    TLDR Protein composition greatly affects the function of keratin biomaterials.
    The study explored the development of keratin-based biomaterials derived from human hair, focusing on the extraction and purification of keratins to improve their mechanical properties for biomedical applications. By using reductive chemistry, the researchers extracted keratins and separated them into α- and γ-fractions, which were then recombined to create "meta-kerateines" with varied properties. The findings indicated that purified keratin extracts could form more robust and stable biomaterials compared to crude extracts, highlighting the potential for designing materials with specific physical, chemical, and biological characteristics for tissue engineering.

      community Keratin microspheres - breakthrough

      in Research/Science  14 upvotes 2 years ago
      A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

      A user shared their daily hair loss treatment routine, which includes 1mg of oral finasteride, 1mg of oral minoxidil, 1ml of castor oil, biotin, collagen, multivitamins, zinc, magnesium, liver supplements, RU58841 every night, and ketoconazole shampoo twice a week. They also mentioned a healthy lifestyle and a past unsuccessful hair transplant, but have experienced hair regrowth and thickening since starting their current regimen.
