    TLDR High glycine–tyrosine keratin-associated proteins help make hair strong and maintain its shape.
    The study hypothesized that high glycine-tyrosine keratin-associated proteins (HGT KAPs) contributed to hair's mechanical strength and shape by bridging the head domains of intermediate filaments (IFs) and binding to both IFs and the C-terminus of desmoplakin (DPCT). This was supported by protein interaction analyses, including Western blot, isothermal titration calorimetry (ITC), and circular dichroism (CD), which showed strong binding interactions between HGT KAPs and the head domain of K85, a trichocyte IF protein.

      A 30-year-old man with diffuse hair thinning shared his hair regrowth regimen, which includes increasing Vitamin D intake, taking oral castor oil, using a dermapen, and various supplements like Glycine, K2, Vitamin E, Vitamin C, Aspirin, Sodium Bicarbonate, and a multivitamin. He also mentioned inconsistent use of Minoxidil, Peppermint Oil, Zix, and topical Castor Oil, and negative side effects from Finasteride, RU58841, and Nizoral.

      A topical solution called "Multi-Peptide Serum for Hair Density" by The Ordinary Company, which contains several ingredients that are used in alternatives to Minoxidil and was found to have better results than 5% Minoxidil in a study. People who have tried it shared their experiences with the serum as well.

      community Vitamin Deficiency: “Severely” Low on Vitamin D

      in Update  15 upvotes 1 year ago
      A user experiencing significant hair loss found they had a severe vitamin D deficiency and was prescribed 50,000IU vitamin D pills, likely to be taken weekly. They are questioning if the deficiency could be the cause of their hair loss and if correcting it could stop the shedding and improve hair recovery.
