<h1>Consumer haircare relaunch raises FTC Section 5, cosmetic substantiation, influencer disclosure, IP and data privacy risks</h1> A consumer-products company relaunched a legacy haircare line as a multi-product Ayurvedic/science hybrid, touting clinical results, sustainability certification, and a celebrity endorsement. Legal issues include regulatory compliance for cosmetics claims and clinical substantiation, truth-in-advertising risks from efficacy statistics and medical-sounding language, disclosure requirements for paid endorsements, intellectual property and trademark considerations around the reformulation and new name, data-privacy and consent obligations for in-store scalp microcamera diagnostics, and potential greenwashing scrutiny tied to sustainability claims. Vendors, marketing materials, and clinical study documentation should be reviewed to mitigate regulatory, consumer-protection, and advertising-liability exposure.
