Annurca apple supplement safely increases hair growth and keratin in humans.
research Demethylation of methionine and keratin damage in human hair
Copper and iron cause keratin damage in hair by converting methionine to homocysteine.
research The Keratins of the Human Beard Hair Medulla: The Riddle in the Middle
Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.
research Keratin‐based particles for protection and restoration of hair properties
Keratin-based particles safely improve hair strength, smoothness, and heat protection.
research Induction of Hair Keratins Expression by an Annurca Apple-Based Nutraceutical Formulation in Human Follicular Cells
