Beauty, Cosmetics & Personal Care BS: Function of Beauty (functionofbeauty.com)
Function of Beauty provides significant technical substance regarding its production algorithm and founder credentials, elevating it above typical beauty fluff. The BS score is primarily driven by technical SEO failures (H1 tags) and a reliance on internal metrics rather than third-party lab transparency. It is a legitimate technology-led brand currently dressed in a somewhat generic, template-heavy web interface.
Immediately correct the H1 heading hierarchy so it reflects page content instead of the ‘Your cart’ technical error. Replace generic ‘Excellence’ headings with specific data points (e.g., ’15 Million Formulas’ instead of ‘Innovation Takes Shape’). Implement Person and Organization schema with sameAs links to the founders’ MIT credentials and LinkedIn profiles to close the authority gap. Link ‘scientifically proven’ claims directly to a PDF or page detailing the SOS system study methodology.
The site exhibits a healthy substance-to-fluff ratio, citing specific metrics such as 15 million unique products created and a proprietary algorithm that generates a formula every 13 seconds. However, information density is diluted by repetitive value propositions concerning ‘uniqueness’ and ‘individuality’ across all pages. High-density specifics like ‘2x stronger hair’ and ‘90% less breakage’ are anchored by footnotes, though the lack of a direct link to the study methodology keeps the score from being lower. The H1 tags are technically dysfunctional, showing ‘Your cart’ across multiple pages, which detracts from the professional density of the content.

There is minimal semantic drift between the homepage signal and the sub-page substance. The homepage H1 ‘Hair Care Customized by Hair Type’ is effectively supported by the About page’s technical explanation of the in-house chemist-led formulation and the proprietary production facility. The ‘Two Steps to Custom Haircare’ promise on the landing page is directly fulfilled by the Hair Quiz page, maintaining high messaging consistency despite the broken H1 technical implementation.

The site displays substantial review counts (averaging ~500 per page), but these appear to be internal measurements with only 2 proof_links_count detected per page, indicating a lack of third-party verification paths. Claims of being ‘Scientifically Proven’ and ‘Dermatologist Tested’ are prominent, yet the site fails to link to specific third-party lab certifications or peer-reviewed data. The inclusion of specific social handles like @kendall.toole and @marissa_lanae provides some social proof, though without direct FTC disclosure or linked case studies, they lean toward trust theatre.
The proof density is moderate; for every three vague assertions of ‘excellence,’ there is one hard piece of evidence (e.g., the specific names of founders or the mention of GirlStart partnership). The site provides specific filters and concerns in the JSON data for its ‘Shop All’ page, proving that the customization isn’t just a front-end marketing layer but a deeply integrated product architecture. However, the ratio of verifiable third-party links to internal marketing claims remains low.

The brand leans heavily on industry-standard ‘clean beauty’ clichés, including the high-frequency use of ‘cruelty-free’, ‘vegan’, and ‘sulfate-free’ which are found in almost all modern competitors. The ‘The Function Standard’ section is a template-style block that uses generic positioning (‘no compromises’, ‘powerful science’). However, the specific MIT-founder background and the ’13-second formulation’ claim provide a unique fingerprint that prevents the site from feeling like a pure commodity clone.
Authority is established through the naming of specific founders (Zahir Dossa, Hien Nguyen Kaplan, Josh Maciejewski) and their credentials (MIT engineers, seasoned chemists). The primary authority gap is technical: the schema_json is null across the crawl, and the H1 hierarchy is broken, which contradicts the brand’s positioning as a high-tech, data-driven engineering marvel. This technical implementation failure suggests a ‘template-skin’ reality that doesn’t quite match the ‘advanced production facility’ narrative.
The site makes bold performance claims such as ‘2x stronger hair’ and ‘90% less breakage’ which are technically substantiated by a footnote mentioning an ‘SOS system vs untreated hair.’ While not a complete disconnect, the lack of a visible, accessible lab report or clinical summary for these ‘scientifically proven’ results creates a gap between marketing tone and forensic proof. The before-and-after testimonials are descriptive but lack disclosure of the methodology or timeframes for the visual results.
Beauty, Cosmetics & Personal Care BS: Function of Beauty (functionofbeauty.com)
The content perfectly aligns with the Beauty, Cosmetics & Personal Care industry, focusing on customized hair and body care formulations. The use of industry-specific jargon like sulfate-free, paraben-free, and dermatologist-tested confirms its placement in the custom cosmeceutical niche.

“The score of 32 reflects a site with high substance (specific founders, clear business model, unique tech) but poor technical and trust execution. The Information Density (11) and Commodity Fingerprint (7) pillars were the primary drivers due to repetitive 'clean beauty' jargon and broken H1 tags. The Identity and Authority score (6) was penalized for the missing schema despite the high-quality founder background.”
