Frequently asked questions about OPI
What is the difference between OPI Intelli Gel and OPI Infinite Shine?
Intelli Gel is the cure-required gel line (LED 30 seconds, UV 2 minutes) for long-wear salon use. Infinite Shine is the air-dry gel-effect lacquer line, no lamp needed, lasts up to 11 days. Both share the iconic OPI shade library.
Are OPI gel products HEMA-free?
Yes. OPI Intelli Gel is HEMA-free and TPO-free, designed for sensitive clients and modern compliance standards. The original GelColor line contains HEMA.
Can I match OPI Gel with OPI Nail Lacquer in the same shade?
Most OPI shades come in both Gel and Lacquer formats. Use the Gel & Lacquer Duo category to find pre-paired matching sets for manicure and pedicure consistency.
Do I need a specific lamp for OPI gel curing?
OPI gel products cure under standard salon LED lamps (48W is the typical size). Intelli Gel cures in 30 to 60 seconds per coat under LED.
Does OPI offer wholesale pricing?
Yes. ND Nails Supply offers wholesale pricing on all OPI products, no minimum order, no business license required. Check the Buy in Bulk category for additional volume discounts.
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 over $99. 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
Air-dry gel-effect lacquer system. No lamp needed, lasts up to 11 days. Used as the alternative service tier for clients who avoid UV/LED exposure or want a faster appointment with no curing breaks. Most Infinite Shine shades match a GelColor counterpart for matching mani-pedi services.
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 Infinite Shine. The air-dry chemistry hits 7 to 11 day wear, which beats traditional lacquer wear by 3x.
- 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 shades available across GelColor + Infinite Shine + Powder Perfection. Buy in the 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.
Wholesale pricing at ND
ND offers OPI at wholesale pricing for everyone. No business license required, no minimum order, no membership fee. The Buy in Bulk & Save category adds 10 to 25 percent volume discount on the wholesale tier for orders of 50+ bottles. Free shipping on every order over $99, 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 Gel and Infinite Shine on the salon's shade chart.
