Double the Bond, Double the Capabilities!

Our upgraded dual-sided bottle holds nearly double the amount of bond from our previous bottle. Choose your vibe: clear or Black formula Each bottle features two applicators for the ultimate precision—one side has a narrow-tip brush for precision application straight onto the spine of the Underlash, while the other has a micro-mascara wand to coat every lash just right.

Gentle on the Eyes, Strong on the Hold

Made with sensitive eyes in mind, our formula hypoallergenic and free from formaldehyde, cyanoacrylate, and latex. It’s all about long-lasting wear without the irritants. Get ready for your most comfortable, effortless lashes yet.

Our Lash Extension Glue Nourishes Your Natural Lashes

Crafted with nourishing components, The Bond not only provides effortless application but also offers vital protection to the roots of your natural lashes. Enjoy the exquisite longevity of your Underlash extensions for an impressive duration of up to 7 days - without risking any damage. Say hello to prolonged beauty and goodbye to worries (and goodbye to your lash lady!)

We suggest using the brown bond that dries clear on Brown lashes and the Black bond with the black lashes.

Don't overthink it, it's just the colour of the bond that sits between your natural lash and Underlash extension.

Prep Your Lashes: Grab The Bond and start with the side that has the mascara-like brush. Apply a light coat to your natural lashes, working from the root up to about halfway—not like mascara! Just a small amount will do. (Pro tip: Wipe any excess product off the brush before applying.)

Coat the Lash Segment: Next, take your Underlash segment and flip to the other side of The Bond with the precise tip. Gently brush along the spine of the lash segment for a secure hold. If you’re looking for even longer-lasting wear, wait 30 seconds, then apply a second layer.

Let It Set: Wait another 30 seconds to let the bond do its magic. Remember, Hun, a little goes a long way! For your first few applications, try using just one coat and see how they hold—then level up to the stronger hold technique next time if needed.

To ensure optimal performance and longevity of your lash bond, please follow these care instructions:

Secure Bond Closure: After each use, make sure to tightly close the bond to prevent excess air from entering the product. The introduction of too much air can cause the bond to become tacky and dry.

Controlled Product Dispersal: This lash bond is specifically designed to dispense a small amount of product onto the wand. Initially, the product may appear "dry," but this is completely normal. The grooves on the wand are intended to accommodate your natural lashes, allowing the bond to deposit the appropriate amount onto them. Avoid applying the bond like a mascara.

Temperature Considerations: If the current temperature in your country falls below 0 degrees, we advise against ordering this product. The formula is not designed to withstand cold temperatures, and we cannot be held responsible for any issues that may arise as a result of disregarding this warning.

Proper Storage: Store the lash bond in an upright position in a cool, dry place away from direct sunlight. This will help maintain its quality and effectiveness over time.

By following these care instructions, you can maximize the performance and durability of your lash bond.

Easy to put on

Still be my favourite DIY lashes

Easy to apply and amazing results for a mum of

Easy to apply and amazing results for a mum of two takes less then 15 minutes to have beautiful lashes

Easy to apply, but not waterproof

Very easy to apply with the tip section, would have loved if it was clear though and also didn’t realise they are not waterproof! Bought these lashes to wear on my Greek holiday. I went in the ocean every day even though I know they weren’t waterproof and surprisingly they lasted longer than I thought.. still got about 5 days out of them.

Beautiful, but did not last.

They look beautiful and were relatively easy to apply, however they didn't last more than a couple of days, which is not what I was hoping for unfortunately.

best lashes I've found

So I was hopeless at putting on false lashes until now - these have been the easiest ones to date and they stay on for ages

Easiest experience ever!!

I have been using DIY lashes for a couples years now and of all the lash clusters I’ve ever used. This by far has been the best, it’s hassle free, super durable, super cute and always on the go. The lash quality is incredible and the bond and seal are fantastic as I have very sensitive eyes and the best part is that I’ve never lost any of my real lashes when using these and taking them off. I couldn’t be happier xx

Great lash glue

I have used this and the brown glue, holds well and doesn’t irritate my eyes. My lashes will generally last a whole week!

Amazing glue

Glue doesn't budge nor irritate my eyes. Lasts an entire week

Great glue. Dries a little quickly

Glue works very well and is user friendly, however i do find that it dries up inside the bottle a little quickly. Due to having it open whilst applying with the tip. It is still usable but it gets a bit clogged up.

Almost mistaken for super glue?!

This stuff does not budge! I've used both black and clear bond. Cant wait to use the newest brown bond formula!

One of the better lash glues

I had to quit salon lashes a few months ago due to an allergy, and have tried so many products to get my lashes back! Other glues I've tried set hard, and make lash clusters crunchy and uncomfortable once they fully dry. This one stays soft and pliable, with a consistency that's a bit like sticky dots, which I can't see or feel after a few hours like with other brands. It keeps lashes in place, but they slide off gently when removing without pulling on my natural lashes. It's also easy to remove from the lash segments, so I can use the same cluster if I stuff up application and need to redo, instead of having to chuck a brand new lash segment. The only downside is my lashes get uncomfortably sticky if I apply glue with the brush like you're supposed to, so I use the tip end instead to apply just to the base of the clusters, and that's been a game changer - retention with no stickies! It's more exxy than other brands, but worth the investment.

Best Lashes!

I have been using these for years now. I love them!

Works really well

Very happy with this product after trying a few others.

Best DIY lashes!

I used a few different brands of DIY lashes and Underlash is by far the best!
They're extremely lightweight and easy to apply. The different length also give a more natural look

The best bond, seal and remover

I have sensitive eyes and when I could no longer have eyelash extensions due to the allergy reaction I’d developed to the glue, I found Underlash. I have no reaction to the bond, seal or remover. The bond holds the lashes for up to 7 days (and I use oils on my face) and it’s so easy to use (once you get the hang of it). One of my fave product kits that I will buy again and again!

Thank goodness! Allergic to every other glue out there BUT NOT THIS ONE

So I’ve been searching high and low and I’m so glad I tried this one out! I have to say first I didn’t actually receive the “Duo” though I received the microbrush tip only but I emailed them and thankfully they sent me the right one I still haven’t received it but in the meantime I have been using the micro tip version and I’m in love!?! And haven’t had an allergic reaction to it!!! I don’t keep my lashes on for more than two days. I like washing my face at night. So I can’t speak on the glue lasting for more than that. But for the length I keep my lashes on I can’t complain. I love it. Staying power for me was great. Dry time is just right. I haven’t noticed it turning white on me. I’ll be a forever underlash customer

Bond Duo

Loving the duo with the brush and tip as opposed to just the brush. The bond works great on my lashes and can easily get a week out of them combined with the seal

GIRRRRLLLLLLL

Let’s just say I LOVE LOVE LOVE these lashes! Super easy super comfortable and I’ll definitely be coming back to order more! 😍

Love it

I have both the black and the white or clear bond and I love the black, makes the glue itself less visible but gives the lashes a pop. Would be interested to see if a brown would look good too!

Bond

What a disappointment with this glue. I couldn't tell you if it works or not since it was almost completely dried up. Would not recommend just based on that.

Hi Jane,

Have you contacted us regarding your bond? Due to a high volume of orders, we unfortunately can't open and check every bond that is distributed. It sounds like this is a manufacturing issue and can be easily fixed by sending you a replacement. Please contact us at hello@underlash.com.au.

Easy to use

Hands down the best bond I have used so far. The applicator is the perfect size for stamping the bond to the base of the lashes making application much easier.

The bond and seal

Best glue in the market ! Will definitely purchase again.

Bond

i love this bond, the downside of this bond is it leaves white things once its dry. but it does the job.

Natural lashes

The seal

Love the seal !!

Clear Bond!!

I love the clear bond with both the black and brown lashes.. it’s so good!!!

The seal

Love the seal it keeps my lashes on through out the day !! Very happy with it.

Lash glue

Love the lash glue !! Highly recommended

Love the remover !! Helps me remove my lashes. Definitely purchase again.

I'll admit I was skeptical about these lashes lasting for up to a week - but they did! I got 6 days out of mine. The Kit has everything you need in one, especially the very useful applicator tool to both apply and press them on with the special, long lasting glue. Instead of sitting on top of the lashes, they glue on underneath and look so natural. Defiantly worth the splurge!

I was first introduced to Underlash while working on a shoot for the brand, I was amazed at how easy they were to apply and how natural they looked, I’ve never been a fan of eyelash extensions on my clients as they can look too fake. Underlash lashes enhance the clients eye’s without over powering, I always recommend underlash to my brides who want longer lasting lashes for their celebrations over extensions every time, there is no comparison. There is no damage to the natural lash either which is another reason i love them so much!
