    GlossaryDermis (dermal layer)

    thick skin layer beneath epidermis with connective tissue and glands

    The dermis is the thick layer of skin beneath the outer epidermis. It contains connective tissue, blood vessels, hair follicles, and glands, playing a crucial role in skin's structural integrity and elasticity. This layer is essential for thermoregulation and sensation, as it houses nerve endings that respond to touch, pain, and temperature.

      community Testosterone in Reference Range Doesn't Cause Hair Loss

      in Research/Science  51 upvotes 9 months ago
      Testosterone within the normal range does not significantly contribute to male pattern baldness (MPB); DHT is the main factor that can be controlled. Genetics play a crucial role in hair loss, and treatments like finasteride and dutasteride, which block DHT, can help despite potentially raising testosterone levels.

      community Verteporfin and Microneedling

      in Treatments 5 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.
