As a lash artist in Dublin or anywhere in Ireland, you know that the island’s damp climate can make lash adhesive unpredictable. Too much humidity can cause the glue to cure too quickly, leading to poor attachment and lashes that pop off before the infill. On the other hand, low humidity can slow down cure time and cause stickies. Over the years we have tested adhesives from Russia, Vietnam, China and South Korea to find the perfect formula for our Irish clients. In this guide I’ll share how humidity affects lash glue, what to look for in an adhesive, and why our FAST PRO Ultra Glue has become a favourite for lash artists working in high‑humidity conditions. I’ll also share practical tips to get the best results and answer your most common questions.

**Understanding humidity and lash adhesive performance**
Humidity triggers the curing process in cyanoacrylate lash glues. When the moisture level in the air is high (like it often is in Dublin), glue can polymerise so fast that it loses its bonding power before you’ve placed the extension. Conversely, when it’s too dry the glue stays wet and forms clumps. That’s why adhesives are rated for an ideal humidity range. A quality glue will list the humidity it works best in and how quickly it dries. When shopping for adhesives, consider that European and Korean manufacturers often produce glues optimised for moderate humidity, while some cheaper products from other regions might only work well in very dry conditions. Investing in a professional adhesive designed for our climate saves time and retention headaches.

**Key factors to consider when selecting lash adhesive**
• **Humidity range** – Choose an adhesive that performs in 40–70 % humidity; this covers most Irish conditions.
• **Drying time** – A 0.5–1 second glue is ideal for experienced artists who need speed; 2 second glues give extra time for beginners.
• **Viscosity** – Thicker glues can be easier to control, while thin glues suit volume work. Pick what feels comfortable.
• **Fume level** – Low‑fume adhesives are kinder to sensitive clients and lash artists’ eyes.
• **Retention** – Look for a formula that promises retention of four to six weeks when applied correctly and clients follow aftercare.
• **Shelf life** – Unopened glues should last 6 months; once opened, most should be replaced every four to six weeks.

**Why our FAST PRO Ultra Glue is a game‑changer**
After trialling dozens of glues, we developed FAST PRO Ultra Glue specifically for the humid Irish climate. This professional‑grade adhesive cures in around one second and performs best in 40–70 % humidity, with temperatures between 18–24 °C. That means you can trust it on those muggy summer days and during the chilly wet winters when humidity spikes indoors. The formula is latex‑free and low in fumes but still delivers powerful retention, so your clients can enjoy their lashes for weeks. Whether you specialise in Russian volume or classic sets, FAST PRO Ultra Glue gives you the flexibility to create both. It’s included in our **Lash Pro Essentials Set**, alongside our Strawberry Primer, Basic Lash Shampoo and Remover – everything you need for prep, application and removal in one bundle.

**Application tips for humid environments**
• **Control your environment**: Use a hygrometer to monitor humidity and temperature. A dehumidifier or humidifier can help you stay within the ideal range.
• **Prepare natural lashes**: Cleanse with a gentle lash shampoo and primer to remove oils and improve adhesion.
• **Use smaller glue drops**: In high humidity, glue cures faster. Refresh your glue drop every 10–15 minutes to maintain performance. Our honeycomb glue cups keep drops round and help delay curing.
• **Choose the right tools**: Microfibre brushes help you apply primer precisely without flooding the lash line. Spare glue nozzles ensure your adhesive dispenses smoothly, and LashTech Precision Tape assists in isolating lower lashes when eye pads aren’t enough.
• **Mind your technique**: Dip the extension quickly, isolate the natural lash, and place the extension immediately. In humid rooms you need to work efficiently to avoid shock curing.

**Frequently Asked Questions**

**What humidity should I keep my room at?**  
Aim for 45–60 % humidity. Most professional glues, including our FAST PRO Ultra Glue, perform best in this range. Use a hygrometer to check.

**Can I adjust my glue if the weather changes?**  
Yes. On very humid days, work with a glue that has a slightly slower dry time or lower viscosity. You can also reduce your glue drop size and refresh it more often.

**Why is my adhesive turning stringy?**  
Stringiness often means the glue has been exposed to air or moisture for too long. Change the drop and make sure your bottle is sealed between uses. Replace the bottle every four weeks once opened.

**Do I need a different adhesive for volume vs classic sets?**  
Not necessarily. A versatile adhesive like FAST PRO Ultra Glue works for both. The key is adjusting your pick‑up speed and using the right amount of glue.
