Common Mistakes to Avoid When Applying Eyelash Extensions

Applying eyelash extensions is a delicate skill that requires precision and attention to detail. As a lash artist, it’s essential to avoid common mistakes that can compromise the quality of your work or your client’s safety. In this article, we’ll cover some of the most frequent errors in eyelash extension application and how to avoid them.

1. Using Too Much Glue

One of the most common mistakes is applying too much adhesive. While it may seem like a good idea to use extra glue to ensure the extensions stay in place, it can actually cause several issues. Too much adhesive can create clumps, weigh down the natural lashes, and make the extensions look unnatural. It can also cause irritation to the eyes and potentially damage the natural lashes. The key is to use just a small amount of adhesive – enough to securely bond the extension to the natural lash, but not so much that it becomes noticeable or uncomfortable.

2. Not Isolating Lashes Properly

Isolating each natural lash before applying an extension is crucial for achieving a clean, professional look. Failing to isolate lashes properly can result in multiple lashes being glued together, creating clumps and uneven extensions. This can lead to discomfort for the client, as well as premature shedding of the extensions. To avoid this mistake, make sure to use proper isolation tools such as tweezers and always ensure that each natural lash is separated before applying an extension.

3. Using Inappropriate Lash Lengths or Curls

Choosing the right lash lengths and curls for your client is essential to achieving a natural look. Using lashes that are too long or too curly can make the extensions look unnatural, heavy, or out of place. It’s important to take into account your client’s natural lash length, eye shape, and desired look before selecting lash extensions. Customizing the length and curl to suit your client will result in a more flattering and comfortable outcome.

4. Not Giving Enough Time for Drying

After applying the extensions, it’s important to allow enough time for the glue to fully dry and set. Rushing this process can lead to the extensions not adhering properly and may cause them to fall out prematurely. It’s essential to allow at least 24 hours for the adhesive to cure properly before the client exposes their lashes to water, sweat, or heat. Remind your clients about the importance of avoiding moisture during the first 24 hours after their lash appointment to ensure the longevity of their extensions.

5. Neglecting Hygiene

Hygiene is vital when it comes to eyelash extensions. Using dirty tools or not sanitizing properly can lead to bacterial infections, irritation, and other complications for the client. Always ensure your tools are clean and disinfected before each session, and make sure to follow proper sanitation protocols. Also, it’s important to check the cleanliness of the client’s eyes and lashes before starting the procedure to ensure there is no makeup or debris that could interfere with the application.


By avoiding these common mistakes, you can ensure that your eyelash extension applications are safe, professional, and long-lasting. Remember, practice and attention to detail are key to becoming a skilled lash artist. Keep learning and refining your technique to provide the best results for your clients and build a reputation as a top lash professional.
