Why You DON’T Need a Primer for Your Lash Clients
When it comes to lash retention, many artists are led to believe that a primer is a non negotiable step in their application process. But what if we told you that using a primer might actually be doing more harm than good? Let’s break down the science of lash adhesion and why skipping primer can lead to better, longer lasting results for your clients.
Understanding Lash Adhesion: What Really Matters?
Lash adhesives are designed to bond to the natural lash by creating a polymerisation reaction when exposed to moisture. This means the right conditions — proper humidity, clean lashes, and correct application — are what truly impact retention, not a primer.
Many primers contain alcohol or other astringents that strip away the natural oils from the lashes. While this might sound beneficial, it actually disrupts the optimal moisture balance needed for proper adhesion. Lash glue needs a slight amount of moisture to cure correctly — overly dry lashes can cause poor retention.
Why Using a Primer Can Work Against You
💗 Primers Can Over Dehydrate the Natural Lash
Primers are marketed to “remove oils and residues” from the lashes, but in reality, they often remove too much. The natural lash requires a small amount of moisture for optimal bonding. When you strip this away, the adhesive may not cure properly, leading to premature shedding.
💗 They Can Cause Brittle Bonds
Some primers contain high amounts of alcohol, which can cause the adhesive to set too quickly, creating a brittle bond. Instead of flexibility, the lash extension becomes more prone to breaking or popping off prematurely.
💗 Adhesive Is Designed to Work Without a Primer
High quality lash adhesives are formulated to work effectively on a clean, oil-free lash, without the need for an additional priming product. Many top lash brands and trainers emphasise that proper preparation (like thorough cleansing) eliminates the need for a primer altogether.
💗 Primer May Weaken Adhesion Over Time
Some primers leave behind a residue that can act as a barrier between the lash and adhesive, which can lead to retention issues rather than solving them. Instead of strengthening the bond, it interferes with it.
What You Should Do Instead for Optimal Retention
✅ Focus on Proper Cleansing
A thorough cleanse with a lash-safe cleanser is all you need to prep the lashes. Proper cleansing removes oils, makeup, and debris while maintaining the natural moisture level needed for adhesion.
✅ Understand Your Adhesive’s Requirements
Every adhesive has an optimal humidity and temperature range. Instead of relying on a primer, focus on controlling your environment to ensure your adhesive works at its best.
✅ Use a Nano Mister for Proper Curing
Instead of primer, use a nano mister to lightly introduce moisture and help the adhesive cure correctly. This balances the polymerisation process, leading to better retention.
✅ Educate Clients on Proper Aftercare
Client habits play a major role in lash retention. Ensuring they properly cleanse their lashes and avoid oil-based products will do far more for retention than using a primer ever could.
Final Thoughts: Skip the Primer, Improve Your Retention
Lash primers have been marketed as a must-have, but the reality is that they are often unnecessary and can even negatively impact retention. By focusing on proper cleansing, humidity control, and correct application techniques, you can achieve better, longer-lasting lash sets without needing a primer.
Next time you reach for that primer, ask yourself — do I really need this? The answer is likely no. Stick to science-backed techniques, and your clients will thank you with flawless retention results!
