DND HEMA & TPO Free Gel Duo 171 Secret Ingredients
Couldn't load pickup availability
DND 171 Secret Ingredients is a grey lilac from DND's HEMA & TPO Free line. You get the gel polish and its matching lacquer, so a gel manicure and a lacquer pedicure come out the same colour.
What you get
- 1 x DND 171 Secret Ingredients gel polish, 0.5 fl oz (15 mL), cured under an LED or UV lamp
- 1 x DND 171 Secret Ingredients nail lacquer, 0.5 fl oz (15 mL), air-dries
Why techs stock it
- Made without HEMA: HEMA is the ingredient most linked to gel polish allergies, and this line leaves it out.
- Fits your current system: DND says it works with any DND, DC or DIVA base and top gel.
- Standard bottle: each bottle holds 0.5 fl oz (15 mL).
- Opaque in two coats: a cream finish covers the nail in two thin coats.

Which option to choose
Compared with a standard DND duo, DND 171 Secret Ingredients swaps in a formula without HEMA or TPO while keeping the same gel and lacquer format. It still works with the DND, DC and DIVA base and top gels you already stock.
Restocking
Every DND shade has a fixed number, so write 171 on the client card. When the bottle runs low, the reorder is one code.

Frequently Asked Questions
Does the lacquer match the gel exactly?+
Yes. DND mixes DND 171 Secret Ingredients as a gel and a lacquer with the same shade number, so a gel manicure and a lacquer pedicure match. The lacquer air-dries, the gel needs an LED or UV lamp.
What do HEMA free and TPO free mean?+
HEMA is a monomer and the ingredient most linked to allergic reactions from gel polish. TPO is a photoinitiator the EU removed from cosmetics in 2025. This DND line is made without either one.
What colour is Secret Ingredients?+
DND 171 Secret Ingredients is a grey lilac. Screens show colour differently, so check a swatch stick against the client's skin before the full set.
How long do I cure each coat?+
Under an LED lamp, cure each thin colour coat 45 seconds; a UV lamp takes about 2 minutes. Thin coats cure all the way through, thick ones do not.
