Retention is the quiet metric that decides whether a lash client rebooks. Stunning fans mean little if they shed within days.
Most retention failures trace back to three things: humidity during cure, lash preparation, and adhesive handling.
Cure conditions
Cyanoacrylate adhesives polymerise with moisture in the air. Too dry and the bond is brittle; too humid and it flash-cures before placement. A hygrometer is not optional equipment.
Prep is the bond
Oils and product residue are the enemy of adhesion. A disciplined cleanse-and-prime routine does more for retention than any premium glue.
