HOW TO USE

STEP 1 • APPLY ADHESIVE
Apply a small, rounded bead of Made for This® Adhesive to the top side of the lash cluster’s bottom edge.
Wait 20–30 seconds until tacky.

STEP 2 • APPLY TO LASH LINE
Using your applicator, apply your segments to the underside of your natural lashes, avoiding your waterline. Repeat for remaining segments.

PRO TIP • CLAMP TO SECURE
Once all segments are applied, gently clamp your natural lashes and segments together using your applicator to fully secure your set and achieve a seamless blend.

Frequently Asked Questions

Your lash questions, answered — everything you need to know about DIY lash clusters.

Can I wear lash clusters if I've never worn false lashes before?

Yes — FlutterHabit lash clusters are designed with beginners in mind. Unlike strip lashes, clusters are applied in small segments underneath your natural lashes, giving you more control over placement and a more natural-looking result. PrepTECH™ technology makes application even easier with pre-placed micro adhesive dots on each segment. And if you're struggling with application, our Application Guarantee offers a free one-on-one Zoom consultation at consultation.flutterhabit.com — and if you still can't get it after your call, we'll refund your lashes and adhesive.

How do I make my lash clusters last longer?

The key to longer wear is using the right adhesive and following a simple aftercare routine. Applying your clusters with Made for This® Adhesive will provide the strongest bond and most optimal wear. Avoiding oil-based products around the eye area, rubbing your eyes, and keeping lashes dry for the first 24 hours after application are all important tips for longevity.

Cleaning your lashes regularly with our Foam-A-Friend Foaming Lash Cleanser will also help keep lashes looking great and extend wear time. With the right care, each set lasts up to 10+ days — and many of our customers report wearing theirs even longer.

What is PrepTECH™?

PrepTECH™ is FlutterHabit's patent-pending technology that places micro adhesive dots directly on each lash segment for easier placement and a more secure bond — no extra prep steps required.

Can I sleep in FlutterHabit lash clusters?

Yes — when applied correctly with Made for This® Adhesive, FlutterHabit lash clusters are designed for multi-day wear, including overnight use.

How do I apply FlutterHabit lash clusters?

Apply a line of Made for This® Adhesive to the top side of the lash segments at the base. Wait 20–30 seconds or until tacky, then use your applicator to place the segment underneath your natural lashes, close to, but not touching the waterline. Once all segments are applied, use your applicator to gently clamp the segments to your natural lashes to secure them in place.

How long do FlutterHabit lash clusters last?

When paired with Made for This® Adhesive and applied correctly, each set lasts up to 10+ days. Individual results may vary based on application technique, skin type, and aftercare.

How do I remove Made for This® Adhesive?

Always use a dedicated lash remover — never pull or tug at your clusters. FlutterHabit offers two removal options: Lash Off™ Removal Spray for a quick, mess-free mist application, or our Lash Removal Balm for a more traditional balm formula. Both dissolve the adhesive gently without damaging your natural lashes.

How do I make my lash adhesive last longer?

Start by keeping your lashes dry for the first 24 hours after application. Avoid oil-based skincare and cleansers near the lash line, don't rub your eyes or tug at the clusters, and clean your lashes regularly with Foam A Friend Foaming Lash Cleanser to remove buildup without breaking down the bond.

Can I use lash extension glue on DIY lash clusters?

No — professional lash extension glue is not safe for DIY use. It contains cyanoacrylate, a powerful bonding agent designed for salon use by trained professionals, and is not formulated for direct skin contact. Using it at home can cause irritation, damage to natural lashes, and is extremely difficult to remove safely. Made for This® Adhesive is specifically formulated for DIY underlash application — strong enough for up to 10+ days of wear, but gentle and safe for at-home use.

Is Made for This® Adhesive safe for sensitive eyes?

Yes — Made for This® Adhesive is latex-free and fragrance-free, making it suitable for most people including those with sensitive eyes. If you have a known sensitivity to carbon black pigment, the Clear formula is a great alternative as it contains no carbon black. If you have a history of eye sensitivities or allergies to cosmetic products, we recommend consulting your doctor before use. As with any eye area product, discontinue use if irritation occurs.

How long does Made for This® Adhesive last?

When applied correctly and paired with proper aftercare, Made for This® Adhesive is designed for up to 10+ days of wear. Avoid water, steam, and sweat for the first 24 hours after application, don't rub your eyes or tug at the lashes, and clean your lashes regularly with Foam A Friend Foaming Lash Cleanser to help maintain the bond. Many FlutterHabit customers report wearing their sets even longer.

What is Made for This® Adhesive?

Made for This® Adhesive is FlutterHabit's signature lash cluster glue, developed specifically for underlash application. Featuring Lash-Latch Technology™, it's formulated to deliver a stronger, longer-lasting bond for up to 10+ days of wear. Available in Black, Clear, and Mini Black.
