As someone who has experienced the challenges of lash extension retention firsthand, finding the right lash glue truly transformed my work. One crucial tip is to avoid applying glue next to a wet fan, as moisture can weaken the bond. Holding the fans in place for about two seconds helps secure the extension onto the natural lash properly without shifting. Applying the extension on top of the natural lash rather than underneath helps with both comfort and retention. I’ve noticed that using a very small amount of glue is much more effective—too much glue can cause clumping and weaker adhesion. Developing a rhythm when dipping the lash into glue speeds up the process and gives consistent results. Matching the glue’s dry time to your speed is essential to avoid premature drying or overworking the adhesive. For example, the ‘magic glue’ mentioned in the tips is highly recommended because it balances fast drying with strong hold, making it ideal for professional lash techs. Don't hesitate to experiment with different glues to find one that suits your style and pace. Also, always keep your glue sealed tightly and stored in a cool, dark place to maintain its effectiveness. Combining these insights can help anyone achieve longer-lasting, beautiful lash extensions that clients love.
