    GlossaryHair Growth (hair formation)

    process where hair strands develop from follicles in the skin

    Hair growth refers to the process by which hair strands develop from hair follicles located in the skin. This process involves three main phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). During the anagen phase, cells in the hair bulb divide rapidly, adding to the hair shaft and causing it to lengthen. Factors such as genetics, hormones, and overall health can influence the rate and quality of hair growth.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 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.

      HairClone aims to rejuvenate miniaturizing hair follicles through follicle banking and cell expansion, with treatments potentially available in the UK by 2022. The process involves extracting, storing, and cloning hair follicles, but full regenerative treatments will take many years to develop.

      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.
