Oz","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eEvery conventional heat protectant does the same thing: lays a coating over the outside of the hair. The problem is that a 450°F flat iron doesn't stay on the outside. Heat travels into the cortex, where it destabilizes the proteins that hold hair together — and that's where the dryness, dullness, color fade and breakage actually begin.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eHeatBounce is built around \u003cstrong\u003eresilicore™\u003c\/strong\u003e, a heat-shielding technology inspired by resilin, a protein found in nature that withstands extreme temperatures.
