relies on gentle surfactants like Sodium Cocoyl Glycinate, which create a soft foam to lift away debris without stripping the skin," notes cosmetic chemist Gabriella Russo. "We also look to include botanical extracts, such as Tea Tree for its natural antibacterial properties or Aloe Vera to soothe the eyelid, creating a product that is both effective and nurturing."
Professional Grade vs. Drugstore Brands
While it may be tempting to pick up a generic foaming cleanser from a local chemist, these products are not specifically formulated for use with eyelash extensions. They may contain hidden oils, alcohols, or glycols that aren’t listed on the front label, which can damage the lash adhesive. A professional-grade lash cleanser for eyelash extensions is specifically created and tested to clean your extensions safely and prolong their lifespan.
At Lashes by RK, we’re committed to providing the best care for your clients’ lashes. Our foam lash extension cleansers and lash shampoo concentrate are perfect for gentle yet effective cleaning.

What you'll need
- Lashes by RK Foaming Lash Cleanser
-
A soft-bristle lash cleansing brush
- A clean, fluffy mascara wand (spoolie)
- Lukewarm water
The 5-Step Cleansing Method
-
Wet your eyes. Start by gently splashing your eye area with lukewarm water. Avoid using hot water, as it can affect the adhesive bond over time.
-
Apply cleanser. Dispense one pump of lash cleanser concentrate onto the back of your clean hand or directly onto the tip of your damp brush. A small amount is enough to create a soft foam.
-
Gently cleanse. Close one eye and use the brush to gently work the foam into your lash line. Use soft, downward strokes from the base of the eyelid to the tips of the extensions. Don't be afraid to clean the area where the extensions are bonded. That's where the buildup happens!
-
Rinse thoroughly. Rinse all the cleanser away with lukewarm water, ensuring no residue remains.
-
Dry and fluff. Gently pat the area dry with a soft, lint-free towel or let it air dry. Once completely dry, use a clean spoolie to gently brush through your extensions, fanning them back into perfect shape.
Advanced cleaning techniques
For classic & hybrid lashes
With classic lash extensions & hybrid lashes, ensure the brush is positioned directly at the base of each lash. Use small, circular motions right at the lash line before stroking downwards to the tips.
For volume & mega volume fans
To protect the delicate structure of volume fans, avoid vigorous side-to-side scrubbing. Instead, use a gentle "patting" or "stippling" motion with your brush. This pushes the foam through the fans to clean them without clogging them up. Brushing them with a spoolie after they are fully dry is the key to restoring that signature fluffiness.

Lash aftercare myths: What NOT to use on your extensions
There’s a lot of confusing advice online. Using the wrong product on your extensions can cause damage and reduce their lifespan.
Myth 1: Baby Shampoo
This is one of the most persistent and damaging myths in the lash world. Despite being labeled “tear-free,” baby shampoo is not suitable for use on extensions. It’s alkaline (not pH-balanced for eyes), often contains oils to moisturise a baby’s scalp, and leaves behind a soapy residue that suffocates the adhesive bond, preventing it from curing properly. Always choose a professional lash cleanser for eyelash extensions or a safe lash cleanser concentrate instead.
Myth 2: Micellar Water, Wipes, or Other Cleansers
Micellar water and makeup wipes are formulated to remove makeup, often using oils or glycols to do so. These ingredients are harmful to the lash adhesive. Unless a product explicitly states it is 100% oil-free and safe for extensions, assume it is unsuitable. Always check the full ingredient list and use a lash cleanser for eyelash extensions specifically designed for safe daily use.
Myth 3: Not Washing Them At All
Some people avoid washing their lashes out of fear they’ll fall out. The opposite is true. Clean lashes are healthy lashes. It’s the buildup of oils, dirt, and debris that breaks down the adhesive, causing premature shedding. Naturally, you lose 2–5 lashes per eye each day as part of your lash growth cycle [3]. This is normal shedding, not damage from cleaning. For stronger, healthier lashes, incorporate a gentle lash cleanser into your daily routine. Commit to clean lashes for the best environment for new lash growth.

Lash Cleanser FAQs: Your Questions Answered
1. How often should I be cleaning my lash extensions?
You should be cleaning them daily. The best time is at night, as part of your skincare routine. This removes all of the day's makeup, pollutants, and skin oils before you go to sleep.
2. Why do my eyes burn when I wash my lashes?
This could be due to a few reasons: the cleanser isn't pH-balanced for the eyes, you're accidentally getting foam directly inside your eye, or you may have a pre-existing sensitivity. A professional, gentle formula like the Lashes by RK cleanser is specifically designed to minimise stinging and irritation.
3. Can I use a lash cleanser right before my infill appointment?
Absolutely! In fact, we highly recommend it. Arriving at your appointment with perfectly clean lashes is a lash artist's dream. It means they can get straight to work applying new lashes, ensuring the strongest possible bond and giving you a longer-lasting infill.
4. What can I use if I run out of my lash cleanser?
In an absolute pinch, cleaning your extensions with just lukewarm water is better than not cleaning them at all. However, water alone cannot effectively break down and remove oil buildup. You should order a replacement cleanser immediately to keep your lashes in optimal condition.
5. Can I use micellar water as a lash lift cleanser?
No, micellar water isn’t the ideal or recommended cleanser for a lash lift. For best results, use a gentle, oil-free lash cleanser specifically formulated for lash care and treatment. Micellar water doesn’t provide enough lather or cleansing power to fully remove dirt and buildup along the lash line, which can lead to poor retention or even lash breakage.
6. Is the Lashes by RK cleanser vegan and made in Australia?
Yes! We are incredibly proud that our cleanser is 100% vegan, cruelty-free, and Australian-owned and operated. The formula is designed by lash experts for our local clients and standards.
The Takeaway: Make Lash Cleanser Your #1 Aftercare Priority
Your eyelash extensions are a beautiful investment in yourself. The single most effective way to protect that investment, safeguard your eye health, and enjoy your lashes for as long as possible is to commit to a daily cleansing routine.
By removing the daily buildup of oils, makeup, and debris, you ensure a stronger adhesive bond, prevent infections like blepharitis, and keep your extensions looking as fluffy and flawless as the day you got them. It’s the one step that delivers unbeatable results.
