    TLDR Keratin proteins are consistent across different hair types from the same person.
    The study compared the electrophoretic patterns of proteins extracted from various types of human hair (head, pubic, breast, beard, arm, leg, axillary, and eyebrow) using sodium dodecyl sulfate-polyacrylamide gel electrophoresis. It found that the keratin phenotypes were consistent across different hair types from the same individual. Additionally, keratin typing could be successfully performed after determining the ABH blood group using mixed cell agglutination with the same hair samples.

      community Keratin microspheres - breakthrough

      in Research/Science  13 upvotes 9 months 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.
