The natural cycle of eyelash loss is continuous, and people typically lose 1 to 5 natural eyelashes every day. This means that you could lose 1 to 5 eyelash extensions per day as well. This is perfectly normal and expected, regardless of whether you have eyelash extensions or not. The extensions are applied in a way that allows the natural cycle to continue as usual.
The detachment of eyelash extensions reflects the natural detachment of the natural eyelashes they are attached to. So, if you normally lose 2 to 5 lashes per day, you're likely to lose about the same amount of eyelash extensions per day. It usually takes a few weeks for growth, so eyelash extensions typically last for 2 to 4 weeks. On average, we lose about five natural eyelashes every day.
In a week, that adds up to 35 lashes (which is approximately 20% of the eyelash extensions in a set). This is considered normal and healthy shedding. If too little adhesive was used and the extensions don't adhere properly to the natural lashes, they will simply come off. Certified eyelash stylists Asako and Naoko, owners of Divine Lashes, suggest informing clients about the natural cycle of eyelash loss and seasonal consequences so their expectations are well adjusted from the start.
There's no need for a break between extension sessions when applied correctly. Eyelash tape is an essential tool for any eyelash professional as it ensures that the extension is carefully glued to the natural lash and that no skin comes into contact with the glue. If your client experiences an alarming amount of natural lash loss (where extensions are placed) in a short period of time, check if they are taking any medications. Medical conditions such as alopecia areata, trichotillomania's tangle, chemotherapy and thyroid condition can cause eyelash extensions to fall out faster.
Touching and rummaging can also become commonplace and your client may end up pulling on their natural lashes and damaging the follicles without even realizing it. Several clients have had eyelash extensions with Asako and Naoko for many years without taking a break and their natural lashes remain healthy. To ensure your clients' lashes last a long time, it's important to understand all the factors that contribute to this.
