The Healthy Nails Collaborative Professional Nail Safety Standard

 

The Healthy Nails Collaborative developed the HNC Professional Nail Safety Standard to address long-standing gaps in transparency and safety communication within the nail industry.

 

Professional nail products are based on polymer chemistry, photoinitiator systems, and controlled curing processes. Despite decades of available research, the industry has historically lacked a consistent framework for communicating product chemistry, curing requirements, and responsible safety practices.

 

The HNC Professional Nail Safety Standard establishes a clear structure for brands that wish to demonstrate transparency and alignment with established scientific understanding of professional nail products.

 

Brands that meet the requirements of this standard may apply for HNC Brand Verification and display the HNC Verified Seal.

 

Verification confirms that a brand has provided documentation showing alignment with the safety principles outlined below.

 

Applications for brand verification will begin April 2026.

​

​

The HNC Professional Nail Safety Standard

 

The HNC Professional Nail Safety Standard focuses on four core areas of responsibility within the professional nail product industry.  These standards exist to promote transparency, responsible education, and safer professional practices.

 

1. Product Transparency

 

Verified brands must demonstrate transparency regarding the composition and safe use of their products.

Requirements include:

 

a.  Providing accurate Safety Data Sheets (SDS) for professional products

b.  Maintaining accessible safety documentation for professional reference

c.   Avoiding misleading or scientifically inaccurate chemical claims

e.   Ensuring product usage do not contradict established polymer science

​​

2. Lamp Compatibility and Curing Guidance

 

Professional nail coatings rely on photopolymerization, a curing process dependent on specific light wavelengths and photoinitiator systems.  Curing chemistry varies between formulations, therefore, responsible communication regarding curing systems is required.

Requirements include:

 

a.   Providing clear curing guidance for professional use

b.   Public statement regarding the testing used to establish lamp, compatibility, and caring guidance for all products.

c.   Avoiding claims that imply universal curing compatibility because scientific evidence does not support it

d.   Ensuring educational materials reflect current polymer science regarding curing systems

 

3. Responsible Marketing Practices

 

The HNC Professional Nail Safety Standard requires marketing claims to reflect scientifically supported information rather than misleading or exaggerated safety statements.

Requirements include:

 

a.   Avoiding marketing language that misrepresents product safety

b.   Avoiding claims that contradict established chemistry or safety guidance

c.   Avoiding statements that dismiss legitimate safety concerns related to professional nail products

d.   Ensuring marketing materials do not promote unsafe application practices

e.   Avoiding demonstrations or promotional content that show direct skin to contact with uncured nail products.

f.    Prromote appropriate protective practices, including the use of gloves when handling uncured nail chemistry

 

4. Professional Education Responsibility

 

Professional nail products are used within a licensed trade that relies on proper education and responsible handling.  Brands seeking verification must demonstrate that their educational materials support safe professional practices.

Requirements include:

 

a.   Providing accurate guidance for product use

b.   Avoiding demonstrations that promote unsafe exposure to uncured product

c.   Encouraging correct curing practices and exposure control

d.   Supporting professional awareness of allergic reactions related to uncured nail products and no claims that contradict establish polymer science or occupational safety guidance.

e.   Advocate for use of PPE such as gloves.

​​

HNC Brand Verification

 

Brands that meet the requirements of the HNC Professional Nail Safety Standard may apply for HNC Brand Verification.  Verification confirms that a brand has submitted documentation demonstrating alignment with the HNC Professional Nail Safety Standard.

 

Brands that successfully complete verification may display the HNC Verified Seal, indicating that the company has demonstrated transparency and responsibility in relation to the HNC Professional Nail Safety Standard.

 

Verification indicates alignment with the standard but does not constitute product endorsement.

​​​

Compliance, Review, and Renewal

 

HNC Brand Verification is not permanent.

 

Verification confirms that a brand met the requirements of the HNC Professional Nail Safety Standard at the time of review. Because product formulations, curing instructions, and marketing practices may change over time, verification requires ongoing alignment with the standard.

 

Verified brands agree to the following conditions:

 

• Verification is valid for one year from the date of approval

• Brands must submit documentation during annual renewal review

• Marketing claims must remain consistent with the HNC Professional Nail Safety Standard

 

The Healthy Nails Collaborative reserves the right to review, suspend, or revoke verification if a brand no longer aligns with the requirements of the standard.

 

If verification is revoked, the brand must immediately remove the HNC Verified Seal from packaging, websites, and marketing materials.

 

The Healthy Nails Collaborative will publicly list brands that have applied for verification and are currently under review, along with brands that have successfully completed the verification process. In the interest of transparency, we will also acknowledge when formal complaints or concerns have been submitted for review. Our goal is not to shame brands, but to give professionals and consumers a clear view of which companies are actively engaging with safety standards and which issues are being evaluated. Verification, applications in progress, and ongoing reviews will all be visible so the industry can see who is participating in raising the standard.

​

Application Process

 

Beginning April 2026, brands may submit applications for HNC Brand Verification.

 

Applications will require documentation related to:

 

• Product SDS documentation

• A public statement describing the testing used to establish lamp compatibility and curing guidance for all products.

• Educational materials as requested by inc if applicable.

​

 

Applications will be reviewed by the Healthy Nails Collaborative to determine alignment with the HNC Professional Nail Safety Standard.

​​

Public Registry

 

Brands that successfully complete verification will be listed in the HNC Verified Brand Registry, a publicly accessible directory of companies that have demonstrated alignment with the HNC Professional Nail Safety Standard.

 

The registry will include:

 

• Brand name

• Verification date

• Renewal status

• Verification status

 

This registry allows professionals and consumers to see which brands have chosen to participate in transparent safety standards.

​​

Transparency

 

The purpose of the HNC Professional Nail Safety Standard is not to endorse products.  Its purpose is to promote transparency, responsible education, and alignment with established nail chemistry and safety science within the professional nail industry.

​

The Healthy Nails Collaborative will invite nail product brands to participate in the HNC Brand Verification program. Brands that apply will appear in the public registry as either Under Review or Verified once the process is complete. In the interest of transparency, brands that formally decline the invitation may also be noted as having declined participation. The registry is intended to give professionals and consumers a clear view of which companies are engaging with the verification process and supporting higher safety and transparency standards within the nail industry.
