In National Advertising Division Challenge, SharkNinja Voluntarily Modifies “Fastest Blowout” Claims for Glossi 2-in-1 Hot Tool and Air Glosser

Following a BBB National Programs’ National Advertising Division Fast-Track SWIFT challenge brought by Dyson, Inc., SharkNinja Operating, LLC voluntarily modified “fastest…blowout” performance claims made for its Shark Glossi 2-in-1 Hot Tool and Air Glosser.

New York, NY, May 27, 2026 (GLOBE NEWSWIRE) -- Following a BBB National Programs’ National Advertising Division Fast-Track SWIFT challenge brought by Dyson, Inc., SharkNinja Operating, LLC voluntarily modified “fastest…blowout” performance claims made for its Shark Glossi 2-in-1 Hot Tool and Air Glosser.

Fast-Track SWIFT is an expedited process for single-issue advertising cases reviewed by the National Advertising Division (NAD).

Dyson and Shark make competing hair dryers and stylers. At issue before NAD were Shark’s “fastest blowout” claims on product packaging, its website, and social media, including “The FASTEST, BOUNCY, BLOWOUT WITHOUT THE FRIZZ that lasts all day” and “unlock the fastest, glossiest bouncy blowout ever.” The challenge solely focused on whether comparing average air velocity alone is a good fit for the challenged superlative performance claim.

During the course of the challenge, Shark informed NAD that it had permanently modified its advertising to make clear that the “fastest blowout” claim is based on comparative dry-time testing that it had conducted, rather than air velocity alone. Based on this modification, NAD did not address the substance of the challenge. This voluntarily modified version of the claim will be treated, for compliance purposes, as though NAD recommended they be modified.
