As a lash artist you have probably experienced a problem with adhesive by now. There are dozens of factors that come into play with both adhesive reliability and client retention. Here we will cover the most common along with suggestions to try and avoid those factors.

Please note that, here at Lash Tavern we track our adhesive batches very carefully. All of our adhesives are manufactured in low quantities very frequently. We track any adhesive complaint and monitor these batches. If there is ever a complaint rate of more then 5% of any batch (that's only 5 out of 100!) we will offer free replacement for those adhesives. We are happy to report that to date we have never been left in this position and we feel strongly about the quality and reliability of our adhesive (minus any of the below exterior conditions).

Factors That Affect Adhesive Reliability

Choosing the Right Adhesive

Adhesives are like shoes. Some are good for the beach, some for the ski slopes, some for the coast and some for inland. What one person loves just might not suit you and vica versa.

The best way to find out an adhesive is for you is to try it. Before purchasing your adhesive it is good to identify it's basic qualities, primarily humidity suggestions and grab time (how fast the adhesive will hold to the lash).

Humidity Suggestions - this is the recommended humidity range for your work environment. Sometimes you may need a humidifier/de-humidifier to reach these levels depending on you climate. Adhesives will typically work outside of their humidity suggestion however at higher levels you will experience a faster working adhesive and at lower humidity levels you will experience a slower working adhesive. Our adhesives are optimal at a 45-55% humidity range with our Expert Series more suitable for dryer climates.

Grab Time - Different lash artists require different working time with adhesives. More proficient lash artists will look for an adhesive with a quick grab time while artists newer to the industry (or technique) or who like time to shimmy the lash will look for and adhesive that has a little longer grab time. Having an adhesive that starts to grab prior to being placed on the lash will drastically effect retention. Our Expert Series adhesive has a grab time of 1-2 seconds under optimal conditions and our Pro-Classic Series adhesive had a grab time of 3-4 seconds under optimal conditions.

Different times of year (seasons and climates) may make your adhesive respond differently then you are used to.

Transportation / Delivery

Depending on your location and the extremes of your weather this can play a large factor. An adhesive that sits in a hot mailbox in the sun may experience a chemical change that affects reliability and consistency.

If you are located in one of these areas, we recommend:


  • Monitoring your package's progress using the tracking number we supply for you and immediately retrieving your package.
  • Using our 'Signature Delivery' service. This insures that your package is delivered directly to a person instead of sitting in your mailbox. You can add this option to any order on the 'Checkout' page, directly below your address.
Storage Prior to Opening

Once you receive your adhesive you will want to place it in an air tight container with the provided silica package. Prior to opening store in a freezer (recommended) or refrigerator. Your adhesive will keep for up to 12 months when stored properly prior to opening.

Work Envirnoment / Humidity

Your work environment’s humidity levels are a critical component when it comes to eyelash extension adhesive performance. With humidity levels that are higher then your adhesive recommends your adhesive will experience a more then ideal level of exposure to hydrogen which will lead to premature curing of the adhesive. This will result in a sub-par bond with the natural lash and likely poor retention.

With humidity levels that are lower then your adhesive recommends your adhesive will take a longer then usual time to grab which will result in stickys and tangles.

Every lash technician’s work space should include a hygrometer. This will allow you to confirm your humidity levels and make adjustments if necessary.


Shaking: EACH TIME prior dispensing adhesive it is important to shake your bottle of adhesive for FULL 30 seconds. Be sure to count out 30 seconds, it is longer then you think (and will give you a decent workout)! This will help to evenly distribute the ingredients of the adhesive which is critical for adhesive performance.

Burping: Once you are ready to put the cap back on your adhesive bottle, be sure to burp the adhesive. To do this, hold the bottle upright and gently squeeze the bottle or tap on the side of the nozzle to clear the nozzle of any adhesive. Once the burping is complete you can now firmly tighten the cap of the bottle and place in your air tight container.

Monitor Humidity: During application you will want to monitor your humidity levels with a Hydrometer to ensure consistency.

Introduce Hydrogen: The use of a nebulizer or nanomister can help greatly when it comes to retention.

Cleansing of the Lashes: Making sure your client's lashes are cleansed properly, dried completely and the primed with a lash primer is an essential part to a good foundation for a successful set.

Storage After Opening

Prior to opening your adhesive you will want to make sure to bring it to room temperature.

Once opened, keep your adhesive in an airtight container with the supplied silica packet. Store in an upright position at room temperature in a cool/dark location.

Client Care and Education

It is important that clients are well educated as to how to care for their eyelash extensions. This is vital to the success of the set and optimal retention. Things such as completely avoiding all oil products, routinely cleansing their lashes and avoiding extremes in temperature are just a few of the important points to make. It is a good idea to supply comprehensive care instructions to every client.

With all these factors considered, consistency is important and being aware of your adhesive and how it is performing is essential for all lash artists. If in doubt, switching to a fresh bottle of adhesive is always the best option. This will help to ensure your clients receive the best quality eyelash extensions possible.
