Immunochemical Studies on Blood Group A Substance from Human Hair

November 1977 in “ International Journal of Legal Medicine ”

Koichiro Kishi, Shoei ISEKI

blood group A blood group H glycolipid N-acetylgalactosamine

TLDR Human hair contains a substance that shows blood group A activity.

The study extracted blood group A-active substances from human hair using methanol-ethyl ether or chloroform-methanol. The serological activity of these substances was destroyed by an A-decomposing enzyme from Clostridium tertium, which led to the development of blood group H activity. This indicated that the hair extract contained a blood group A-active glycolipid with N-acetylgalactosamine as the non-reducing sugar.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

community How far are we from a treatment better than finasteride?

Dutasteride is more effective than finasteride for hair loss as it blocks more of the enzyme causing hair loss. New treatments like stem cell therapies and alternatives to minoxidil are being explored, but major advancements are still years away.
