    GlossaryProliferating Cell Nuclear Antigen

    protein marker for cell division and DNA repair

    Proliferating Cell Nuclear Antigen (PCNA) is a protein that acts as a marker for cell proliferation, meaning it helps identify cells that are actively dividing. It plays a crucial role in DNA replication and repair, making it important for both normal cell growth and the response to DNA damage.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 4 months ago
      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community PP405 - hair stem cell stimulation

      in Research/Science  51 upvotes 9 months ago
      PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.

      community Novel effect of sildenafil (cialis) on hair growth

      in Research/Science  21 upvotes 2 years ago
      Sildenafil (Viagra) shows potential for hair growth by enhancing dermal papilla cell proliferation and stimulating perifollicular vessel formation. Users discuss the possibility of using Cialis (tadalafil) similarly, noting its benefits and side effects.

      community How Does Exosome Therapy Work for Hair Loss?

      in Research/Science  5 upvotes 1 year 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  13 upvotes 6 months 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.

      community abusing caffeine boosts DHT levels!

      in Research/Science  1 upvotes 2 months ago
      Caffeine intake may increase DHT levels, but its impact on hair loss is minimal compared to genetic factors. Excessive caffeine can cause health issues, and its effects on hair loss are not directly applicable to humans based on rat studies.

      community Hair theory Scar tissue and Verteporfin

      in Chat  26 upvotes 6 months ago
      A user suggests that deeper microneedling with Verteporfin injections might help regrow hair in areas with scar tissue, alongside a DHT blocker. Another user explains that hair loss might be due to reduced Wnt/β-Catenin signaling and suggests that treatments like Minoxidil, Finasteride, and microneedling could potentially reverse it.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  143 upvotes 10 months ago
      The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.

      community Verteporfin and Microneedling

      in Treatments 6 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
