In this video I’m answering the question I keep seeing in my comments: are heat protectants basically a scam, and are brands lying about the temperatures they claim on the label? To get a real answer, I reached out to an attorney to understand what the actual regulations are. And the key takeaway is this: brands can sell heat protectants without prior government review, but they’re still required to comply with the law from day one. According to the attorney, brands need scientific evidence to support heat protection claims, the testing has to show protection at the temperature they’re claiming, and they have to keep test reports on file in case regulators challenge them. I also share the most common validation methods I found in my own research—especially DSC (a clear pass/fail thermal analysis at a specific temperature) and repeated grooming (brushing hair tresses to collect and measure breakage). Because regulations don’t guarantee every brand is honest, I emailed the brands I recommend in the Abbey Yung method to ask what testing they use. Several confirmed methods like DSC, repeated grooming, thermal imaging, and damage evaluation at 450°F. So no, the “all heat protectants are a total scam” rumor doesn’t hold up—at least not for the brands that were willing to disclose their testing approaches.
