Frequently asked questions
What does the ND gel extension collection cover?
1,109 gel extension SKUs across 7 sub-categories: Builder Gel (LAVIS BIAB V1+V2+Builder Jar 30ml+Non-Sticky Jar), LAVIS Poly Extension Gel V1/V2, Apres Gel-X soft gel extension tips (themed kits Kuromi/Hello Kitty/Gold/Black), LAVIS Dual Form 5-shape kits, LDS Rubber Base Gel Ver 2 Bouncy Blush 30-shade line, Press-On Nails retail line, and Base + Top Gel finish coats. Brand coverage spans LAVIS, LDS, Apres, OPI, Chaun Legend, and CND. Price band $7 to $239.70 wholesale.
What's the difference between LAVIS Builder Gel V1 and V2?
V1 (original) has a thinner viscosity that requires the flip-technique to set the curve and suits experienced technicians comfortable with the flip step. V2 (2024 reformulation, recommended for all booths) has a thicker rubber-base-like viscosity that self-holds the apex without the flip step, which means new technicians reach the consistent salon-tier finish in 1 week of training versus 4 to 8 weeks for V1. Both deliver the same 4-week wear at the salon-tier finish.
How does builder gel compare to acrylic for the salon extension service?
Builder gel runs lighter and more natural-feeling on the nail than acrylic, with no monomer odor at application, no chemical heat reaction during cure, and the milled-off removal that protects the natural nail plate. Acrylic remains the choice for the longest sculpted extension and the lowest per-set consumable cost. Most salons stock both: acrylic for long-extension and Pink-and-White French, builder gel for the modern natural-feel overlay and short-to-medium extension.
What's the income math on stocking gel extension at the salon?
One bottle of LAVIS Builder Gel covers 30 to 40 full-set extension services. At $45 to $60 per-set salon charge, per-bottle service revenue lands at $1,350 to $2,400. The wholesale per-bottle cost at ND ($6.50 to $14) sits at the 1-percent-of-revenue cost ratio. Stocking the full builder gel + poly gel + soft tip program lifts daily extension booking volume by 1 to 2 clients per chair, adding $50 to $150 per day in service revenue per chair.
Which gel extension products should the new salon stock first?
Start with a 3-product starter kit: LAVIS BIAB V2 Set 18 (Part 1 B01-B18) plus the LAVIS Dual Form Kit 5-shape set (Pointed Almond, Stiletto, Square, Oval, Tapered Square) plus the LAVIS Gel Base + Diamond Top + Protein Bond essentials bundle. The 3-product starter covers the first 50 to 100 builder gel extension bookings at the booth-opening client tier.

Why gel extension drives the modern salon margin tier
Gel extension covers the family of products that build length, strength, and form on the natural nail without the standard acrylic monomer chemistry: builder gel for the overlay and short-to-medium extension, poly gel for the lighter sculpted full set, soft gel tips for the no-acrylic-odor extension method, and dual form kits for the architectural sculpted finish. The salon stocking the full gel extension program captures the 15-to-20-percent annual growth in the gel-vs-acrylic shift driven by the Gen Z and Millennial client base seeking the natural-look finish, the no-odor application, and the lighter-feel wear on the nail.
ND Nails Supply ships 1,109 gel extension SKUs across LAVIS Builder Gel (the production-floor anchor line with BIAB Bottle V1 + V2, Builder Jar 30ml, and Non-Sticky Jar variants), LAVIS Poly Extension Gel V1 + V2 (30ml + 60ml sizes), Apres Gel-X soft gel extension tips, LAVIS Dual Form kits, LDS Rubber Base Gel Ver 2 Bouncy Blush, Press-On Nails, and the Base + Top Gel finish category. Price band $7 to $239.70 wholesale across the full library.

Builder gel chemistry: why the modern salon stocks it over acrylic
Builder gel combines the structural strength of acrylic with the application flexibility of gel polish. The result is the salon-tier extension service that runs at the booth without the standard acrylic-system tradeoffs:
| Factor | Standard acrylic | LAVIS Builder Gel |
|---|---|---|
| Monomer odor | Strong EMA monomer scent at application, needs salon ventilation | Odorless or very low odor at application, no salon ventilation requirement |
| Heat during cure | Chemical heat reaction during polymerization (client discomfort) | Low-heat cure under LED lamp (no client heat reaction) |
| Removal | Mechanical e-file removal that thins the natural nail plate over repeat services | Mill 2/3 then soak-off remover (faster, protects natural nail) |
| Technician training curve | High skill required (bead consistency, apex placement, set time) | LAVIS V2 self-holds the apex without flip-technique (new technicians reach salon-tier finish in 1 week) |
| Set time | 60-to-90-second polymerization at room temperature | 60-second LED cure per layer with built-in brush in the bottle |
| Wear duration | 3 to 4 weeks at the salon-tier finish | 4 weeks at the salon-tier finish |
LAVIS BIAB Bottle V1 vs V2: which variant to stock
The LAVIS Builder Gel In The Bottle (BIAB) line ships in two formulation versions. The choice depends on the booth technician skill level and the daily service volume:
- BIAB Bottle V1 (36-shade original line): thinner viscosity that requires the flip-technique to set the apex curve during cure. Suits experienced technicians comfortable with the flip step. Per-set application speed slightly higher for experienced operators.
- BIAB Bottle V2 (36-shade 2024 reformulation, recommended for all booths): thicker rubber-base-like viscosity that self-holds the apex without the flip step. New technicians reach the consistent salon-tier finish in 1 week of training versus 4 to 8 weeks for V1. The V2 is the recommended starter pick for the new booth and the multi-chair salon training new staff.
- BIAB Bottle V1 + V2 Set 72 Colors: combines both lines in one 72-shade bulk box for the salon stocking the full BIAB library. Available at the bulk-save pricing tier in the buy-in-bulk category.
The 10-step LAVIS BIAB application workflow
- Prep: manicure the nail, push back the cuticle, lightly buff the natural nail plate, dust off thoroughly.
- Protein Bond and Primer: remove oil residue and condition the nail, no cure required.
- Base Gel: one thin layer, cure 60 seconds under the LED lamp.
- Framing layer (no cure): apply Builder Gel as a thin framing layer, do not cure yet.
- Apply Builder at apex: place gel at the apex (middle of the nail), push toward the cuticle line, draw the brush across the nail surface.
- Set the curve: V1 use the flip-technique to set the apex; V2 hold flat and the gel self-holds the apex curve.
- Mini cure: cure 3 to 5 seconds per finger to lock the position.
- Full cure: cure 60 to 90 seconds for the full hand under the LED lamp.
- Dual Form (if extending): apply the Dual Form, check the underside seal, cure, remove the form, refine shape.
- Finish: apply color polish, then Diamond Top, cure to seal the finish.
The fill or refill workflow runs the same steps from Step 3 onward: mill the soak-off layer of old color, keep the builder gel foundation intact, file the shape, Protein Bond, then continue from the base gel step. Refill is the steadiest recurring revenue source at the salon-tier booth.
Salon income math on the gel extension program
The gel extension program at the salon runs on the per-bottle service-revenue ratio. One bottle of LAVIS Builder Gel covers 30 to 40 full-set extension services. At the typical $45 to $60 per-set salon charge, the per-bottle service revenue lands at $1,350 to $2,400. The wholesale per-bottle cost at ND ($6.50 to $14) sits at the 1-percent-of-revenue cost ratio, which is the strongest cost-to-revenue margin on any consumable on the salon menu.
Stocking the full builder gel + poly gel + soft tip program at the booth lifts daily extension booking volume by 1 to 2 clients per chair, adding $50 to $150 per day in service revenue per chair. The multi-chair salon stocking the full program at the booth-anchor tier captures $300 to $500 in additional monthly revenue per chair from the extension service line alone.
