The nail glossary

Every word the salon assumes you know.

BIAB, cat-eye, slip solution, smile line — nail vocabulary in plain English, one honest minute per term. No account needed, no jargon left standing.

Nail charms, gummy charms

3D charms

Small decorative pieces — bears, bows, hearts — applied to the nail and sealed under gel.

Glossary

Aura nails

A soft airbrushed glow — colour blooming from the centre of the nail with no hard edges.

Builder in a Bottle

BIAB

A soak-off builder gel worn as a strengthening overlay on natural nails.

Glossary

Builder gel

Thick, structural gel used to strengthen, build an apex, or sculpt extensions.

Glossary

Cat-eye

Magnetic gel polish — a magnet pulls a ribbon of light through the wet colour.

Glossary

Chrome

Ultra-fine metallic powder burnished over cured gel — a true mirror finish.

Glossary

Cuticle oil

The highest-leverage habit in nail care — flexible skin at the seal edge protects the seal.

SNS

Dip powder

Colour built by dipping into pigmented powder over resin — no lamp needed.

Electric file, efile, nail drill

E-file

The electric rotary tool used for removal, refill prep and cuticle work.

Glossary

Encapsulated

Art sealed inside clear product — flowers, foil or glitter suspended in the nail.

Glossary

Freehand

Art painted directly with a brush — no stamps, no stickers, pure brushwork.

Glossary

French tip

A line at the free edge dividing the nail into base and tip — grammar, not one manicure.

Soft-gel extensions, full-cover gel tips

Gel-X

Full-cover soft gel tips bonded over the whole nail — extensions without sculpting.

Glossary

Glazed donut nails

Sheer milky base + fine pearl powder + gloss — a glow that seems to come from inside the nail.

Glitter ombré

Glitter fade

Glitter dense at the tip dissolving toward the base — the modern way to wear sparkle.

Hydroxyethyl methacrylate

HEMA

The acrylate monomer in most gel systems — and the most common trigger of gel manicure allergies.

Glass nails, syrup gel

Jelly nails

A translucent colour finish — your nail stays faintly visible through the polish, like sea glass.

Glossary

Matte top coat

A top coat that scatters light instead of bouncing it — any colour becomes velvet.

Baby French, skinny French

Micro French

A French manicure with a hairline tip band of one to two millimetres.

Milk bath nails

Milky white

A sheer, cloudy white — white with light in it, your nail line faintly visible through.

Acrylic liquid

Monomer

The liquid half of acrylic — mixed with polymer powder to sculpt a bead that air-cures.

Glossary

Nail prep

The unglamorous first ten minutes that decide whether a set lasts three weeks or one.

Glossary

Ombré

A smooth gradient from one colour to another along the nail, with no visible seam.

Glossary

Overlay

Product over your natural nail at its natural length — strength without extension.

Glossary

Press-ons

Pre-made nails applied with adhesive — the zero-commitment set.

Fill, infill

Refill

The ~3-week maintenance appointment: regrowth filled, structure rebalanced.

Glossary

Sculpted

Extensions built freehand on a form — no plastic tip, pure shaping skill.

Glossary

Slip solution

The wetting liquid that makes polygel workable — slip for the brush, not a solvent.

Glossary

Stamping

Transferring engraved designs onto the nail with a squishy stamper — crisp pattern, fast.

Smile line depth

Tip depth

How far down the nail a French tip's colour band reaches — micro, classic or deep.

Glossary

Top coat

The clear seal over everything — where gloss, matte and durability actually live.

Tortoise nails

Tortoiseshell

A marbled amber, brown and black nail look that mimics real tortoise shell, built with blended gel polish rather than paint.

Velvet cat-eye

Velvet nails

A magnetic-polish finish worked into an all-over fabric-like shimmer instead of a single band.
