OGX Bond Protein Repair Heat Protect Spray
OGX is one of the brands that actually outlined two different third-party lab methods: flat ironing at 450°F with DSC to assess keratin denaturation, and automated repeated grooming to quantify breakage reduction. I liked that they acknowledged the difference: DSC is super sensitive (more pass/fail), while breakage testing is more obviously tied to what consumers notice.
