1. DEFINING CRUELTY-FREE IN HAIRCARE
What “Cruelty-Free” Means to Overtone
-
No Animal Testing: No raw materials, intermediates, or finished products are ever tested on animals at any point in development.
-
No Animal-Derived By-Products: We exclude lanolin, keratin from hooves, and any ingredient sourced from animal slaughter.
-
Ethical Supplier Practices: All our suppliers must share our commitment to animal welfare and confirm no animal testing throughout their supply chain.
Why It Matters
-
Ethical Responsibility: Millions of animals worldwide suffer in the name of cosmetic testing—Overtone chooses compassion without sacrificing product performance.
-
Consumer Demand: According to recent surveys, 72% of beauty buyers seek cruelty-free certification before purchasing hair color and care products.
-
Regulatory Alignment: We exceed legal standards in regions where animal testing is still permitted, rather than simply comply with minimum requirements.
2. INGREDIENT SOURCING & SUPPLIER AUDITS
Rigorous Supplier Vetting
-
Documentation Review
-
We require detailed documentation from each supplier—certificates of analysis, origin tracing, and no-animal-testing declarations.
-
-
On-Site Audits
-
Third-party auditors visit our key suppliers annually to verify that no animal tests occur at any production stage.
-
-
Raw Material Substitution
-
If a supplier cannot guarantee cruelty-free status, we source alternative, ethically equivalent ingredients or develop in-house botanical alternatives.
-
Transparency & Traceability
-
Batch-Level Tracking: Every ingredient batch is assigned a unique code in our ERP system—this ensures any material can be traced back to its harvest or manufacturing origin.
-
Public Disclosure: Our Committed to Cruelty-Free page lists every raw material, supplier, and certification we hold, updated quarterly.
By rejecting these ingredients outright, we ensure every Overtone product is safe, effective, and aligned with modern clean beauty standards.
3. IN-HOUSE SAFETY & EFFICACY TESTING
Cell-Based & In Silico Methods
-
Reconstructed Human Epidermis (RHE): We test for irritation potential using lab-grown skin models, which mimic human scalp response.
-
3D Hair Follicle Cultures: Our in vitro follicle assays evaluate pigment adhesion, color longevity, and cytotoxicity without animal involvement.
-
Computer Modeling (In Silico): Advanced algorithms predict allergenicity and phototoxicity, reducing the need for even in vitro tests.
Performance Validation
-
Colorfastness Trials: Panels of trained technicians apply semi-permanent ColorConditioner across multiple hair types, simulating up to 15 wash cycles to measure fade resistance.
-
Moisture & Strength Testing: We use standardized tensile-strength meters to assess breakage before and after repeated applications, ensuring our Conditioning Masks and shampoos improve hair integrity.
-
Consumer Use Studies: Volunteer participants (under IRB-approved protocols) track real-world performance—shine, slip, and scalp comfort—over a 6-week period.
Pro Tip: All in-house tests follow OECD guidelines for reliability and reproducibility, ensuring data integrity and regulatory readiness.
4. THIRD-PARTY CERTIFICATION & COMPLIANCE
-
Recognized Cruelty-Free Seals
-
Leaping Bunny Approved: Overtone is certified by the Coalition for Consumer Information on Cosmetics, granting the Leaping Bunny logo to our entire haircare line.
-
PETA Beauty Without Bunnies: Additional endorsement from PETA’s global cruelty-free program.

-
Global Regulatory Alignment
-
EU Cosmetics Regulation (EC) No 1223/2009: Prohibits animal testing for cosmetics ingredients—Overtone has adhered since inception.
-

-
ISO 10993-5 & 10993-10: We follow these international standards for in vitro cytotoxicity and irritation testing, reinforcing our commitment to safety without animals.
-
5. CONTINUOUS IMPROVEMENT & TRANSPARENCY
Iterative Formula Enhancement
-
Green Chemistry Goals: We invest in R&D to replace any potentially harmful synthetic ingredients with plant-based or biodegradable alternatives.
-
Ingredient Review Board: An internal cross-functional team (R&D, Regulatory, Marketing) meets quarterly to review emerging safety data and update formulations proactively.
Customer-Facing Transparency

Full Ingredient Disclosure: Every product page lists 100% of raw materials by INCI name—no “proprietary blends” or hidden fragrance panels.
