Our Lash Primer is specifically engineered to restore essential moisture to natural lashes after deep cleansing, allowing the adhesive to bond perfectly. This updated formula, available in both tropical Coconut and Unscented versions, is bottled in recyclable glass packaging with a built-in pipette for precise, mess-free application.
Who is the Lash Primer for?
This product is an essential staple for every professional lash technician, from beginners to advanced artists, who wants to ensure their sets provide the best possible retention for their clients.
What is the Lash Primer?
It is a hydrating pre-treatment solution that rebalances the natural lash after the cleaning process. It helps stabilize the drying time of the glue and significantly improves the overall bond between the extension and the natural hair.
When should you use it?
The Primer should be used as a key step of your pre-treatment routine, immediately after using a Cleanser. It is particularly vital for clients with dry or brittle lashes that need a moisture boost to ensure a secure, "magnetic" attachment.
Why choose London Lash Primer?
Because a well-hydrated lash is a receptive lash. While Cleansers effectively remove oils and debris, they can also strip away necessary moisture; this Primer restores that balance, preventing the adhesive from becoming brittle and ensuring a flexible, long-lasting bond.
Follow these professional steps for a safe and effective application:
Our Lash Primer ensures your prep work is professional and effective, providing the perfect canvas for any classic or volume set.
How should my clients clean their lash extensions?
We always recommend advising clients to use a professional lash cleanser specifically formulated for the delicate eye area and safe for eyelash extensions.
Our Lash Foam Cleanser is designed to:
Using products not designed for lash extensions (like baby shampoo) can lead to dryness, irritation, or poor retention, as they are not formulated for the eye area or adhesive bonds.
For clients with sensitive skin or sensitivities to Tea Tree, a gentle, alternative foaming cleanser is recommended.
To support your clients further, consider providing digital aftercare guides so they can maintain their lashes correctly at home.
My client’s lashes look clean, but retention is still poor — why?
Even when lashes appear clean, residue such as oils, skincare, or microscopic buildup can still be present and affect retention.
If you’re experiencing retention issues:
Also, client aftercare plays a huge role — improper cleansing or exposure to oils can reduce retention significantly.
What’s the difference between Booster and Superbonder?
Both products improve retention, but they work in completely different ways:
Booster (Retention & Speed Booster):
Superbonder:
What’s the difference between Cleanser and Primer?
Both are essential for proper lash preparation, but they serve different purposes:
Cleanser:
Alcohol-based formula
Removes oils, proteins, and residue from natural lashes
Deep cleans the lash surface
Primer:
Water-based formula
Rehydrates lashes after cleansing
Balances pH levels
Prepares lashes for optimal adhesive bonding
Using Cleanser alone is not recommended. Because it removes moisture, skipping Primer can lead to poor curing and reduced retention.
What pre-treatment routine gives the best retention?
A consistent, thorough pre-treatment routine is key to long-lasting results. In many cases, retention issues come down to prep — not the adhesive.
Recommended routine:
Can I use only a cleanser before applying lashes?
For best results, we recommend completing the full pre-treatment routine rather than relying on Cleanser alone.
Cleanser removes oils effectively, but it also dehydrates the lashes. Without restoring moisture using a Primer, the adhesive may cure too slowly
the bonding may be compromised and retention can suffer.
Using both Cleanser and Primer ensures the lashes are properly balanced and ready for optimal adhesion.
