Common Mistakes to Avoid When Using Lash Extension Glue

by Bryn Fest

Lash extension glue is an essential tool for professional lash artists, but it can be tricky to use correctly. As a professional lash artist, it’s important to be aware of the common mistakes to avoid when using lash extension glue. In this article, we’ll discuss some of the most common mistakes and how to avoid them.

Using Too Much Glue

Using too much glue can cause clumping, irritation, and even damage to the natural lashes. It’s important to use the right amount of glue for each individual lash to achieve a seamless, natural look.

To avoid using too much glue, start with a small amount and build up as needed. Use a small, fine-tip applicator to apply the glue precisely to the base of the natural lash. This will ensure that you’re not overloading the extension with glue, and that the adhesive is being applied directly to the natural lash.

Applying Glue to the Wrong Area

Another common mistake when using lash extension glue is applying the extension to the natural lash not in a proper way. This can lead to poor adhesion and even cause the extensions to fall off prematurely.

To avoid this mistake, always apply the extension glue to the base of the natural lash. Use a fine-tip applicator, and be sure to separate the natural lashes before applying the glue to ensure that each lash is isolated.

Not Allowing Glue to Dry Properly

One of the most important aspects of using lash extension glue is allowing it to dry properly. If the glue is too fast or too slow for you, it can result in poor retention.

Check that the drying time of the glue complies with your application speed. Also, be sure to isolate each lash during the application process to prevent the lashes from sticking together while the glue is drying. Finally, avoid applying too much glue, as this can prolong the drying time.

Mixing Different Types of Glue

Mixing different types of lash extension glue can be dangerous and can cause poor adhesion or even allergic reactions. Each type of glue is formulated differently and should not be mixed with other types of glue.

Always use the same type of glue throughout the entire lash application process. If you need to switch to a different type of glue, be sure to clean your tools and remove any residual glue from the lashes before applying the new adhesive. Do not mix strong eyelash extension glue and for example, sensitive adhesive.

Using Old or Expired Glue

Using old or expired lash extension glue can be ineffective and even harmful. The glue can lose its strength over time, and the ingredients can break down, causing irritation or allergic reactions.

To avoid using old or expired glue, be sure to check the expiration date on the bottle before using it. Also, store the glue in a cool, dry place away from sunlight to prolong its shelf life. If the glue is past its expiration date or has been open for an extended period of time, dispose of it and replace it with a new bottle.
