{"title":"Resorcinol Free Hair Dye: Why This One Ingredient Change Matters More Than You Think","description":"\u003cp dir=\"ltr\"\u003e\u003cspan\u003eWhen people evaluate hair dye safety, they typically focus on PPD. Para-phenylenediamine is the most discussed allergen in the hair dye category, and avoiding it is the first concern for people with reactive scalps.
