Frequently asked questions about HEMA-Free Gel
What does HEMA-free and TPO-free mean?
HEMA (2-hydroxyethyl methacrylate) is a gel monomer and TPO (trimethylbenzoyl-diphenylphosphine oxide) is a photoinitiator. Both started showing up in client allergic-reaction reports through the late 2010s, and the European Union added HEMA to its regulated cosmetic ingredient list in 2020. HEMA-free and TPO-free reformulations remove those trigger compounds while keeping cure speed and wear durability.
Are HEMA-free gels less durable than standard gels?
No. Wear durability matches standard gel polish. OPI Intelli, Kiara Sky Gel Pro, Lavis Deluxe Gel, A'DOR, DND HEMA & TPO Free, and LDS Color Craze all hold the 2 to 3 week wear standard with the same aftercare: cuticle oil daily, gloves for household cleaning, and a 10-minute acetone foil soak-off at week 3 instead of peeling.
Which brand should I pick for HEMA-free gel?
Match the brand to your price tier. OPI Intelli (30-second LED cure) and Kiara Sky Gel Pro lead the premium tier. The LAVIS HEMA-free lines, priced in the house-brand value tier, give the broadest coverage for high-volume salons, including Deluxe Gel, Cat Eye Ver 2, Builder Gel V2, Poly Extension, and Reflective. A'DOR is the only brand at ND whose entire catalog is HEMA-free. DND HEMA & TPO Free and LDS Color Craze let salons already on DND or LDS add HEMA-free shades with the same base and top.
Do HEMA-free gels need a different lamp?
No. Every HEMA-free brand on this page cures under a standard 48W LED salon lamp. Cure times run 30 seconds for OPI Intelli, 30 to 60 seconds for Kiara Sky Gel Pro, and 60 seconds for Lavis, A'DOR, DND, and LDS. The one rule that matters is base compatibility: stay within the same brand family for base, color, and top to avoid adhesion problems.
How should I move a client from standard gel to HEMA-free?
Do a single-finger patch test 48 hours before the full service, since most reactions show up within 24 to 48 hours of skin contact with the cured film. If the client already reacted, switch them to OPI Intelli or LDS Color Craze in the same shade family. For a whole-salon conversion, run the HEMA-free line side by side with the brand you already stock and phase out the standard line over 6 to 12 months.
Why HEMA-free matters now
HEMA (2-hydroxyethyl methacrylate) and TPO (trimethylbenzoyl-diphenylphosphine oxide) are the gel polish monomer and photoinitiator that started showing up in client allergic-reaction reports through the late 2010s. The European Union added HEMA to its regulated cosmetic ingredient list in 2020. Modern HEMA-free and TPO-free reformulations remove the trigger compounds without sacrificing cure speed or wear durability. ND carries 3,108 HEMA-free and TPO-free gel SKUs from five brand families at wholesale prices, with same-day dispatch on in-stock orders before 2pm PT and free shipping on every order of $100 or more.

The HEMA-free brands at ND
Five brand families lead the HEMA-free category at ND. Each brand designed its HEMA-free line for a slightly different salon use case:
OPI Intelli
The premium HEMA-free reformulation of the OPI GelColor line. Cures in 30 seconds LED, the fastest cure time in this category. Every new Intelli shade is HEMA-free and TPO-free by design. 175+ shades, the premium price tier on this page. Best for premium-positioned salons.
Kiara Sky Gel Pro
Modern premium with clean-beauty positioning. 176+ HEMA-free shades. Compatible with all 48W LED lamps, priced in the same premium tier as OPI Intelli. Strong choice for salons targeting health-conscious clientele.
Lavis HEMA Free lines
ND's house brand HEMA-free coverage: Deluxe Gel, Cat Eye Ver 2, Builder Gel V2, Poly Extension, and Reflective. The house-brand value tier in the HEMA-free category alongside LDS Color Craze and A'DOR. Best for high-volume salons that need broad HEMA-free coverage without premium pricing.
A'DOR
HEMA-free specialist. The entire A'DOR catalog is HEMA-free by design. Color Me Gel-ous Collection covers nudes, pastels, neons, jellies, and chrome, priced in the house-brand value tier. Best for salons running a dedicated clean-beauty service tier.
DND HEMA & TPO Free
DND's HEMA-free dedicated line, separate from the standard DND catalog. Shares compatible base and top with the original DND family, and is sold as gel and lacquer duos in the mid tier. Strong choice for salons that already stock DND and want HEMA-free coverage in the same brand family.
LDS Color Craze (Healthy)
LDS's HEMA-free and TPO-free reformulation. Same shade-family breadth as LDS Gel Polish, same cure time, same durability, and the lowest single-bottle price on this page. Best for high-volume salons wanting LDS pricing on HEMA-free formula.
How to pick the right HEMA-free brand
Match the HEMA-free brand to the client compliance ask and the salon price tier:
- Existing client allergic reaction: switch the affected client to OPI Intelli or LDS Color Craze in the same shade family. Both are HEMA-free + TPO-free, the safest reformulation across the category.
- Whole-salon HEMA-free conversion: lead with Lavis Deluxe Gel or LDS Color Craze for wholesale-priced full library coverage. Use OPI Intelli or Kiara Sky Gel Pro as the premium upsell tier.
- Clean-beauty positioned salon: A'DOR is the only brand at ND with the entire catalog HEMA-free by design. Strong marketing claim for client communications.
- Existing DND-stocked salon: add DND HEMA & TPO Free in the matching shade families. Same base + top system, no new component inventory needed.
- Specialty service salon (extensions, builder gel, cat eye): Lavis HEMA-free covers all four specialty categories at the lowest price tier. Builder Gel V2, Cat Eye Ver 2, Poly Extension, and Reflective lines.

How to apply HEMA-free gel
HEMA-free application follows the standard gel workflow. The only meaningful difference is the brand-specific base coat compatibility: stay within the same brand family for base, color, and top to avoid adhesion issues.
- Prep the nail. Push cuticles, lightly buff, dehydrate with the brand's matched nail prep. Skip this step and lifting risk goes up dramatically.
- Apply HEMA-free Base Gel. Use the matching base from the same brand family. Cure per brand spec under LED.
- Apply color coat 1. Thin even layer cuticle to free edge. Cure under LED.
- Apply color coat 2. Build to opacity. Cure again.
- Apply HEMA-free Top Gel. Seal with one coat, cap the free edge. Cure 60 seconds LED.
- Wipe or no-wipe. Most modern HEMA-free top systems are no-wipe. Some require alcohol wipe to remove tacky layer.
Care & maintenance for clients
HEMA-free wear durability matches standard gel polish. The care guidance for clients is identical to the standard gel protocol:
- Cuticle oil daily. Hydrated cuticles reduce lifting at the proximal nail fold. Single biggest contributor to 3-week wear.
- Glove for cleaning. Bleach, ammonia, and acetone household cleaners attack the cured gel film. Most premature wear traces here.
- Book removal at week 3. Peeling off gel pulls the natural nail layer. Soak-off with 100 percent acetone wrapped in foil for 10 minutes is the only safe method.
For salon storage, keep HEMA-free bottles upright, room temperature, light-protected. The TPO-free photoinitiator chemistry is more stable than the older TPO-based formulas, but direct sunlight still degrades pigment over 6+ months.
Who a HEMA-free chart is really for
- The client who has reacted. Redness, itching, or small blisters around the nail after a gel service are the pattern, and the reaction tends to build with repeated exposure rather than appear once. She is moved to a HEMA-free line in the same shade family and patch-tested before the full set.
- The technician. The person with the highest exposure is not the client; it is the tech who handles uncured gel all day, every day. A salon that switches its house chart to a HEMA-free line is protecting its own staff first, which is the argument owners find most persuasive.
- The clean-beauty client. A growing share of clients ask what is in the bottle before the service. A HEMA-free and TPO-free answer keeps that client, and A'DOR's whole catalog was built for her.
- The salon that wants one answer for everyone. Running the entire color wall HEMA-free (LAVIS Deluxe, LDS Color Craze, A'DOR, or a mix) removes the question at the desk; the standard lines stay only for a specific shade a client brings in.
A'DOR: the specialist line, and what ships with it
A'DOR is the one brand on this page whose gel catalog is HEMA-free and TPO-free throughout rather than as a sub-line, and at ND it is sold as singles in 0.6 oz bottles and as the 144-color set for the salon converting a full wall. The full set is the order A'DOR salons place first, because a whole chart in one box is simpler to swatch and to sell than a single-bottle conversion spread over months. The same brand carries the nail art that pairs with the chart: Wave Gel (sealed under Diamond Top, without which the wave effect fades), Crack Gel over a gold or silver base, Mirror Spider Gel for drawn lines, and the Metallic Marble Inks, so a salon can build an art menu around the chart without switching brands mid-service.
Switching a wall without losing clients
The conversions that work run the two lines side by side for a few months rather than swapping overnight. The salon buys the HEMA-free equivalents of its twenty most-used shades first (nudes, a French white, a classic red, the current season's two or three), swatches them beside the originals, and books sensitive clients on the new bottles while everyone else keeps their usual shade. As the standard bottles run out they are replaced by the HEMA-free number, and within a season the wall has turned over without any client noticing a change in color, cure time, or wear. Base and top are switched at the same time and kept within the brand, since the adhesion of a HEMA-free color depends on its own base.
Wholesale pricing at ND
ND offers HEMA-free gel at wholesale pricing across all five brand families. No business license required, no minimum order, no membership fee. The Buy in Bulk & Save pages add volume tiers on top of the wholesale price. Free shipping on every order of $100 or more, same-day dispatch on in-stock HEMA-free SKUs ordered before 2pm PT weekdays.
Salons converting to a full HEMA-free service tier typically start with the brand they already stock (DND or LDS or Lavis) and add the HEMA-free line side-by-side, then phase out the standard line over 6 to 12 months.
