Lash Extensions: What to Know Before Your First Set in Park Slope

What lash extensions are, and are not

Lash extensions are individual synthetic lashes, glued one at a time to your natural lashes with a medical-grade adhesive. They are not strips, not clusters, and not glued to the skin — each extension sits on a single natural lash, sized to match that lash's strength, and rides along until that lash naturally sheds. Done well, they look like your lashes, only longer, darker, and more defined. Done badly, they are heavy, clumpy, and can damage the natural lash.

The skill is in the isolation. A careful artist isolates one natural lash at a time, sizes the extension to it, and bonds it cleanly. A rushed one bonds several lashes together, which causes them to pull at different growth rates and damages the follicle. That is why the artist matters more than the lashes — the materials are similar across shops, the application is not.

Classic, hybrid, and volume

A classic set is one extension per natural lash — the most natural look, your lashes but better, and the right starting point for most clients and the only choice for sparse lashes that cannot carry more. A volume set uses a fan of two to six ultra-fine extensions on each natural lash, building density and drama a single lash cannot — and because each fan is lighter than a classic, it is actually gentler on the natural lash. A hybrid set mixes the two, classics for length and volume fans for density, and it is the sweet spot for a lot of first-time clients.

The right set depends on your natural lashes, your eye shape, and the look you want. A good artist reads all three at the consultation rather than just asking which set you want. The lashes for round eyes are different from the lashes for hooded lids, and an event set is different from an everyday one.

What the appointment is like

A full set takes about two hours. You lie back with your eyes closed, a gel pad protects your lower lashes, and the artist works under magnification to isolate and place each extension. It is quiet, still, and most clients fall asleep — there is genuinely nothing to do but rest. A refill, which refreshes the set as natural lashes shed, takes about an hour and is done every two to three weeks.

There is no pain and no downtime. You leave with defined eyes that need no mascara, and the set holds through showers, sleep, and a normal life for weeks. The only rules are the aftercare: no oil-based products near the lashes, no rubbing, no mascara on the extensions, and a quick brush-through each morning to keep them tidy.

How long they last

A full set sheds naturally over four to six weeks as your lashes cycle through their growth phases. To keep a set looking full, most clients refill every two to three weeks, replacing the shed lashes. Skipping refills does not damage anything — the set just thins — but restarting with a full set costs more than maintaining, so a refill routine is both easier and cheaper.

The clients whose lashes always look full are not lucky; they are on a schedule. Book the refill before you leave the last one and the set never gets thin enough to notice. That is the whole system, and the chair on 7th Avenue makes it easy to keep.
