Why Your Lash Glue Isn’t Holding: Common Mistakes and How to Fix Them

If you’re a lash artist or someone who regularly gets eyelash extensions, you know how frustrating it can be when lash glue just doesn’t seem to hold. One of the most common issues lashes professionals and clients face is lashes falling off too soon, and the cause often lies in the adhesive. Whether it’s a lash artist troubleshooting a client’s extensions or someone trying DIY lashes at home, understanding why the glue isn’t holding is crucial for achieving a long-lasting look.

Let’s dive into some of the most common mistakes and how you can fix them to ensure a flawless lash application every time.

Incorrect Glue Selection

Not all lash glues are created equal. Different types of adhesives are designed for various purposes, and choosing the wrong one can impact the hold.

Common mistake: Using a glue that’s too weak for the type of lash extensions you’re applying or one that’s not compatible with your client’s skin type.

How to fix it: Always select a glue that matches your needs. If you’re working with volume lashes, opt for a stronger adhesive. For sensitive clients, look for glues that are hypoallergenic. Also, consider the humidity and temperature of your environment. Glues designed for high-humidity areas work better in more humid conditions, while others work best in dry climates.

Improper Adhesive Application

The way you apply the glue plays a significant role in how long it lasts. Over-application or under-application can both cause problems.

Common mistake: Applying too much glue, which can cause clumping, or too little, which leads to weak adhesion.

How to fix it: The key to perfect glue application is moderation. When applying the glue, ensure you’re coating the lash extension lightly, just enough to adhere to the natural lash without excess glue dripping or pooling. Use a micro-swab to apply the glue evenly, and avoid touching the skin with the adhesive.

Lash Prep and Cleaning

One of the most critical yet often overlooked steps in lash application is proper lash prep. If the natural lashes aren’t clean or oil-free, the glue won’t adhere as well.

Common mistake: Not cleaning the natural lashes or using a lash primer before applying the extensions.

How to fix it: Always clean the natural lashes before starting the application. Use an oil-free makeup remover or a gentle lash cleanser to remove oils, makeup, and other residue. A primer can also help balance the pH of the lashes and create a more effective bonding surface. This step is vital for ensuring the glue can grip the lash properly.

Not Allowing the Glue to Dry Completely

Rushing through the lash application process or not giving enough time for the glue to dry properly can lead to lashes falling off prematurely.

Common mistake: Not allowing enough time for the glue to set before moving on to the next step.

How to fix it: After placing each lash extension, allow the glue to cure fully before moving on to the next one. This may take between 2-5 seconds, depending on the adhesive you're using. Be sure to follow the manufacturer's instructions for the drying time and work in a well-ventilated space to help the adhesive cure more effectively.

Environmental Factors

The environment plays a big role in how well your lash glue holds. Factors like humidity, temperature, and airflow can all impact the setting time and strength of your adhesive.

Common mistake: Working in an environment that is either too dry or too humid, which can either cause the glue to dry too fast or too slow.

How to fix it: Aim for a humidity level of around 40-60% and a temperature of 68-72°F (20-22°C) for optimal glue performance. Use a humidity meter to monitor the conditions in your room and adjust them if necessary. If you’re working in a high-humidity area, consider using glue that’s designed for those conditions, and vice versa for drier environments.

Expired or Old Glue

Like any product, lash glue has a shelf life, and using expired or old glue can significantly reduce its effectiveness.

Common mistake: Using glue past its expiration date or has been opened for too long.

How to fix it: Always check the expiration date before using any lash glue. Make sure you replace your adhesive regularly, especially if it’s been sitting open for a while. Store glue in a cool, dry place away from direct sunlight, and keep the cap tightly closed to prevent it from drying out.

Getting the lash glue to hold perfectly requires attention to detail and knowledge of what can go wrong. From the environment and lash prep to the right glue and proper aftercare, every step in the process affects how well the lashes will stay in place. By avoiding these common mistakes and following best practices, you’ll achieve a longer-lasting, stunning lash look for yourself or your clients. Happy lashing!
