Saline solution vs. primer

When pretreating natural eyelashes before eyelash extensions, the question often arises: Should you use a primer or is a saline solution sufficient? The answer depends on various factors and there is no universal "always" or "never" answer. It is important to consider the client's needs and the properties of the products to achieve the best results.

The primer thoroughly degreases the natural lashes and removes moisture at the same time. As eyelashes can store around 10 % moisture, this removal is important for optimal curing of the eyelash glue, which needs moisture to harden. However, for clients with adhesion issues and non-oily skin, priming can cause the adhesive to only draw moisture from the surrounding air, which can lead to a longer curing time and less optimal hold.

Another scenario occurs with customers with oily skin. Priming is essential here to remove excess oil. After priming, it is advisable to rinse the lashes with a saline solution to restore moisture.

It is important to emphasize that saline cannot completely replace the primer. Although saline is mildly degreasing, it is not as thorough as a primer. Even a homemade saline solution with an increased salt content cannot provide the same thorough degreasing as a primer.
Ultimately, it is crucial to understand the customer's needs and the properties of the products in order to decide on an individual basis which pre-treatment will deliver the best results. This will ensure that each client receives the optimal treatment and that the lash extensions remain long-lasting and beautiful.
