Lash Primer – Eyelash Extension Primer
Lash Primer is a pre-treatment product applied to natural lashes before eyelash extension application.
We recommend using our lash primer once you have cleansed the natural lashes, using a Lash & Brow wash.
Using a Lash Primer will help clients with greasy, oily natural lashes who suffer from poor lash retention.
Applying a Lash Primer before applying eyelash extensions will ensure a better lash bond, creating a stronger, great lash retention.
- Apply Magic Primer using a microfibre brush after cleansing with our Brow & Lash Wash
- Comb your natural lashes thoroughly, ensuring they are clean & ready to prime
- Dispense a drop of Magic primer into a disposable glue tray/ring
- Using a microfibre brush, dip it into the Magic Primer & dab off any excess lotion onto the couch roll
- Apply Magic Primer rolling underneath & on top of the lashes in preparation for your eyelash extension application
- Comb your lashes through again & apply your eye patch – ready to lash map
- You’re now ready to start your eyelash extension application
Lash primers help you achieve a quicker eyelash extension attachment to the natural eyelashes by removing any natural oils & eye makeup residue that may be on natural lashes.
Lash primers also balance the PH level of the natural lashes, creating a better bond between the eyelash extensions & the natural lashes, creating better eyelash extension retention!

Yes, Lash Primer is suitable for all eyelash extension treatments & is particularly beneficial for clients with oily natural lashes or those who regularly wear skincare or makeup products around the eyes.
Does Lash Primer replace Lash Cleanser?

Lash Cleanser removes makeup, dirt & surface debris, while Lash Primer removes remaining oils & prepares the natural lashes for optimal lash adhesive bonding.
