Here’s Why Your Lash Glue’s Playing Up and Ruining Your Retention

Alright, babe, let's talk about something that every lash technician dreads: rubbish retention. You've done an excellent set, and the customer is overjoyed, but they return a week later, complaining that half of their lashes have fallen out. Nine times out of 10, the problem is your eyelash glue.

Now, before you throw it out or curse at your lash trolley, let's find out what's going on. Glue is similar to a wonderful friend. But only if you handle them correctly. One incorrect move, and they're off.

1. Your Humidity’s All Over the Shop

Lash glue is a picky little creature when it comes to moisture. Too dry, and it will not cure correctly. Too moist, it cures too quickly, making the connection weaker than a paper straw in a G&T.

If you operate from home or in a salon without a humidifier/dehumidifier, you are at the mercy of the Great British weather, which is notoriously unpredictable. Invest in a hygrometer, honey. That way, you'll know precisely what your room is up to and can adjust things to keep your glue happy.

2. You’re Not Shaking It Enough 

It sounds straightforward, but you'd be amazed how many lash technicians omit the correct shaking. Lash glue has elements that separate over time, so if you don't give it a vigorous shake for at least a minute before usage, you're essentially dealing with the faulty top layer. No wonder it isn't holding.

3. Your Glue’s Too Old 

I know, it seems wasteful to throw it out. But once a bottle is opened, the time starts ticking. Most lash glues have a shelf life of 4-6 weeks after opening. After then, it takes longer to heal, the connections get weaker, and retention decreases. To avoid guessing, write the date you opened the bottle.

4. You’re Dipping Wrong 

If you make small little dips into the adhesive, you're probably not picking up enough to thoroughly coat the extension. On the other hand, if you plunge half of your lashes in there, you'll wind up with clumps that dry poorly. Aim for a crisp, tiny bead that will coat without drowning it.

5. You’re Not Prepping the Lashes Properly 

Even the most expensive glue will not adhere to lashes that are coated with oil, makeup, or skincare residue. Before you begin, always clean your natural lashes thoroughly with lash wash and primer. Also, inform your clients that you are a lash technician, not a magician, so they should not arrive with their faces covered in eyeliner.

6. Temperature Trouble 

Temperature, like humidity, is an important consideration. Most lash glues perform best at temperatures ranging from 20 to 23°C. Too cold, and it will take forever to set. Too hot, and it will cure too quickly. If your salon resembles a sauna or a freezer, your glue will pout.

7. Not Matching the Glue to Your Speed

If you are a rookie technician, a super-fast glue may begin to cure before you have even set the lash, resulting in a weak bond. If you work quickly, a slow-drying glue will just slip about and not set correctly. Choose one that fits your pace; there's no shame in starting slowly and gradually increasing your speed.

Your lash adhesive isn’t out to get you – it’s just got a list of demands longer than a celebrity rider. Keep it fresh, store it right, work in the right conditions, and prep your client’s lashes like a pro. Do that, and your retention will be so good your clients will be texting you weeks later saying, “Babe, I’ve still got half my lashes on!”
