If your DIY lashes aren’t lasting as long as expected, don’t worry. In most cases, the issue can be resolved with a few simple adjustments to your application technique. Below are the most common reasons your lashes may not be staying on, along with tips to help you achieve longer-lasting wear.

1. Your natural lashes weren’t completely clean

Before applying your Sirenn Lashes, your natural lashes should be completely free from oil, makeup, mascara, skincare products, and dirt. Even a small amount of residue can prevent the adhesive from bonding properly.

Solution: Wash your lashes thoroughly and ensure they’re completely dry before applying your lashes.

2. You applied too much or too little Sirenn Lash Glue

Using too much glue can prevent it from curing properly, while too little may not create a strong enough bond.

Solution: Apply a thin, even layer of Sirenn Lash Glue to the base of your natural lashes. Less is often more.

3. You didn’t wait for the glue to become tacky

Applying your lash segments immediately after applying the glue can reduce its effectiveness.

Solution: Wait approximately 30 seconds for the glue to become tacky before applying your first lash segment.

4. Your lash segments were applied too close to your waterline

Applying your DIY lashes directly against your waterline can cause discomfort and make the lash segments lift more easily.

Solution: Apply each lash segment approximately 1-2 mm away from your waterline, ensuring your natural lash roots remain visible.

5. You skipped Sirenn Lash Seal

Lash Seal is an essential step that helps lock in the adhesive, reduce stickiness, improve water resistance, and maximise wear time.

Solution: Always finish your application with Sirenn Lash Seal. For even better results, apply a small amount of Lash Seal to your applicator before clamping your lashes together to help seal both the top and bottom of the lash band.

6. You didn’t clamp your lashes properly

Clamping helps fuse your natural lashes and the lash segments together, creating a stronger bond.

Solution: Gently clamp your lashes after application, then clamp them once more after applying Lash Seal.

7. Your lashes got wet too soon

The adhesive needs time to fully cure after application.

Solution: Avoid getting your lashes wet for the first 6-8 hours after application.

8. Oil-based products are breaking down the adhesive

Oil is one of the biggest reasons DIY lashes lose their hold prematurely.

Solution: Avoid oil-based cleansers, makeup removers, eye creams, and skincare products around the eye area while wearing your lashes.

9. Your application method may not be the best match for you

Everyone’s natural lashes, skin type, lifestyle, and application technique are different. Some customers achieve longer wear with Sirenn Lash Glue, while others find InstaGlue Tabs work much better for them.

Solution: If you’ve followed all the recommended application steps and still aren’t getting the longevity you’d hoped for, we recommend trying the other application method. Many customers discover that switching from Lash Glue to InstaGlue Tabs, or vice versa, dramatically improves their results.

If your DIY lash clusters are lifting at the inner or outer corners, don’t worry. This is one of the most common issues beginners experience and is usually caused by a few simple application mistakes. The good news is that it’s easy to fix.

1. Your lash segments are too close to your waterline

Applying your lash clusters directly against your waterline can cause them to lift as your eyes naturally produce moisture throughout the day.

Solution: Apply each lash segment approximately 1-2 mm away from your waterline, ensuring your natural lash roots remain visible.

⸻

2. You’re not overlapping the lash segments

If there is a gap between your lash clusters, they won’t support each other and are more likely to lift.

Solution: Slightly overlap each lash segment by 1-2 mm to create one continuous lash line and improve durability.

⸻

3. The ends of the lash band aren’t fully secured

Sometimes the very first or last lash segment isn’t pressed firmly enough into place, causing the corners to lift first.

Solution: Take a few extra seconds to gently press the inner and outer lash segments into place before clamping.

⸻

4. You didn’t clamp your lashes after application

Clamping helps fuse your natural lashes and the lash clusters together, creating a stronger, longer-lasting bond.

Solution: Gently clamp your lashes once after application, then apply Sirenn Lash Seal. For the best hold, apply a small amount of Lash Seal to your applicator before clamping again. This helps seal the lashes from both the top and bottom while reducing the chance of accidentally pulling the lash segments off during clamping.

5. You skipped Sirenn Lash Seal

Lash Seal is an important step that helps lock in the adhesive, improve water resistance, and maximise wear time.

Solution: Always finish your application with Sirenn Lash Seal.

6. Oil or makeup has weakened the adhesive

Oil-based skincare, cleansers, makeup removers, or leftover makeup can break down the adhesive and cause the lash clusters to lift prematurely.

Solution: Ensure your natural lashes are completely clean before application and avoid oil-based products around the eye area while wearing your lashes.

⸻

7. Leave a few natural lashes free on the outer corner

Depending on your eye shape, applying a lash segment all the way to the very outer corner can create tension as your eyes move throughout the day, causing the outer corner to lift.

Solution: Try leaving the last 2 to 3 natural lashes on your outer corner without a lash segment. This reduces tension on the outer corner, creates a more comfortable fit, and can significantly improve retention while still giving you a seamless, full lash look.

⸻

8. Your application method may not be the best match for you

Every person’s natural lashes, skin type, and lifestyle are different. Some customers experience better retention with Sirenn Lash Glue, while others achieve longer-lasting wear with InstaGlue Tabs.

Solution: If you’ve tried all the steps above and your lash clusters are still lifting, we recommend trying the other application method. Many customers find that switching from Sirenn Lash Glue to InstaGlue Tabs, or vice versa, gives them significantly better results.

If your DIY lashes feel sticky after application, don’t worry. This is completely normal and is usually caused by adhesive that hasn’t been properly sealed. The good news is that it’s quick and easy to fix.

1. You haven’t applied enough Sirenn Lash Seal
Whether you’ve applied your lashes using Sirenn Lash Glue or InstaGlue Tabs, Sirenn Lash Seal is an essential final step. Without enough Lash Seal, the adhesive can remain tacky and cause your lashes to feel sticky.
Solution: Apply Sirenn Lash Seal along the lash line to remove the sticky feeling, lock in the adhesive, improve water resistance, and maximise wear time. If your lashes still feel sticky, apply a second light layer of Lash Seal.

2. You applied too much Sirenn Lash Glue
If you’re using Sirenn Lash Glue, applying more glue than necessary can leave excess adhesive exposed, making your lashes feel sticky.
Solution: Apply a thin, even layer of Sirenn Lash Glue to the base of your natural lashes. A small amount is all you need.

3. The adhesive hasn’t fully cured yet
Your adhesive needs a few minutes to fully set after application.
Solution: After applying Sirenn Lash Seal, avoid touching your lashes and allow the adhesive time to fully cure before getting them wet.

4. You didn’t clamp your lashes after sealing
Clamping helps distribute the adhesive evenly and creates a stronger bond between your natural lashes and the lash clusters.
Solution: Apply a small amount of Sirenn Lash Seal to your applicator before gently clamping your lashes together. This helps seal the lashes from both the top and bottom while reducing the chance of accidentally pulling the lash segments off during clamping.

5. Your lash segments are sticking together
If the adhesive hasn’t been properly sealed, neighbouring lash segments may stick together, making your lashes feel stiff or sticky.
Solution: Once you’ve applied Sirenn Lash Seal and gently clamped your lashes, use your applicator or a clean spoolie to carefully separate any lash segments that may have bonded together.

Still feeling sticky?
If your lashes still feel sticky after following these steps, you may have used too much Sirenn Lash Glue or not enough Sirenn Lash Seal. A thin layer of adhesive combined with enough Lash Seal will always give you the most comfortable, longest-lasting results.
If you’re using InstaGlue Tabs, applying an extra light layer of Sirenn Lash Seal is often all that’s needed to remove any remaining tackiness and leave your lashes feeling comfortable.

Your Sirenn Lashes should feel lightweight and comfortable. If they feel uncomfortable, pokey, or like something is in your eye, it’s usually due to the placement of the lash segments rather than the lashes themselves. The good news is that a few small adjustments can make a big difference.

1. Your lash segments are too close to your waterline

This is the most common cause of discomfort. If the lash band is touching your waterline, it can cause irritation or a poking sensation.

Solution: Remove the lash segment and reapply it approximately 1-2 mm away from your waterline, ensuring your natural lash roots remain visible. If you haven’t applied Sirenn Lash Seal yet, there’s no need to use Sirenn Lash Off. Simply reposition the lash segment before sealing.

2. A lash segment is touching the inner corner of your eye

The inner corner of your eye is very sensitive, and placing a lash segment too close to it can cause irritation or discomfort.

Solution: Leave a small gap at the inner corner, or use a shorter lash segment if needed. Your lash map doesn’t need to start at the very first natural lash.

3. The outer corner is under too much tension

For some eye shapes, placing a lash segment all the way to the outer corner can create tension as your eyes move throughout the day.

Solution: Try leaving the last 2 to 3 natural lashes on the outer corner without a lash segment. This creates a more comfortable fit and can also help prevent lifting.

4. A lash segment isn’t sitting correctly

Sometimes a lash segment can be applied at a slight angle or may not be sitting flush against your natural lashes, making it feel uncomfortable.

Solution: Before applying Sirenn Lash Seal, gently adjust or reapply the lash segment until it feels comfortable. Once you’ve applied Lash Seal, the adhesive is locked in, making adjustments more difficult.

5. Always do a blink test before sealing

Before applying Sirenn Lash Seal, gently blink your eyes a few times, then blink a little more firmly. This helps you check whether every lash segment feels comfortable and ensures that nothing is touching your waterline or the inner corners of your eyes.

Solution: If you notice any poking, discomfort, or irritation during your blink test, adjust or reapply the lash segment before applying Lash Seal. If you haven’t sealed your lashes yet, there’s no need to use Sirenn Lash Off. Simply reposition the lash until it feels comfortable.

Taking an extra minute to do a proper blink test before sealing will help ensure your Sirenn Lashes feel lightweight and comfortable throughout the day.

6. Your lash map may not suit your eye shape

Every eye shape is unique. A lash map that looks beautiful on someone else may not always be the most comfortable or flattering for you.

Solution: Experiment with different lash maps, lengths, or styles until you find the one that feels the most comfortable and complements your eye shape.

Remember

Sirenn Lashes are handcrafted from premium Korean PBT fibres, making them soft, lightweight, flexible, and comfortable for everyday wear. When applied correctly, your DIY lashes should feel so lightweight that you barely notice you’re wearing them.

If your lashes continue to feel uncomfortable after trying these tips, our team is always happy to help you troubleshoot your application and find the perfect fit.

If your DIY lashes look uneven after application, don’t worry. This is a common issue when you’re still learning your lash map or applying lash segments for the first time. With a few simple adjustments, you’ll achieve a much more seamless, balanced look.

1. You’re applying one eye at a time

Applying a full set to one eye before starting the other can make it more difficult to keep both eyes symmetrical.

Solution: If you’d like your lashes to look as identical as possible, apply your lashes to both eyes at the same time. For example, apply your first lash segment to your left eye, then the matching segment to your right eye. Continue alternating between each eye until you’ve completed your lash map. This makes it much easier to keep both eyes even.

2. Your eyes may not be exactly the same size

Most people’s eyes are slightly different shapes or lengths, so using the exact same number of lash segments on each eye doesn’t always create the most balanced result.

Solution: Don’t be afraid to adjust your lash map. One eye may naturally require one extra lash segment or a slightly different placement to create an even, symmetrical appearance.

3. Your lash segments aren’t following your lash map

Applying lash segments in the wrong order or using different lengths can make your lashes appear uneven.

Solution: Lay out your lash map on your silicone lash pad before you begin applying your lashes. This makes the application process quicker and helps ensure both eyes match.

4. Your lash segments aren’t overlapping

Small gaps between lash segments can make your lash line appear uneven.

Solution: Slightly overlap each lash segment by 1-2 mm to create a seamless, continuous lash line.

5. Your lash segments aren’t sitting at the same height

If one lash segment is positioned higher or lower than the others, it can interrupt the overall shape of your lashes.

Solution: Apply each lash segment approximately 1-2 mm away from your waterline, keeping them aligned along the same lash line.

6. Your lash map may not suit your eye shape

A lash map that looks beautiful on someone else may not always suit your own eye shape.

Solution: Experiment with different lash maps, lengths, and styles until you find the combination that best complements your eyes. Small adjustments can make a big difference to the final result.

7. Do a final comparison before sealing

Before applying Sirenn Lash Seal, take a step back and compare both eyes in the mirror. This is the perfect time to make any final adjustments.

Solution: Complete your blink test, check that both eyes look balanced, and make any necessary adjustments before applying Sirenn Lash Seal. Once you’re happy with the result, seal your lashes to lock everything into place.

Remember

Perfectly symmetrical lashes don’t always mean using the exact same number of lash segments on each eye. Since every eye shape is unique, making small adjustments to your lash map will often create the most natural and balanced result.

With practice, you’ll quickly learn what works best for your unique eye shape and create beautifully even DIY lashes every time.
