Dermal-Epidermal Interactions in Hair Follicle Development and Cycling

    October 1988 in “ Clinics in dermatology ”

    TLDR The dermal papilla interacts with the epidermis to control hair growth and development.
    The document discussed the role of dermal-epidermal interactions in hair follicle development and cycling, emphasizing the importance of the dermal papilla. The dermal papilla, a stable population of specialized fibroblasts, interacted with the epidermis to ensure follicle development and continued to influence the follicular epidermis throughout the hair cycle. The study suggested that the papilla provided factors that stimulated epidermal proliferation, initiating and sustaining anagen and follicle morphogenesis. Additionally, the dermal component of the follicle mediated the influence of systemic factors, such as androgens, on hair growth. The findings indicated that understanding these interactions could reveal intrinsic control mechanisms regulating hair development and growth in both normal and disease states.

      The conversation is about using vitamin C and Magnesium L-Threonate for hair growth by reducing DHT binding to dermal papilla cells. The original post about vitamin C's pH levels and sebum control was possibly removed by a moderator.

      A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

      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.
