    TLDR Current hair regeneration methods show promise but face challenges in maintaining cell effectiveness and creating the right environment for hair growth.
    The article reviews current methods and challenges in hair regeneration using cells derived from human hair follicles, focusing on the complex interaction between mesenchymal and epithelial cells. It highlights the potential of dermal papilla (DP) and epithelial stem cells (Epi-SCs) in generating new hair follicles but notes difficulties due to gene loss during cell culture and insufficient cell numbers. Techniques such as 3D cultures, signaling pathway activation, and the use of small molecules or exosomes are explored to restore the hair-inducing ability of DP cells. Despite advancements, challenges remain in maintaining cell inductivity and creating a conducive microenvironment for hair growth, emphasizing the need for improved methods to achieve functional and cycling hair follicles using only human cells.

      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.

      Microneedling for hair restoration involves daily use of a 0.3 mm device and weekly use of a 0.5 mm device. Combining microneedling with Minoxidil can enhance hair growth.

      community HairClone: Good info from their site

      in Technology  10 upvotes 2 years ago
      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.
