Frequently asked questions
What does the DND HEMA-Free + TPO-Free Gel + Lacquer Collection cover at ND?
297 DND HEMA-Free + TPO-Free matching gel + lacquer duo SKUs organized into 7 themed Part sets: Part 01 Every Hue (universal salon shade run), Part 02 High Gloss, Part 03 Island Gal (tropical summer), Part 04 I'm The Captain Now (bold evening statement), Part 05-07 (additional seasonal and statement palettes). Each Part set covers 36 matching duos at $234 per set. Plus the DND HEMA-Free Full Line Combo Bulk at $1,800 covering 288 duos across the entire shade library.
What does HEMA-Free + TPO-Free actually mean for the client?
HEMA (Hydroxyethyl Methacrylate) is the acrylic monomer in standard gel polish that triggers contact allergy in some clients (redness around cuticle, itching, small fluid bumps). TPO (Diphenyl 2,4,6-trimethylbenzoyl phosphine oxide) is the photoinitiator that triggers skin and eye irritation in a smaller subset. DND HEMA-Free + TPO-Free uses alternate chemistry that delivers the same 3-week wear and salon-tier finish without the chemistry that drives the reactivity events. Ideal for sensitive-client salon segment and salon technicians on daily exposure.
Does HEMA-Free gel last as long as standard gel?
Yes. DND HEMA-Free holds the standard salon-tier 3-week wear, the glass-like glossy finish, and the production-floor cure time under the standard LED lamp at 36W or higher. The HEMA-Free formulation replaces the HEMA monomer with alternate methacrylate chemistry that delivers equivalent bond strength without the contact-allergy trigger. The TPO-Free photoinitiator system cures equivalently under the LED lamp.
Which DND HEMA-Free set should the new salon stock first?
Start with Part 01 Every Hue at $234. The 36-duo starter covers the universal salon-tier shade range from nudes to brights to darks, which serves the first 50 to 100 HEMA-Free service bookings at the booth-opening client tier. Add Part 02 High Gloss if the booth runs the gloss-finish service tier. Mid-volume salons add Part 03 Island Gal for summer and Part 04 I'm The Captain Now for the evening upscale-tier client.
How does the matching gel + lacquer duo workflow work?
Each DND HEMA-Free duo ships as a paired set with identical shade codes across both sides. The gel side is the HEMA-Free + TPO-Free salon-tier gel polish for the long-wear manicure (3-week wear, cures under LED lamp). The lacquer side is the air-dry polish for the pedicure or at-home retail close (5-7 day wear with base + top coat). Same shade code on both sides means exact-match nails and toes from a single product order for the sensitive-client mani-pedi booking.

Why the HEMA-Free service tier drives the sensitive-client salon margin
HEMA and TPO are the two chemistry components in standard gel polish that trigger reactivity in the sensitive-client segment of the salon market. HEMA (Hydroxyethyl Methacrylate) is the acrylic monomer that bonds the cured gel to the natural nail, and a subset of the salon-tier clientele develops contact reactivity to HEMA over repeated exposure: redness around the cuticle, itching, small fluid-filled bumps at the side wall. TPO (Diphenyl 2,4,6-trimethylbenzoyl phosphine oxide) is the photoinitiator that triggers the cure under the LED lamp, and a smaller subset reacts to TPO with eye irritation and skin sensitivity. The salon serving the sensitive-client tier stocks HEMA-Free + TPO-Free gel for the same reason the food service tier stocks gluten-free menu items: a niche but loyal client segment that pays the upscale service price for the cleaner formula.
ND Nails Supply ships 297 DND HEMA-Free + TPO-Free Gel + Lacquer matching duo SKUs covering the Part 01 through Part 07 themed 36-color sets at the $234 set tier, plus the 288-combo full-line bulk option at $1,800. The DND HEMA-Free line gives the sensitive-client salon the brand-recognition DND finish (matching gel manicure + air-dry lacquer pedicure) without the HEMA + TPO chemistry that drives the reactivity events.
What HEMA and TPO are in plain language
| Chemistry | Standard role | Reactivity profile | HEMA-Free + TPO-Free alternative |
|---|---|---|---|
| HEMA (Hydroxyethyl Methacrylate) | Acrylic monomer that bonds cured gel to the nail plate | Contact allergy in some clients: redness, itching, small fluid bumps around the cuticle. Risk grows with repeated exposure. | DND HEMA-Free replaces HEMA with alternate methacrylate chemistry that delivers the same bond strength without the contact-allergy trigger. |
| TPO (Diphenyl 2,4,6-trimethylbenzoyl phosphine oxide) | Photoinitiator that triggers the gel cure under the LED lamp | Skin and eye irritation in a subset of clients and salon technicians on daily exposure. | DND TPO-Free uses an alternate photoinitiator system that cures equivalently under the standard LED lamp without TPO. |
| Standard salon-tier benefits retained | 3-week wear, glass-like finish, salon production-floor cure time, full pigment library | None compromised in the HEMA-Free formulation | DND HEMA-Free holds the salon-tier wear performance while removing the chemistry that triggers the reactivity events. |

The matching gel + lacquer duo workflow
Each DND HEMA-Free duo ships as a paired set: the gel side for the long-wear salon manicure plus the matching shade Nail Lacquer for the air-dry pedicure side or the at-home retail sell-through. The shade codes match exactly across both formulations, which lets the salon offer the mani-pedi combo service in the identical DND shade for the sensitive-client booking.
- Gel side (DND HEMA-Free Gel): HEMA-Free + TPO-Free salon-tier gel polish, 3-week wear, cures under the standard LED lamp at 36W or higher. Salon production-floor service tier.
- Lacquer side (DND HEMA-Free Lacquer): air-dry polish, no lamp required, 5 to 7 day wear with base + top coat, ideal for the pedicure side or the at-home retail close.
- Shade-match guarantee: same shade code on both sides means the salon client gets exact-match nails and toes from a single product order.
