Frequently asked questions about OPI
What is the difference between OPI GelColor Intelli and OPI Infinite Shine?
GelColor Intelli is the cure-required gel line. It is HEMA-free and TPO-free, cures in 30 seconds under LED, and wears up to 3 weeks. Infinite Shine is OPI's air-dry gel-effect lacquer line (no lamp, 7 to 11 day wear); it is not currently listed at ND, where the lamp-free OPI service is the classic Nail Lacquer in the same codes as the gel.
Are OPI gel products HEMA-free?
The Intelli line is. Every new GelColor Intelli shade is formulated HEMA-free and TPO-free, and OPI is steering all new shade development into Intelli. The original GelColor classic line still contains HEMA, so salons with allergy-report clients should switch those clients to the Intelli version of the same shade family. Powder Perfection dip uses no HEMA monomer either.
Can I match OPI Gel with OPI Nail Lacquer in the same shade?
Yes. Most OPI shades ship in both Gel and Lacquer formats, and many also exist in Powder Perfection. For mani-pedi matching, use the gel on fingers and the lacquer on toes, then let the client see the same shade name in both bottles. The Gel & Lacquer Duo category at ND lists the pre-paired sets so you do not have to hunt for the match.
Do I need a specific lamp for OPI gel curing?
No. OPI gel cures under standard 48W salon LED lamps. Intelli cures 30 seconds per coat and the Intelli Top is no-wipe. Classic GelColor cures 30 to 60 seconds per coat and its top coat needs an alcohol wipe. Use the matching base: Intelli Base for Intelli and ProStay Base for classic, cured 30 seconds LED, then two thin color coats and one top coat with the free edge capped.
Does OPI offer wholesale pricing?
Yes. ND Nails Supply sells the full 1,582-SKU OPI catalog at wholesale pricing for everyone, with no business license, no minimum order, and no membership fee. Orders of $100 or more ship free, and in-stock OPI ordered before 2pm PT on weekdays leaves the same day. The Buy in Bulk & Save category adds another 10 to 25 percent volume discount on orders of 50 or more bottles.
Why OPI is the icon
OPI was founded in 1981 in North Hollywood, California, and built the global gel polish category from the ground up. The shade-naming convention (Lincoln Park After Dark, Bubble Bath, You're Such a BudaPest) became salon shorthand long before the product diversification of the modern catalog. Today OPI runs four parallel systems at ND Nails Supply: GelColor Intelli (the new HEMA-free reformulation), GelColor classic, Nail Lacquer, and Powder Perfection dipping powder. Salons that stock OPI lead with premium positioning toward clients who already recognize the brand.
ND carries the full 1,582-SKU OPI catalog at wholesale pricing, with same-day dispatch on in-stock orders before 2pm PT and free shipping on every order of $100 or more. No business license, no minimum order. For salons running OPI as the flagship brand, the Buy in Bulk & Save category at ND adds another 10 to 25 percent discount on volume orders.
The OPI product systems
OPI's modern catalog runs four product systems, each engineered for a different salon workflow:
OPI GelColor Intelli
The new HEMA-free and TPO-free reformulation. Cures in 30 seconds under LED, designed for sensitive-client compliance and faster service throughput. This is the system OPI is steering all new shade development into. 175+ shades and growing.
OPI GelColor (classic)
The original cure-required gel line, contains HEMA. Cures 30 to 60 seconds under LED. Still the foundation library with 300+ shades that have not yet migrated to the Intelli reformulation. Salons that built their inventory before Intelli launched usually maintain mixed stock.
OPI Infinite Shine
OPI's air-dry gel-effect lacquer system, no lamp needed, up to 11 days of wear. It is not currently listed at ND; the lamp-free OPI service here is the classic Nail Lacquer line, which shares its codes with GelColor Intelli and Powder Perfection for the mani-pedi match.
OPI Powder Perfection (Dipping)
OPI's entry into the dipping powder category. Strong shade coordination with the gel and lacquer lines. The Pink & White system covers the French/American manicure use case. The Powder Perfection essentials kit is the starter purchase for salons adding dip services.
How to pick the right OPI system
Use-case decision tree for matching OPI line to salon workflow:
- Salon prioritizing HEMA-free compliance: lead with GelColor Intelli. Every new Intelli shade is HEMA-free and TPO-free, the safest starting point for modern client expectations.
- Salon with existing OPI inventory: maintain GelColor classic for existing client favorites, gradually replace top sellers with Intelli versions as they release.
- Clients who avoid lamp services: stock OPI Nail Lacquer in the same codes as the gel wall, with a base and top and a top-coat refresh at home for a full week of wear.
- Dip-curious salon: start with Powder Perfection essentials kit plus 12 to 20 colors aligned to your top GelColor sellers. Cross-sell becomes natural at checkout.
- Mani-pedi matching service: focus on codes available across GelColor Intelli, Nail Lacquer, and Powder Perfection. Buy in the OPI Gel & Lacquer Duo category for pre-paired sets.

How to apply OPI gel
OPI gel application follows the standard 5-coat workflow. The Intelli system shaves 30 seconds off cure time per coat, which adds up across a full service.
- Prep the nail. Push cuticles, lightly buff the surface, dehydrate with OPI Pro Bonder. Skip this and lifting risk climbs.
- Apply OPI Base Coat. Use the matching base (Intelli Base for Intelli, ProStay Base for classic). Cure 30 seconds LED.
- Apply color coat 1. Thin even layer cuticle to free edge. Cure 30 seconds (Intelli) or 60 seconds (classic) LED.
- Apply color coat 2. Build to opacity. Most OPI shades reach full coverage at 2 coats. Cure again.
- Apply OPI Top Coat. Seal with one coat, cap the free edge. Cure 60 seconds LED.
- Final wipe or not. Intelli Top is no-wipe. Classic Top requires alcohol wipe.
Care & maintenance for clients
OPI client retention runs on consistent wear performance. The three rules to share at checkout extend the salon's service value:
- Daily cuticle oil. Hydrated cuticles reduce gel lifting at the proximal nail. Recommend the salon's preferred cuticle oil for client home stock.
- Glove for cleaning. Bleach, ammonia, and acetone-based household cleaners attack the gel film. Most premature wear shows up here.
- Book removal at week 3. Peeling off gel pulls the natural nail layer. 100 percent acetone soak with foil wrap for 10 minutes is the only safe removal.
For salon storage, keep OPI bottles upright at room temperature in light-protected drawers. Direct sunlight degrades pigment depth over 6+ months.
What the OPI catalog at ND is made of
| Line | What it is | How it is sold |
|---|---|---|
| GelColor Intelli | The current OPI gel: HEMA-free and TPO-free, 30-second LED cure | Singles by code, 6 and 12-color seasonal sets, and the Intelli-Gel starter kits and combo sets |
| Nail Lacquer | The classic air-dry lacquer, the largest single group on this page | Singles by code and seasonal 6 and 12-color sets |
| Gel and Lacquer duos | Intelli gel and Nail Lacquer of one code paired | Singles and seasonal duo sets |
| Powder Perfection | OPI dip powder in 1.5 oz jars | Singles by code, the pink and white kits, and seasonal sets |
| Intelli 3-in-1 | Powder, gel, and lacquer of one code in one listing | Singles and 6 and 12-color sets |
| Base, top, and prep | Intelli base and top, Bond Aid, Nail Envy treatments | Singles |
The thread through all of it is the code: S86 Bubble Bath is S86 in every format OPI makes it in, which is what makes a mani-pedi match, a dip-to-gel refill, and a retail lacquer sale the same conversation at the desk.
Reading an OPI code
A permanent OPI shade carries a letter and two digits (N25 Big Apple Red, S86 Bubble Bath, H22 Funny Bunny, L00 Alpine Snow), where the letter marks the collection the shade was born in and the number its position; those codes stay in production year after year and are the ones to build a wall on. A seasonal shade carries a season letter and three digits (F037 to F048 for the Fall 2026 Most Requested collection, S073 to S084 for Summer 2026), is produced for its season, and is bought as the set while it is in stock if a salon wants it on the chart afterward. The same code is on the gel, the lacquer, and the dip jar of that shade, so the salon reorders by code rather than by name, and the client who asks for "the Bubble Bath" is served from whichever format the service calls for.
Where OPI sits on a mixed wall
OPI is the brand clients know by name, and at ND it is the premium tier beside the house lines. Salons that run both give OPI the shades that get asked for by name (Big Apple Red, Bubble Bath, Funny Bunny, Lincoln Park After Dark, Alpine Snow, the current seasonal drop) and the clients who want the brand on the bottle, and give LAVIS and LDS the everyday nudes and pinks where the per-bottle price matters and nobody asks for a name. Because ND is a wholesale-for-everyone supplier, the OPI premium is in the bottle, not in a professional markup, and a salon that mixes the tiers quotes the OPI service above the house-brand service on the menu, with the same base, top, and lamp routine at the station.
Wholesale pricing at ND
ND offers OPI at wholesale pricing for everyone. No business license required, no minimum order, no membership fee. The OPI Buy in Bulk page adds set listings on the wholesale tier for orders of 50+ bottles. Free shipping on every order of $100 or more, same-day dispatch on in-stock OPI ordered before 2pm PT on weekdays.
Salons that anchor on OPI as the premium brand typically pair it with LDS or Lavis for value-tier coverage on price-sensitive shade families. The matching mani-pedi service tier sells better when clients see the OPI shade in both the gel and the lacquer on the salon's shade chart.
