    TLDR Human hair color is influenced by complex biochemical processes involving enzymes and reactive oxygen species.
    The document discussed the complex biochemistry of human hair pigmentation, focusing on the role of the hair follicle melanocyte and the enzyme tyrosinase in melanin formation. It highlighted the importance of understanding various factors such as enzyme kinetics, substrate supply, pH levels, and cAMP signaling in the pigmentation process. The study also emphasized the impact of reactive oxygen species on enzyme regulation and the significance of methionine sulfoxide repair via methionine sulfoxide reductases A and B (MSRA and B). The research primarily relied on data from the C57BL/6 mouse model, and it remained uncertain whether these findings could be directly applied to humans.

      community New Hair Loss Treatment: Adipose Derived Secretomes

      in Research/Science  17 upvotes 3 months ago
      Adipose-derived stem cell secretome showed significant improvement in hair density and growth, especially when combined with minoxidil, suggesting a synergistic effect. The study had limitations, including a small sample size and potential bias.

      community Great news recently for people with hairloss!

      in Research/Science  113 upvotes 4 months ago
      A potential treatment for alopecia involving a protein that calms hair follicles has shown promise in rats, but skepticism remains about its applicability to humans. Many users express doubt about the timeline for effective hair loss treatments, comparing it to past unfulfilled promises.

      community Is there any new drug that looks promising ?

      in Research/Science  25 upvotes 1 year ago
      The conversation discusses GT20029, a drug in Phase II trials that targets androgen receptors with minimal systemic effects, and TDM-105795, a growth stimulant with a different mechanism than minoxidil that may revive papilla stem cells. Both are potential new treatments for hair loss.

      community Forgotten Hair Loss Peptide by L'Oreal: KPV

      in Research/Science  5 upvotes 1 year ago
      KPV, a peptide patented by L'Oreal, may promote hair growth and reduce hair loss by extending the anagen phase and has anti-inflammatory properties. It could be combined with treatments like minoxidil for enhanced effects.
