Lash Extension Glue Options Making Your Head Spin? Don’t Become Unstuck! 


No matter what stage of your lash career you’re at, navigating the myriad of lash extension glues on the market can be overwhelming to say the least. If your head is already spinning, worry not – we’re here to help make everything a little clearer for you so that you can be sure you’re getting the best lash extension glue for you!

Let’s take a look at each of our glues in turn, to give you an idea of what kind of thing is on offer.

Satin Bond

Possibly the best lash extension glue for beginners in the London Lash range, Satin Bond has a 2-second drying time and a ‘medium’ texture – by which we mean it’s not so runny that you have a hard time getting enough on the lash (this is something that comes with practice and the right dipping technique), and not so thick that you consistently end up with too much on the lashes, leaving you with stickies (something which also comes with practice). 

Satin Bond works best in humidity levels between 50-65% – if your humidity is consistently higher than this, then you may find that Satin Bond is a great fit for you, even if you typically place lashes within 1 second of dipping them. If you’re not sure how long it takes you to place a lash after dipping, try timing it – it makes all the difference when finding which glue is best for you.

Lady Bond

Lady Bond has been a part of our lash extension glue range since the very beginning of London Lash, and without tooting our own horn too loudly, it has stood the test of time for a really good reason – Lash Techs all over the world LOVE it. 

Lady Bond is user-friendly – it has a 1-2 second drying time, which makes it a great fit for lash techs of almost any level – of course, those super speedy lashers out there will find it a little too slow, but if you’re super speedy and your humidity gets very high in the winter thanks to all the extra snow lying around, you might find that swapping to Lady Bond is a great option. 

TOP TIP: if you don’t already have one, a Digital Hygrometer is a really sound business investment. If that sounds like hyperbole, consider that not knowing your temperature and humidity levels means that you’re choosing a glue based on vibes alone, which is fine for some things, but if you choose the wrong lash extension glue for your environment, your retention will suffer, and at best, you’ll have to redo some lash sets for free. Worst case scenario, you’ll get a slew of poor reviews online and lose a bunch of clients. When we say it’s worth knowing your room conditions and keeping track of them, we mean it!

Crystal Bond

As the name suggests, Crystal Bond is a clear lash extension glue. It’s especially popular for lash sets that use coloured lash extensions, as it provides a seamless glue bond between the extensions and the natural lashes, but it can be used for any type of eyelash extension set.

Like Lady Bond, Crystal Bond has a 1-2 second drying time and a medium consistency, so in theory, it is a good fit for all of the same Lash Techs; however, the lack of black pigment means that it’s a bit harder to see on the lashes, so you can quite easily end up with too much glue on the bases of your lashes, leading to stickies and a messy finish.

Lastly, with any clear lash extension glue, it’s really important to ensure that your glue is perfectly mixed. With black lash extension glue, you can tell when you dispense if you haven’t shaken it properly because it will have a gray appearance. This isn’t the case with clear lash extension glue as there is no pigment to separate out from the cyanoacrylate and the stabilizers, so you need to really be vigilant and thorough when it comes to shaking your glue.

Flexie by name, Flexie by nature. We called it Flexie because it wraps around the lashes and the extensions, forming a gorgeously flexible bond that helps to prolong retention. Flexie has a 1 second drying time in quite a wide range of humidity levels (something else that gives it its ‘flexible’ name), which makes it perfect for Lash Techs who are used to working more quickly, especially if they find that their humidity levels are prone to fluctuating between 40-70%.

TOP TIP: Two top tips in one post? Don’t say we never treat you! On the subject of humidity, we really need to make it clear that humidity doesn’t just affect your glue during use. Taking extra care of your lash extension glue between uses is just as important, if not more, as paying attention to your room conditions while you work. Ensuring your glue nozzle is kept clean and screwing your lid on tightly to keep it airtight, and storing it properly in between uses can make all the difference to your glue’s performance and to your lash extension retention. Take a look at this blog post next for a rundown of all the glue care accessories you can get, with some tips about what is essential and what you can add to your collection later down the line.

Power Bond

Power Bond is Lady Bond’s right-hand man – it’s been part of our collection since day 1 and has been the go-to lash extension glue for the more advanced Lash Techs due to its super rapid drying time of 0.5-1 second. 

Power Bond is quite particular about the room conditions it’ll work best in, so if you can guarantee stability in your humidity levels, Power Bond will be a great fit if you’re used to placing lashes super quickly.

If you find that your conditions fluctuate, however, allow us to introduce you to…

Royal Bond

If you’ve ever looked at Royal Bond and wondered about its price point in comparison to our other lash extension glues, you’re not alone, but hear us out. Until Royal Bond, if you were a rapid lasher, you’d have Power Bond on hand for some lash sets, and Flexie as well in case your humidity went up too much for Power Bond to work well in. This is, of course, fine, and you’ll find that it’s not uncommon for Lash Techs to use a couple (or even multiple) lash glues depending on any number of factors. 

What Royal Bond does with its humidity preference being between 30-80% is bridge the gap between low humidity working conditions and high humidity working conditions for those Lash Techs who either don’t do enough lash sets to justify having more than one bottle of glue on hand, or who don’t necessarily have the budget to warrant buying multiple glues each month. Royal Bond, in that sense, takes the place of multiple bottles, and streamlines your lash kit if you work quickly and experience fluctuations in your room conditions.

If I may also add an Author’s Anecdote to this: when we were testing Royal Bond back in 2018, my Lash Tech tried out Royal Bond (if it goes well for me, I will have real-life experience to pass on to all of you, and if it doesn’t go well then I can give my honest and unfiltered feedback without it affecting the business’ reputation). It was the best retention I’d ever had, hands down. Based on that, we placed an order, and the rest, as they say, is history.

So now you have a better idea of what each of our glues may offer to you specifically. If you’d like a few pointers about picking a glue based on your room conditions, take a look at this post. If you’re stuck between two glues, try out a sample first to give you a better idea of how well the particular glue suits you.
