D-Lab — Keratin Absolute

Keratin makes up approximately 90% of hair structure, but its oral bioavailability directly depends on the extraction process. Standard keratins derived from chemical processes are often denatured and poorly assimilated. D-Lab keratin is obtained through a patented process that preserves the native structure of amino acids and reduces molecular weight to optimize intestinal absorption — this parameter justifies the selection of this reference. The clinical study on 48 women over 90 days shows results consistent with the claimed mechanism. A nuance to add: 48 women is an acceptable but limited sample size; the results are encouraging and consistent with the literature on hydrolyzed keratin, without constituting level 1 evidence. Clinical vigilance point: traces of sulfites, a formal contraindication for patients allergic to sulfites. Animal origin (sheep's wool) to be noted for vegetarian and vegan profiles. No known drug interactions. This supplement is part of the REPAIR pack, providing oral support for the topical repair products in this routine.
