Key Highlights:

  • The National Advertising Division upheld some Revlon ColorSilk claims (e.g., “with a Bond Repair Complex,” anti-breakage percentages, and measured shine) but ordered discontinuation or revision of others—most notably the claim that the product “repairs hair from the inside out.”
  • NAD’s findings center on how closely marketing language must track specific evidence and how testing context (wet vs. dry hair), imagery, and shade-specific results shape reasonable consumer interpretation.
  • The decision illustrates practical steps brands must take: clearly qualify claims, disclose testing conditions and shade variability, substantiate implied repair claims with robust penetration and performance data, and ensure influencer disclosures and photographs accurately reflect results.

Introduction

A recent National Advertising Division (NAD) decision involving Revlon’s ColorSilk hair-color line draws a bright line around how far cosmetic marketers can stretch repair and performance claims. Following a competitor challenge from Henkel Corporation, NAD’s mixed ruling both validated certain performance claims and struck down or required revision of others. The case highlights the fine-grained standards that govern evidence for haircare promises—tensile strength numbers alone do not authorize sweeping claims that imply complete structural restoration.

The outcome matters beyond Revlon and Henkel. Cosmetics and personal-care marketers commonly make claims about strength, shine, smoothness, and “bond repair.” The NAD decision demonstrates that substantiation must match consumer takeaway: the exact language, imagery, and context determine whether a claim is supported. That demands not just laboratory proof but an alignment of test conditions, visuals, and disclosures.

This article unpacks the NAD ruling, explains the scientific and legal reasoning behind each finding, explores the testing methods at issue, and lays out practical takeaways for brands, retailers, and consumers. It also examines how this decision fits into broader trends in advertising scrutiny for personal-care products, and it provides concrete guidance for companies aiming to avoid similar challenges.

How the NAD Review Began and What It Covers

The National Advertising Division of BBB National Programs evaluates advertising claims when competitors or third parties request review. NAD does not issue formal legal penalties but makes recommendations that carry weight in the marketplace; advertisers typically comply to avoid escalation to the National Advertising Review Board or federal agencies.

Henkel’s challenge targeted multiple ColorSilk claims across packaging, digital marketing, retail pages, and influencer content. NAD examined the available studies and evidence submitted by both parties and assessed (1) whether the claims were supported by reliable testing, and (2) whether consumers could reasonably interpret the claims in the way Revlon presented them.

NAD’s decision followed a standard analytical framework: identify the claim and the message consumers would likely take from it; determine whether the advertiser provided adequate substantiation that matches that message; and, if not, recommend discontinuation or rewording. For claims that were technically supported but potentially misleading due to presentation or context, NAD required qualifiers or disclosures.

Two broader themes emerge from the decision. First, marketing language that implies deep structural restoration is subject to a very high evidentiary bar. Second, testing context—such as whether results were measured on wet versus dry hair, or on a particular shade—shapes what claims can reasonably say without additional qualification.

“With a Bond Repair Complex”: What the Evidence Showed and What It Means

Revlon’s claim that ColorSilk is formulated “with a Bond Repair Complex” survived NAD scrutiny. The company produced tensile strength testing and hair-penetration studies tied to specific ingredients, and NAD found that evidence provided a reasonable basis for the ingredient-focused claim.

Key points behind this finding:

  • The phrase “with a Bond Repair Complex” is primarily ingredient-descriptive rather than a promise of complete structural restoration. NAD accepted that Revlon’s testing established the presence of ingredients designed to interact with hair bonds.
  • Tensile strength testing demonstrated measurable performance changes after product application. These tests typically assess the force required to break hair fibers, and improvement in tensile strength is evidence of reduced fragility.
  • Penetration studies showed some level of ingredient ingress into the hair cortex, which supports a mechanistic claim that ingredients interact below the hair surface rather than merely depositing on the cuticle.

Why descriptive claims survive when stronger claims do not The difference between an ingredient statement and a repair promise is critical. Saying a product contains a “Bond Repair Complex” communicates formulation content and intent; it does not, alone, assert that the product will fully restore internal hair structure. NAD treats such ingredient-based claims as allowable when companies show the ingredient’s presence and a plausible mechanism of action.

Brands that position formulations this way must ensure their supporting studies legitimately demonstrate ingredient presence and plausible functionality. Documentation might include chemical analyses (e.g., HPLC, mass spectrometry confirming ingredient deposition), microscopy showing penetration, and mechanical tests showing improved strength consistent with the purported action of the ingredient.

Practical implication: A careful formulation claim—rooted in ingredient identity and mechanistic evidence—can be persuasive and defensible. The moment marketing moves beyond formulation description into broad “repairs” or “restores” language, the evidence must expand in scale and specificity.

Dissecting the “Up to 98% Less Breakage” Claim: Methodology and Comparative Evidence

Revlon’s “up to 98% less breakage” claim centered on anti-breakage studies that quantified breakage reduction relative to untreated hair or competitor products. Henkel challenged the studies, pointing to different results in its own testing and arguing that the variance undermined Revlon’s conclusion. NAD disagreed and allowed the claim to stand.

Why NAD accepted Revlon’s breakage results NAD’s assessment focused on the reliability of the study methods and whether differences between study outcomes were excessive or indicative of fundamental flaws. The organization found Revlon’s study reliable and viewed the diverging figures as plausibly attributable to methodological differences, including:

  • Testing apparatus: Devices that measure combing force or tensile strength can vary in calibration, loading rates, and sensitivity, yielding different absolute numbers even when testing the same sample.
  • Combing protocols: Differences in comb type, combing speed, hair hydration state, and combing cycles affect breakage outcomes.
  • Sample preparation and hair source: Natural variability in hair fiber diameter, prior chemical treatments, age, and ethnic origin influence results.

NAD concluded Henkel did not prove Revlon’s methods were fundamentally flawed; the differences between results did not automatically invalidate Revlon’s claim.

What “up to” means—and how it’s tested “Up to” phrasing signals a best-case outcome rather than an average. Regulatory and industry practice expects that “up to X” claims reflect real, observed maxima in testing but should not mislead consumers into expecting universal results. Brands should therefore:

  • Report the conditions under which the “up to” number was obtained (shade used, hair type, application method).
  • Avoid presenting “up to” figures as typical unless backed by representative sample testing.

For example, a tensile-strength study may report that one formulation reduced breakage by 98% under specific laboratory conditions. That result is defensible as an “up to” number if Revlon makes clear the test context or if the claim appears in proximity to the study context.

Broader consequence: When competitors run their own tests reaching different numbers, NAD will examine methodology, not simply compare top-line percentages. Disparities alone do not automatically void a claim; methodological criticism must show the testing was invalid or biased.

“Repairs Hair from the Inside Out”: Why NAD Found the Claim Overstated

NAD drew a firm line against Revlon’s claim that ColorSilk “repairs hair from the inside out.” The organization concluded the language conveyed a consumer takeaway that the product yields significant, perhaps complete, repair of the hair fiber. Revlon’s data—limited cortex penetration evidence and some mechanical improvements—fell short of supporting that implication.

How consumers interpret “inside out” Plain-language phrases such as “inside out” evoke substantial structural change. Consumers interpret such claims as indicating restoration within the cortex, the hair’s inner structure where protein bonds and lipid content determine strength and elasticity. When marketers assert “repair” that suggests remedial correction of internal damage, the claim invites expectations of recovery comparable to the hair’s undamaged state.

What the evidence must show to support deep repair claims To substantiate an “inside-out” repair claim, evidence must demonstrate meaningful reconstitution of the hair’s core properties, ideally through multiple, convergent lines of testing:

  • Rigorous penetration studies showing consistent and functionally significant ingredient delivery into the cortex across relevant hair types and shades.
  • Functional restoration metrics that go beyond modest tensile-strength changes: measures that compare pre-damage, post-damage, and post-treatment properties such as elasticity, fracture toughness, and microscopic repair of cortical disruption.
  • Clinical or consumer-use studies demonstrating sustained improvements in hair performance attributes.

Revlon provided penetration and tensile data, but NAD determined these did not support the sweeping repair message. The data showed some ingredient ingress and measurable improvements, but not the level or breadth of repair implied by “repairs hair from the inside out.”

Why the standard is high Claims that imply structural repair risk promising irreversible or comprehensive change. Regulators and self-regulatory bodies treat such promises stringently because they affect consumer expectations. If a product cannot meet that level of performance across normal variations in hair type and condition, the claim is deceptive.

Marketing takeaway: Avoid language that implies complete or deep structural restoration unless evidence is robust, replicable across conditions, and demonstrates clinically meaningful repair. Brands should prefer more measured descriptions—e.g., “helps strengthen hair,” “forms bonds to reduce breakage”—paired with clear disclosures about test conditions.

Wet vs Dry Testing: Why “Up to 94% Smoother/Silkier” Required Context

NAD accepted Revlon’s wet-combing study showing a 94.9% reduction in combing force (compared with untreated hair), thereby supporting the numeric basis for “up to 94% smoother” and “up to 94% silkier.” However, the organization objected to the claims as presented without qualification because consumers could interpret the messaging to apply to dry hair.

Testing context governs interpretation The study that produced the 94.9% figure used wet-hair combing protocols. Wet hair behaves differently from dry hair: it swells, the cuticle scales lift, and combing resistance changes dramatically. A claim anchored to wet-hair testing is not interchangeable with dry-hair outcomes.

NAD’s concern focused on imagery and presentation. If packaging or advertising includes visuals of dry hair or context that implies everyday styling conditions, consumers might take the claims to mean dry-hair improvements. Because Revlon had not submitted dry-hair performance data, NAD recommended that the claims be discontinued or modified to communicate clearly that results were measured on wet hair.

Implications for claim drafting Brands must align wording and visuals with the specific conditions under which tests were performed. Effective options include:

  • Qualifying the claim with explicit context: “Up to 94% smoother (wet combing test).”
  • Placing an asterisk and a nearby disclosure that clarifies the testing conditions and any shade or hair-type limitations.
  • Avoiding imagery that implies dry-hair benefits when testing covered only wet-hair scenarios.

Real-world consumer expectations Consumers use hair color products under everyday conditions. If marketing overstretches lab-derived performance metrics into unintended contexts, brands risk both consumer complaints and self-regulatory action. Testing that measures wet-hair performance is valuable, but it must be presented transparently.

Shine, Shade Variability, and Before/After Images: How Revlon Resolved Concerns

Revlon made voluntary revisions during the NAD proceeding that resolved several issues NAD raised about shine claims and imagery. The company clarified its “9x shinier” claim to “up to” and disclosed that testing was conducted on a Medium Brown shade, with results varying by shade. NAD accepted these changes.

Why shade matters Hair color interacts with light differently across shades. Pigment deposition, surface reflectance, and cuticle condition influence measured shine. A single-shade study can produce high shine numbers that are not representative for lighter or darker shades. Disclosing the shade used in testing prevents consumers from assuming uniform results across the entire shade range.

Before-and-after photographs and implied claims Before-and-after images can imply dramatic results. NAD evaluated Revlon’s imagery and accepted its assurances on authenticity, conditional on shade-related disclosures and verification procedures. For imagery to be defensible:

  • Photographs must be accurate, unretouched representations of typical results.
  • Disclosures should identify any stage-specific conditions (e.g., lighting, styling) that influence appearance.
  • If results vary by shade, the images should be labeled accordingly.

Influencer content and material connection disclosures Revlon committed to updating influencer content to include clear and conspicuous material connection disclosures. NAD treated this commitment as if it had been recommended, reinforcing that influencer transparency is a compliance priority. Buyers expect influencers to disclose sponsorships, and regulators increasingly enforce these norms.

Practical guidance: Shade disclosure, transparency, and context reduce the risk of misleading consumers. If a brand relies on a single-shade study, it should disclose that context conspicuously wherever the number appears.

Testing Methods: What the Studies Look Like and Why Protocols Matter

Understanding the kinds of tests at issue clarifies why NAD focuses on methodology. Common hair testing methods relevant to this case include:

  • Tensile strength testing: Hair samples are clamped and pulled until they break; the force at breakage and elongation metrics indicate hair strength and elasticity. Standardized equipment (e.g., universal testing machines) can produce reproducible data when protocols are consistent.
  • Combing force measurement: Instruments measure the force required to pass a comb through a hair tress under controlled conditions. Testing variables include comb type, combing speed, number of combing cycles, and hair hydration state (wet or dry).
  • Penetration studies: Techniques such as confocal microscopy, fluorescence tagging of ingredients, electron microscopy, or chemical extraction followed by chromatography can show whether specific molecules penetrate cuticle layers into the cortex.
  • Shine measurements: Instrumental gloss meters and image analysis quantify reflectance and gloss; lighting geometry and surface preparation heavily influence results.
  • Consumer-use or clinical trials: Panels of users apply products under normal-use conditions and report or are assessed on performance metrics like smoothness, shine, and breakage. These add ecological validity but require careful design to avoid bias.

Why precise protocols matter Small differences in set-up yield different outcomes. NAD’s acceptance of Revlon’s studies reflects their methodological soundness; NAD also noted that differences between Revlon’s and Henkel’s results could stem from legitimate, technical variations rather than fraud or incompetence.

Sponsors of testing should:

  • Use standardized, widely accepted protocols when available.
  • Document apparatus calibration, sample sourcing, preparation methods, and statistical analysis.
  • Where tests yield “up to” outcomes, provide context for what portion of test runs or hair types achieved that level of performance.

Testing transparency strengthens a brand’s position when claims are challenged.

Broader Industry Context: Why Self-Regulation and Evidence Standards Matter

Self-regulatory bodies such as NAD play a critical role in maintaining consumer trust and an even playing field. They evaluate claims based on evidence; their recommendations influence marketplace behavior and can deter regulatory escalation.

Several trends make this NAD decision instructive:

  • Consumers increasingly scrutinize beauty claims, searching for products that deliver real benefits. Brands respond with technical claims—“bond repair,” “internal reconstruction,” “bio-ceramides”—that require scientific backing.
  • Regulators and self-regulatory organizations are more attentive to implied claims conveyed through imagery and qualifiers.
  • Influencer marketing complicates the landscape. When sponsored content presents enhanced results without disclosure, it can mislead and attract enforcement.

For companies, a proactive approach to evidence and transparency reduces risk. Preparing a substantiation dossier that links each marketing claim to specific studies, with accessible summaries and caveats, can prevent disputes from escalating.

Legal and Commercial Consequences: What Compliance Looks Like

NAD’s recommendations are not legally binding but carry reputational and commercial consequences. Advertisers that ignore NAD findings risk:

  • Escalation to the National Advertising Review Board, which can issue stronger recommendations.
  • Complaints to federal agencies such as the Federal Trade Commission, particularly where deceptive advertising is alleged.
  • Consumer backlash on social media and erosion of trust.
  • Retailer pressure to withdraw non-compliant product claims from listings and packaging.

Revlon’s public statement that it “agrees to comply with NAD’s recommendations” reflects typical advertiser behavior. Compliance often means:

  • Revising packaging and digital copy to add qualifiers.
  • Adding shade-specific testing disclosures.
  • Correcting imagery and ensuring influencer disclosures.
  • Rerunning or supplementing studies if broader claims are desired.

Commercially, clear, defensible marketing reduces dispute-related costs and supports longer-term brand credibility.

Practical Rules for Brands: Drafting Claims That Withstand Scrutiny

The NAD decision suggests a practical checklist for brands developing performance claims for haircare and cosmetic products:

  1. Match claim scope to evidence scope.
    • If evidence is instrumentally measured on wet hair, specify that. If results pertain to a specific shade, disclose that.
  2. Avoid absolute repair language without robust, multi-method evidence.
    • “Repairs” or “restores” implies extensive structural change; “helps reduce breakage” or “contains a bond-repairing ingredient” is safer unless broad repair is demonstrably proven.
  3. Use “up to” carefully and responsibly.
    • Reserve “up to” for genuine maxima observed in testing and ensure consumer-facing materials clarify the conditions that produced that outcome.
  4. Ensure photography accurately represents typical outcomes.
    • Use unretouched images or disclose adjustments; label images with the shade, test conditions, and whether styling was used.
  5. Document testing protocols comprehensively.
    • Maintain chains of custody for hair samples, instrument calibration records, and clear statistical methods.
  6. Monitor influencer content proactively for disclosure compliance.
    • Provide influencers with required wording and confirm the inclusion of material connection disclosures before content goes live.
  7. Consider consumer-use studies for claims about everyday performance.
    • Lab tests provide precise measures, but consumer trials add relevance.

Following these steps aligns marketing with reasonable consumer expectations and builds a defensible position against challenges.

What Consumers Should Know When Evaluating Haircare Claims

Consumers can use a simple mental checklist when encountering claims like “bond repair,” “up to X%,” or dramatic before-and-after images:

  • Look for qualifiers: Does the packaging specify shade, hair type, or testing conditions?
  • Consider the context: Are images labeled and do they resemble typical user conditions?
  • Beware of absolutes: Claims that imply full structural repair are rare in cosmetic products; seek third-party reviews and user experiences.
  • Understand “up to”: This is a best-case figure, not necessarily typical performance.
  • Check for influencer disclosures: If an influencer promotes a product, look for #ad or explicit sponsorship language.

An informed consumer avoids unrealistic expectations and better matches product choice to personal needs.

The Path Forward: How Brands Can Strengthen Substantiation Strategies

Brands that want to make meaningful claims without risking regulatory or competitive challenges should invest in a layered evidence strategy:

  • Begin with mechanistic studies that show ingredient interaction with hair structures (penetration, binding).
  • Add functional laboratory assays (tensile strength, combing force, gloss measurements) with consistent, documented protocols.
  • Conduct consumer-use trials across representative hair types and shades to demonstrate typical performance.
  • Translate technical results into consumer-facing language that preserves accuracy without overstating effects.
  • Institutionalize substantiation review in product launch processes so marketing, R&D, and legal teams align on claim scope and presentation.

This multi-tier approach satisfies both scientific rigor and commercial needs. It ensures that marketing claims are not only technically supported but presented in a way that reflects realistic outcomes.

Market Impact: Why This Case Matters for Competing Brands and Retailers

The NAD decision communicates to competitors and retailers that challenges can yield targeted corrections rather than wholesale reversals. For rivals, it offers a roadmap for constructive challenges: focus on specific claims and present methodologically sound counter-evidence. For retailers, the ruling underlines the importance of accurate online product descriptions and imagery; sellers may be compelled to require manufacturers to provide substantiation or make packaging updates to remain listed.

Retail platforms that aggregate product claims have particular exposure. Consumers shop based on quick impression cues—headline claims and images—so platforms that host content must ensure accuracy or risk undermining trust. This decision may prompt tighter platform policies around claim substantiation and required disclosures for sponsored content.

Closing Observations on Industry Standards and Consumer Trust

The Revlon ColorSilk case illustrates a clear principle: the persuasive force of marketing must be matched by appropriately scoped evidence. Ingredient-focused descriptions, when supported by credible lab work, can stand. Claims that promise deep structural recovery require substantially more proof. Context and visuals matter; they shape reasonable consumer interpretation and can convert an otherwise accurate technical statement into a misleading impression.

Companies that align claims with robust, transparent evidence will maintain credibility and avoid regulatory entanglements. This alignment benefits consumers, who gain clearer expectations, and the industry, which preserves a level playing field for legitimate innovation.

FAQ

Q: Did NAD ban all of Revlon’s ColorSilk claims? A: No. NAD upheld several claims—such as the product being formulated “with a Bond Repair Complex,” and quantified anti-breakage and shine numbers—when Revlon produced reliable studies. NAD required discontinuation or modification of claims where the evidence did not support the consumer takeaway, most notably the “repairs hair from the inside out” claim and unqualified “smoother/silkier” claims measured only on wet hair.

Q: What specifically led NAD to reject the “repairs hair from the inside out” claim? A: NAD determined that the phrase implies substantial internal structural repair of the hair fiber. Revlon’s evidence showed ingredient penetration and some mechanical benefit, but not the breadth or depth of repair that consumers would reasonably infer. Because the data did not substantiate the strong restorative implication, NAD recommended discontinuation of that language.

Q: Can a brand use “up to” percentages safely? A: Yes, if the “up to” figure reflects actual testing maxima observed under clearly documented conditions. Brands should provide clear context—e.g., whether the test was performed on wet hair, a specific shade, or a particular hair type—and avoid suggesting that the “up to” result is typical for all users.

Q: What role did imagery and influencer content play in the decision? A: Imagery that suggests results inconsistent with the testing context can mislead. NAD evaluated before-and-after photographs and accepted Revlon’s assurances on authenticity conditional on added disclosures about shade variability. Revlon also committed to ensuring influencer posts include clear material connection disclosures; NAD treated that commitment as if recommended. Accurate images and transparent influencer labeling are essential.

Q: If my brand wants to claim “bond repair,” what evidence is needed? A: Use a layered approach: mechanistic studies showing ingredient penetration or bond interaction; functional tests (tensile strength, breakage reduction) demonstrating meaningful improvement; and consumer-use trials that show typical benefits. Describe testing conditions and limitations in marketing materials, and avoid language implying total restoration unless supported by comprehensive evidence.

Q: Will NAD’s recommendations stop at rewording, or can they lead to further actions? A: NAD’s recommendations are self-regulatory and focus on corrective measures. Most advertisers comply. If disagreements persist or the advertiser ignores recommendations, the matter can escalate to the National Advertising Review Board or attract regulatory attention from government agencies. Compliance reduces the risk of escalation.

Q: How should retailers handle claims like these on their e-commerce pages? A: Retailers should require manufacturers to provide substantiation for performance claims and ensure product pages display relevant qualifications (e.g., “wet-hair test,” shade tested). Retailers should also audit imagery and sponsored content for accurate disclosures and remove or flag claims that are ambiguous or unsupported.

Q: What does this decision mean for consumers choosing haircolor products? A: Consumers should read claims with an eye to qualifiers and context. Look for disclosures about the conditions under which claims were tested (wet vs dry hair, shade tested). Treat “up to” statements as best-case outcomes rather than guarantees. Consumer reviews and third-party testing can help bridge the gap between lab claims and real-world performance.

Q: How can companies avoid similar challenges in future advertising? A: Integrate substantiation into marketing development: align marketing language with precisely scoped studies; document test protocols; disclose testing conditions and shade variability; ensure influencer compliance; and use realistic imagery. Regularly review claims against current evidence and update materials when new data or broader testing become available.

Q: Are there broader regulatory trends affecting beauty and personal-care claims? A: Yes. Regulators and self-regulatory organizations are paying closer attention to implied claims, influencer disclosures, and the accuracy of comparative and superlative statements. Brands that prioritize transparency and robust substantiation will be better positioned to meet evolving scrutiny.
