    TLDR Minoxidil reduces lysine hydroxylase in skin cells.
    Minoxidil, a drug used to treat hair loss, was found to specifically decrease the amount of lysine hydroxylase protein in cultured human skin fibroblasts. This decrease is due to a decrease in its synthesis at a pretranslational level, as minoxidil markedly decreases the amount of lysine hydroxylase mRNA. The decrease in the lysine hydroxylase mRNA appeared to be highly specific, as no changes were seen in the amounts of mRNAs for the a- or B-subunits of proline 4-hydroxylase or for y-actin.

      Regrowing hairline without the use of Minoxidil or Finasteride, and instead using mechanical stimulation such as Derma Roller, Nizoral, Zinc Pyrithione, Scalp Massage, Scalp Exercise, Fish Oil and other topical solutions. It is cautioned that there are risks associated with not using medically-prescribed treatments, but it is suggested to consider mechanical stimulation in addition to those prescribed treatments.

      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.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.
