      community Does melatonin dissolve in isopropyl alcohol

      in Technology  6 upvotes 3 years ago
      The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hair growth by affecting certain cellular signaling pathways and has anti-androgenic effects.

      in Treatment  58 upvotes 4 years ago
      A user found out they are vitamin D deficient and was prescribed high-dose vitamin D supplements, asking if others had similar experiences and if it improved their hair. Some shared improved mood and testosterone levels after treatment, while another combined vitamin D supplements with finasteride due to family history of baldness.

      community How Does Exosome Therapy Work for Hair Loss?

      in Research/Science  5 upvotes 2 years ago
      Exosome hair therapy involves injecting stem cell-derived exosomes into the scalp to boost hair follicle regeneration and repair. Exosomes, which are not stem cells but products of them, contain bioactive chemicals and specific growth factors that promote new blood vessel formation, increase cell proliferation, reduce inflammation, and improve tissue repair, all crucial for hair health.

      community Polydopamine Synergizes with Quercetin Nanosystem to Reshape the Perifollicular Microenvironment for Accelerating Hair Regrowth in Androgenetic Alopecia.

      in Research/Science  12 upvotes 1 year ago
      A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
