Hair Follicle Group And Skin Follicle Population Of Australian Merino Sheep

    HB Carter, WH Clarke
    TLDR Certain hair follicle traits in Merino sheep may be inherited.
    The study examined skin specimens from 495 Australian Merino ewes across 22 flocks, representing four important strains. Using a standard biopsy method, the researchers analyzed histological sections to estimate various follicle population densities and fibre diameters. The data, including mean and standard error for each flock, serve as a foundation for future genetic studies on fleece structure. The study highlights the potential hereditary origin of certain extreme variants in hair follicle groups.

      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.

      In this conversation, 4990 discussed various treatments for hair loss, including oral minoxidil, PRP, transplan, Jak inhibitors, Dutasteride, Finasteride, Olumiant, Ketoconazole, RU58841, microneedling, baricitinib, and CCCA. They recommended scalp biopsies in unclear cases of DUPA, twice weekly to twice daily shampooing for topical minoxidil users, and two sessions spaced one month apart with follow up at month three to determine the effectiveness of PRP treatment.
