Want more wear from every set? Turn up the heat. Heat fusing warms the bond along the base of your lashes to reactivate it, then a cold fuse with your wand recreates the seal. It's one of the easiest ways to maximize the longevity of your Gossamer® lashes.

Find your bond →How to heat fuse, step by step
- Turn up the heat. After your full Lashify application, turn on your Lashicurl® and set it to the third heat setting. All three lights should be lit.
- Heat and activate. Hold the heat along the Spine™ base of your lash map for about 10 seconds. Warming the bond this way reactivates it.
- Cold fuse. Remove the Wandom® covers from your Fuse™ Control Wand and do a full fuse. The coolness of the wand recreates the seal.
Warm to reactivate. Cool to seal. That is the whole trick.

When to heat fuse
- Right after applying, as a finishing step for longer wear.
- Mid-wear, when a corner starts to lift. See 3 quick touch-up fixes.
- Before a big day, to refresh the seal on a set you've been wearing.
Heat fusing works best on a set built the Lashify way: thin bond layers, Gossamers placed 1–2mm from the waterline and fused on the spine, then sealed. Clients wear their lashes up to 2 weeks by layering bond the Lashify way. How long Lashify lasts →
