Lash Prep: How to Cleanse Lashes Before Extensions for Perfect Application & Retention

Proper lash prep is the foundation of great eyelash extension results. A thorough, oil-free cleanse removes makeup, sunscreen, sebum and dust so your adhesive bonds cleanly and your client enjoys long-lasting retention. Always cleanse before every full set and infill.

What You’ll Need (Lash Prep Kit)

Pro tip: swap fluffy cotton for lint-free pads to avoid fibres catching on natural lashes.

Step-by-Step: How to Cleanse Lashes

  1. Explain & protect: Let your client know you’ll be cleansing. Ask them to keep eyes closed; place a pad under the lower lashes if you prefer.

  2. Dispense cleanser: Pump a small amount into the lid or a ring. Dip your cleansing brush into the foam.

  3. Clean top & underside: Using gentle, downward strokes, cleanse the lashes, eyelids, and under the lash line. Work from root to tip; small circular motions along the lash line help break down makeup.

  4. Remove residue: Wipe away foam with a lint-free pad.

  5. Rinse thoroughly: Use your rinse bottle to flush both eyes, ensuring no cleanser remains (leftover surfactants can affect bonding).

  6. Check & repeat: If you still see mascara, eyeliner, SPF or oil, repeat the cleanse until the lashes are squeaky clean.

  7. Dry completely: Use your lash drying fan on cool/low until lashes are fully dry and fluffy. Proceed with priming/isolation and application.

Why Cleansing Matters (Fast Science)

  • Oils + makeup = weak bond and early shed

  • Clean, dry surfaces = stronger adhesion and smoother fan wrap

  • Consistent prep = better retention and fewer “my lashes fell out” messages

Common Mistakes (and Easy Fixes)

  • Stinging/tearing: Rinse longer with room-temp water; use less cleanser and keep eyes closed.

  • Foam won’t clear: You’re under-rinsing—flush more thoroughly and blot with a clean pad.

  • Makeup residue at the base: Focus tiny circular motions along the lash line and repeat cleanse.

  • Lint on lashes: Switch to lint-free pads or sponges.

Client Aftercare Reminder (for your script)

“Cleanse daily with a lash-safe cleanser, brush lightly mid-lengths to tips, sleep on a silk pillowcase, and book infills every 2–3 weeks for best retention.”
