Lash Stacking 101: Elevate Your Glam Game

Updated October 2026 · 8 min read

Lash stacking means layering one Gossamer® on top of another to add volume or length. Because Gossamers come as multi-cluster segments, not strips and not single lashes, they stack and blend seamlessly: a stacked strip lash looks like two strip lashes, but stacked Gossamers just look like fuller lashes. Stacking™ is a Lashify original, and it's how one set of lashes goes from everyday to evening.

What is lash stacking?

Lash stacking is an application technique where you layer Gossamers on top of each other. Different techniques use different orientations and arrangements, but they all layer Gossamers to add volume or length to your look. Our lash experts coined the term when they developed the technique.

You can stack on a fresh application, or on a lash map you've been wearing for a few days. Wearing a single layer all week and need a bolder look for Friday? Stack a new style right on top. No need to remove your lashes and start over. Stacking a new layer mid-wear also reinforces the bond of the first layer, so you get longer wear overall.

Gossamers are the lightest lashes in the world: they are made without glue, so nothing in the lash weighs it down. That's why you can stack to your heart's content and still get weightless, comfortable wear for days.

Can anyone stack lashes?

Yes. Stacking takes practice, like the regular Lashify application. Master the basic Gossamer® application first (we call it Level 1), then move on to stacking (Level 2). Start with our guide to applying Gossamer lashes.

Why learn lash stacking?

Stacking lets you design ultra-customizable lash maps that flatter your exact eye shape and style, and wear the same Gossamers in different arrangements for work and nights out. A few looks you can create:

• Eyeliner dupe: stack short Gossamers (8mm, extra short) on top of longer ones for an eyeliner-like effect.
• Subtle color ombre: stack Prismatic Gossamers on top of natural colors of the same length for a soft ombre as the fibers blend.
• Wing it: place slightly longer Gossamers at the outer corners for a winged look.
• Open your eyes: stack the longest Gossamers in the center of the lash line for a doll-eye look.

Volume stacking

Volume stacking is our most popular stacking method, and the one to start with. You stack Gossamers directly on top of one another, with the spines aligned like velcro and nothing dangling off the spine beneath. More fibers working in parallel create a fuller, more dramatic look. You can even volume stack on an application you're already wearing.

How to volume stack

1. Apply your first layer of Gossamers as normal and let it set. For your first stack, we recommend a base layer of Curl.
2. Add a little bond along the top edge of the spines on the base layer. Use clear Whisper Light® to see where you're placing the next layer, or black for an eyeliner-like effect.
3. Wait 30 to 60 seconds for the bond to turn tacky (clear Whisper Light turns clear).
4. Apply the second layer so its spines align with the first.
5. Once every Gossamer® is in place, gently fuse for 15 seconds with the Fuse™ Control Wand, just as you did for the base layer. Done.

Brick stacking

Brick stacking adds dimension and intensity. As the name suggests, you layer the lashes like bricks, with each layer slightly offset from the one before it. It's the technique we recommend for sparse or thin lashes: the offset placement bridges gaps for more even density, and gives the Gossamers more to hold on to for longer wear. Unlike volume stacking, a brick stack has to start from a fresh application, and it's a little more advanced, so try a volume stack first.

How to brick stack

1. Lay the base layer with about half a Gossamer® spine of space between each segment. Apply and fuse as normal. Pro tip: place one Gossamer® on the inner and outer corners to set the boundaries of your "bricks."
2. Once the base has set, apply clear Whisper Light® along the spines of the base layer so you can see the gaps.
3. Wait 30 to 60 seconds for the bond to turn tacky and clear.
4. Apply the second layer one Gossamer® at a time, centered over the gaps in the base layer.
5. When every gap is filled, gently fuse at the lash line, as you did for the base layer. Done.

Length stacking

Not sure about a longer length? Length stacking lets you test it while adding volume. It creates the illusion of longer lashes across the lash line, or only where you want it, like the outer corners. It's beginner-friendly.

How to length stack

1. Apply your first layer of Gossamers as normal and let it set.
2. Apply Whisper Light® along the top of the base layer about 2mm out from the spine, toward the tips. The precision tip makes this easy.
3. Wait 30 to 60 seconds for the bond to turn tacky.
4. Apply the second layer along that line of bond, 2mm out from the base spines, wherever you want added length.
5. Gently fuse for 15 seconds. Done.

One set of lashes. Endless looks. That is the point of stacking.

Questions people ask

What is lash stacking?

Lash stacking is layering one Gossamer lash on top of another to add volume or length. Because Gossamers are multi-cluster segments, stacked layers blend seamlessly.

How do you stack lash clusters?

Apply and set a base layer, add a thin line of bond along the base spines, wait 30 to 60 seconds for it to turn tacky, apply the second layer, then fuse for 15 seconds with the Fuse Control Wand.

What is the difference between volume stacking and brick stacking?

Volume stacking lines the second layer up directly on top of the first for a fuller look. Brick stacking offsets the second layer over the gaps in the first, which evens out density on sparse or thin lashes.

Can you stack lashes on a set you are already wearing?

Yes, with volume stacking. Brick stacking needs a fresh application.

Do stacked lashes feel heavy?

Gossamer lashes are made without glue in the lash, which makes them the lightest lashes in the world, so a stacked set stays light.
