Step 1: Preparation

Step 2: Applying Speed-lift Adhesive

  • Apply a strip of speed-lift adhesive to the front of the silicone pad.
  • Use the speed-lift lash tool to gently secure the eyelashes onto the pad, ensuring precise placement.

Step 3: Applying LB Duo Perm Gel

  • Use a Micro Brush or speed-lift angled brush to apply Step 1 LB Duo on lashes, leaving a 1-2 mm gap at the root.
  • Apply up to 3/4 of the lashes, avoiding the tips, and distribute the perm in a thick layer evenly from the outer to the inner corner of the eye.

Step 4: LB Duo Timings

  • Refer to the following timings based on the client's natural lash type:
    • Thick Coarse Lashes: 6 - 8 minutes
    • Average Healthy Lashes: 4 - 6 minutes
    • Fine or Thin Lashes: 3 - 4 minutes
  • Start the timer once the perm application is complete for the first eye.

Step 5: Removing Perm

  • After the appropriate timing, use a damp cotton bud to gently remove the LB Duo perm.
  • Work slowly to ensure thorough removal and re-adhere any loose lashes with lash adhesive.

Step 6: Applying LB Duo Step 2 Neutralising Lotion

  • Apply Step 2 LB Duo setting lotion to the lashes using a clean brush, ensuring full coverage.
  • Leave the neutralising lotion on for 8 minutes.

Step 7: Neutralising

  • Remove the Duo neutraliser with a damp cotton bud, following the same process as perm removal.

Step 8: Tinting (Optional)

  • Tint the client's lashes while they're still on the eyelash pads or after removing them.
  • Limit tinting time to 5-6 minutes to avoid over-processing.

Step 9: Removing Tint

  • Use warm damp cotton pads to gently remove the tint, moving in an upward motion.

Step 10: LB Duo Step 3 Nourishing Serum

  • Apply Step 3 nourishing serum to the lashes, gently lifting them away from the pad.

Step 11: Drying and Finishing
