These unique collagens are responsible for skin strength, elasticity, and strong anchoring of hair in the hair follicle. While keratin from animal sources is insoluble and digestible, our unique keratin formulation sets us apart, as it is digestible.Studies with keraGEN-IV\u00ae in human keratinocytes have shown that increased collagen IV expression is induced by the protein.\u00b3 Further preclinical work demonstrated that collagen IV expression is induced around the hair follicle.\u2074 In a placebo-controlled human clinical study\u2075, the use of keraGEN-IV\u00ae improved skin elasticity, hair pull scores and nail quality after 60 days.<\/p>\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\t<\/div>\n\n\t            \n\t\t\t<\/div>\n\n            \n\t\t\t\t\t<\/div>\n\t<\/div>\n\n\t<div class=\"c-block__col c-block__media\">\n\t\t\t<div class=\"c-image front-h-left front-v-center main-h-full main-v-center r-1x1 is-image\">\n\n\t\t\t\t\t<div class=\"c-image__media c-image__primary\">\n\t\t\t\t<img decoding=\"async\" class=\"c-image__src lazy\" loading=\"lazy\" src=\"https:\/\/www.iff.com\/wp-content\/uploads\/2024\/12\/Enhancing-the-Hair-Journey_shutterstock_2308188405-897x1024.png\"  alt=\"Enhancing the Hair Journey_shutterstock_2308188405\" width=\"897\" height=\"1024\"\/>\t\t\t<\/div>\n\t\t\n\t\t\n\t<\/div>\n\t\n\t\t\t<\/div>\n<\/div>\n\n\t\t<\/div>\n\n\t<\/div>\n\n\t\n<\/div>\n\n\n<div class=\"m-block  gt gb l-content-simple-1\"  >\n\n\t\n\t\n\t<div class=\"m-block__container container\" style=\"\">\n\n\t\t<div class=\"l-heading text-left l-heading-v1\">\n\n\t\t\t<div class=\"l-heading__content\">\n\t\t\t\t\t<div class=\"c-heading__description is-wysiwyg\">\n\t\t\t\t\t<p><\/small><strong>References: 1. <\/strong>Beer et al., International Journal of Cosmetic Science, 2013;
