Booster vs Primer vs Bonder: What’s the Difference & How to Use Each LashPals Retention Essential
If you’ve ever wondered, “Do I really need a primer, bonder, and booster?” — you’re not alone. With so many retention products out there, it’s easy to get confused about what does what.
At LashPals, we created a simple retention trio—Pawsitive Primer, Whisker Booster, and Purrfect Bonder—designed to help your lash sets last longer, look better, and keep clients coming back. Here's how to use each one, and why they’re not interchangeable.
1. Pawsitive Primer – Pre-Cleansing Powerhouse
What it does:
Removes residual oils, dirt, and moisture from natural lashes before application. It creates a clean, dehydrated lash surface for optimal adhesive bonding.
When to use it:
After cleansing with lash shampoo, and before you start lashing—especially useful for oily or combo lash types.
Why it’s unique:
Our formula is gentle but effective, prepping the lash without over-drying or compromising the natural lash structure.
2. Whisker Booster – Bond Maximizer & Adhesion Enhancer
What it does:
Acts like a “glue grip”—you apply it to the base of lash extensions to improve the adhesive’s cure speed and bond strength. It neutralizes residual moisture and boosts the initial attachment.
When to use it:
Before picking up the lash extension—apply a tiny amount to the lash strip or fan base. Works especially well in high-humidity environments or with fast-drying adhesives.
Why it’s unique:
Unlike primer, it’s not for the natural lash—it’s for the extension side. Perfect for techs who want faster attachment and longer retention.
3. Purrfect Bonder – Seal + Lock Aftercare Hero
What it does:
Applied after application, the bonder cures the adhesive from the outside in, sealing the bond and reducing fumes. It helps eliminate stickies, increase retention, and allows clients to get lashes wet sooner.
When to use it:
After your set is complete—apply a small amount at the lash bases using a micro brush. No rinsing required.
Why it’s unique:
Unlike booster and primer, which are used before or during lashing, bonder is a finishing product that locks in your hard work.
Final Thoughts
Using primer, booster, and bonder together isn’t overkill—it’s a retention power move. Each product has its own unique job and, when used correctly, they work together to give you flawless, longer-lasting lash sets your clients will love.
