A Genetic Electrophoretic Variant of High-Sulfur Hair Proteins for Forensic Hair Comparisons: Characterization of Variant High-Sulfur Proteins of Human Hair

    February 1989 in “ PubMed ”
    B Miyake
    TLDR A genetic hair protein variant is more common in Japanese people and is inherited.
    In 1989, a study investigated genetic electrophoretic variants in high-sulfur proteins of human hair for forensic purposes. The research analyzed 150 Japanese and 21 Caucasian hair samples, finding that 43 Japanese samples and 1 Caucasian sample exhibited an additional high-sulfur protein band, indicating a variant. This variant protein had an apparent molecular weight of 30 kDa and isoelectric points between 3.3-3.4. Family studies involving 21 matings and 49 children suggested that the variant was inherited in an autosomal manner.

      community Does onion juice actually stop hair fall, or is it just hype?

      in Treatment 3 months ago
      Onion juice may temporarily improve hair health by boosting blood circulation and providing antibacterial benefits, but it is ineffective against genetic or hormonal hair loss. Proven treatments like minoxidil and finasteride are recommended for more reliable results.
