Faster Lash Glue: Worth the Hype?

Is Fast Lash Glue as Strong as You Think? Why Technique Matters

You don’t need years of experience in the eyelash extensions industry to come across someone asking for the fastest-drying, strongest lash glue, thinking it’s the secret to quicker sets with better retention. At London Lash, celebrating nearly a decade in the industry means we’ve been asked this countless times, and our response never changes: the fastest drying glue doesn’t always guarantee the strongest bond. Here’s why:

Fast Lash Glue = Strong, But Not Always the Best

It’s true—what makes eyelash glue fast-drying and strong comes down to one key ingredient: cyanoacrylate. This compound is responsible for the quick adhesion of the glue, so the higher the amount of cyanoacrylate, the faster the glue dries and the stronger it can be—at least in theory.

The Importance of Humidity in Lash Glue Performance

Here’s the catch: cyanoacrylate reacts with moisture in the air. This means the more moisture (or humidity) in your room, the faster your lash glue will cure. While temperature plays a role too, it’s usually easier to notice fluctuations in temperature than in humidity. If both the humidity and cyanoacrylate levels are high, your glue will dry rapidly.

That’s why it’s essential to track your room’s humidity when choosing a glue for your eyelash extensions. We highly recommend having a Digital Hygrometer to measure room conditions. When asked about the best lash glue, we always inquire about the room’s temperature and humidity, as each lash glue performs best within a specific range. Too much humidity, and your glue dries too quickly, which can affect the outcome.

Faster Doesn’t Always Mean Stronger

While more cyanoacrylate in your eyelash glue leads to faster drying, it also makes the bond more brittle. If the glue cures too fast, especially in a high-humidity environment, it can even shock polymerise, which is what happens when you notice a white residue forming on your lash glue.

Even if your humidity is perfect, there’s another challenge. If the glue you’re using dries faster than your application speed, it will start curing before you attach the extension to the natural lash. So, even with ideal conditions and perfect prep work, fast-drying glue can prevent a solid bond from forming, affecting retention and client satisfaction.

How to Pick the Right Lash Glue for Your Lash Sets

The best eyelash extension glue for your clients isn't necessarily the fastest. It's the one that suits your application speed and room conditions. It’s tempting to go for the fastest and strongest glue, but if it doesn’t fit your working pace, it can compromise your work.

Instead, track your speed. Time how long it takes for you to dip and place a lash extension so you can choose a glue that matches your pace. Whether you're applying classic eyelash extensions, volume lashes, or wispy lashes, the goal is always the same: a strong, long-lasting bond.

To get the best results, don’t just rely on the glue. The right tools also play a significant role in creating the perfect eyelash extensions set. Be sure to use under-eye patches, micropore tape, eyelash primer, and keep eyelash glue remover on hand. A well-prepared eyelash extension kit, combined with the right lash cleanser or lash shampoo, will help you deliver flawless results every time.

So, while faster glue may sound appealing, it’s crucial to pick a product that aligns with your specific room conditions and speed. It’s not worth losing clients over a glue that doesn’t suit your process. Keep your clients’ lashes strong and healthy by choosing the right glue for every unique set.
