Primer comes first. Before any adhesive touches a natural lash, primer cleans the fiber of oil, makeup residue, and dust — the three factors that ruin bond strength. Properly primed lashes retain 30-50% longer than unprimed ones.
Lash primer is a pH-balanced cleansing solution applied to natural lashes before extension placement. The formula dissolves natural skin oils, makeup residue, mascara traces, and ambient dust that interfere with adhesive bonding. Primer also adjusts the lash fiber's surface pH to match the optimal range for cyanoacrylate polymerization, producing a stronger initial bond.

Primer is functional, not cosmetic. Lash retention testing consistently shows 30-50% better retention on primed lashes versus unprimed. Skipping primer saves 2-3 minutes per service but loses 1-2 weeks of average retention.
Two mechanisms: surfactants dissolve oil and residue (mechanical cleaning), and pH adjusters tune the lash fiber surface to 5.5-6.5 (the optimal pH range for cyanoacrylate polymerization). Clean + correct pH = stronger bond.
Facial cleansers contain too many residues (moisturizers, emollients, fragrances) that interfere with adhesion. Dedicated lash primer is formulated to evaporate completely without leaving residue.
Tear-free formula minimizes irritation. Sensitive clients benefit from water-based primer (gentler) versus solvent-based (more aggressive cleaning). Always patch test new primers on the lash line away from the eye before full application.
1-2 drops per eye, applied with micro-brush. A 10ml bottle handles 80-100 lash services. Salons typically reorder primer every 6-10 weeks at moderate volume.
Yes. Lash primer is non-DG cargo — ships by standard courier without hazmat documentation. Easier international shipping than adhesive products.
