Frequently asked questions
What is a HEMA-free gel polish, and why is it important for nail salons?
HEMA (2-hydroxyethyl methacrylate) is a common monomer used in standard gel formulations to aid adhesion and curing. However, it is also a well-documented skin sensitizer that can cause contact dermatitis, redness, itching, and swelling upon skin contact. A'DOR is a HEMA-free gel polish line, meaning it completely eliminates this ingredient. This makes it crucial for salons looking to offer clean beauty services, accommodate clients with allergies, and protect nail technicians who work with gel polish daily.
Does the A'DOR HEMA-Free Gel Color line require a specific base and top coat?
Yes, we highly recommend using A'DOR's own HEMA-free and TPO-free base coat and top coat. Gel chemistry relies on precise bonding between the base, color, and top layers. Mixing brands can result in poor adhesion, lifting, or mismatched curing times under the LED lamp. Additionally, if you use a HEMA-containing base coat under a HEMA-free color coat, you lose the safety and anti-allergen benefits of the HEMA-free system. Note that the Wave Gel collection specifically requires A'DOR Diamond Top to anchor the marble wave effect.
How long do HEMA-free gels last compared to traditional gel manicures?
A'DOR HEMA-free gels offer the same professional durability and longevity as traditional gel polishes. When applied correctly with proper nail plate prep, base coat, and top coat, the manicure will remain high-gloss, flexible, and free from chipping or lifting for three to four weeks. The removal of HEMA and TPO does not compromise the strength or elasticity of the cured gel film.
What is TPO, and why is the A'DOR gel line formulated without it?
TPO (diphenyl phosphine oxide) is a photoinitiator commonly used in UV/LED gel polishes to trigger the curing process under the lamp. However, regulatory bodies like the European Union have classified TPO as a potential skin sensitizer and eye irritant. A'DOR is formulated to be both HEMA-free and TPO-free, replacing both reactive ingredients with modern, safer alternatives. This provides the highest level of skin and eye protection currently available in the professional gel market.
How do A'DOR Wave Gels and Crack Gels work to create specialty nail art?
A'DOR Wave Gels are formulated to self-disperse upon application. When painted over a base color, the pigment naturally spreads to create organic, stone-like wave patterns before curing. Crack Gels are air-dry cracking formulas that shrink as they dry to create a textured, eggshell crackle effect. For the best visual results, apply A'DOR Crack Gel over a cured metallic gold or silver gel base, let the crack pattern form, cure for 60 seconds, and seal with a top coat.
Why Salons Choose A'DOR Gels
Stocking high-quality, safe, and versatile gel products is critical for modern salon success. A'DOR has established itself as a leading brand at ND Nails Supply, specializing in HEMA-free and TPO-free gel systems that cater directly to health-conscious clients and professional nail technicians. With chemical allergies on the rise in the beauty industry, transitioning to clean gel formulas is a powerful way for salons to protect their staff and differentiate their services.
The entire A'DOR catalog is formulated without HEMA (hydroxyethyl methacrylate) and TPO (diphenyl phosphine oxide). These two ingredients are the most common culprits behind skin contact allergies and eye irritations associated with traditional gel polishes. By replacing these reactive monomers with safer alternatives, A'DOR minimizes the risk of redness, itching, and swelling for both clients and technicians who handle gel products daily. Salons face growing demand for clean beauty options. Clients who are sensitive to standard cosmetic chemicals or have histories of skin irritation actively search for salons that advertise HEMA-free services. By stocking A'DOR, you can capture this premium niche and charge a higher service tier fee. Nail professionals who spend eight or more hours a day exposing their skin to uncured gel also benefit from the safety of this clean formula.
A'DOR gel systems offer identical durability and finish quality to standard gels. The HEMA-free formula cures to a high-gloss, flexible layer that resists chipping for three to four weeks. Additionally, because this line is a first-mover in the dedicated HEMA-free market in the United States, stocking it gives your salon an edge over competitors who rely on traditional brands.

A'DOR Crack Gels
The A'DOR Crack Gel Collection shrinks as it cures to mimic a natural eggshell or cracked leather texture. This formula works best when layered over a cured metallic gold or silver gel base, creating a high-contrast vintage effect that cures in 60 seconds.

Step-by-Step Application Guide for A'DOR Gels
Applying A'DOR HEMA-free gels requires clean technique to prevent contamination with standard gel residues. Follow this professional workflow:
- Prepare the Nail Surface: Sanitize the hands, push back the cuticles, and gently remove the shine from the natural nail using a 240-grit buffer. Dehydrate the plate with a clean nail prep solution.
- Apply the Base Coat: Brush a thin, even layer of HEMA-free base gel over the nail. Cap the free edge to prevent shrinkage. Cure for 60 seconds under a professional LED lamp.
- Apply the Color Layer: Apply the first thin coat of A'DOR Gel Color. Cure for 60 seconds. Repeat with a second thin layer to achieve full opacity, and cure again.
- Create Wave Effects: If using A'DOR Wave Gel, apply a base color and cure. Paint a layer of Wave Gel, then apply drops of accent color. Allow the pattern to disperse for 5 seconds, then cure. Apply a layer of Diamond Top and cure.
- Create Crack Effects: Apply a gold or silver metallic gel base and cure. Brush a thin layer of Crack Gel over the cured metallic base. Watch the cracking pattern develop as the gel air-dries, then cure for 60 seconds. Seal with top gel and cure.
- Finish and Protect: Wipe away any sticky residue if using a wipe top coat, then apply cuticle oil to the surrounding skin.
Note: For clients moving from standard gel to HEMA-free, do a single-finger patch test 48 hours before the full manicure service. Most allergic reactions show up within 24 to 48 hours of skin contact with the cured film.
Caring for HEMA-Free Manicures
HEMA-free gels maintain their durability when protected from harsh chemicals. Advise clients to wear protective gloves when using household cleaners, dish soaps, or solvents, as these chemicals can degrade the cured gel surface over time. Daily application of high-quality cuticle oil is also essential. Hydrated skin at the proximal nail fold prevents lifting and maintains the seal at the base of the nail.
For salon storage, store all A'DOR gel bottles upright in a cool, dark place. The chemical initiator package in HEMA-free formulas is sensitive to ambient UV light and temperature fluctuations. Ensure bottles are sealed tightly after use, and keep them away from active curing lamps or sunny windows to prevent premature thickening.
