How to Apply DIY Lashes Step-by-Step

Create the Tacky Foundation

Prep: Ensure your natural lashes are clean, dry, and free of any residual oils.
Bond: Use the BOND end of your dual-headed wand (the black mascara-style side). Lightly brush a thin layer onto the underside of your natural lashes, focusing on the roots.
Wait: Allow 30 seconds for the bond to become tacky before applying clusters.

Handmade Precision

Select: Choose your desired lash cluster from the tray.
Technique: Using the applicator, gently grasp the cluster near the base.
Lift: Carefully peel the cluster away from the strip to keep the handmade fibers intact.

Invisible Underside Placement

Position: Look down into a mirror and gently lift your eyelid.
Place: Apply the cluster underneath your natural lashes, about 1-2mm away from the waterline.
Repeat: Work your way across the eye to create your custom lash map.

Lock in the 7-Day Hold

Fuse: Once all clusters are placed, use the applicator to gently squeeze (clamp) the clusters and natural lashes together.
Seal: Switch to the SEALER end of your wand (the clear side). Swipe a small amount only where the clusters meet your natural lashes to remove any stickiness and lock the hold.

Damage-Free Exit

Saturate: Apply a dedicated lash remover to the base of the clusters.
Dissolve: Wait 60 seconds for the remover to fully break down the bond.
Slide: Gently slide the clusters off without tugging or pulling your natural lashes.
