    TLDR A new type of amniotic tissue graft improves wound healing better than other grafts.
    In 2017, a study was conducted to compare the effectiveness of different types of amniotic-derived tissue grafts in wound healing. The study used a full-thickness rat wound model and treated the wounds with either dehydrated amnion/chorion (dHACM) grafts, dHACM meshed grafts, hypothermically stored amniotic membrane (HSAM) grafts, or left the wound ungrafted. The results showed that all amniotic-derived tissue grafts improved healing over ungrafted wounds, with more normal-appearing dermal matrix architecture, epidermal structure, and maturity. However, the HSAM grafts promoted greater tissue regeneration than the dHACM meshed grafts, as measured by the presence of basket-weave collagen matrix and formation of follicles and glands. The study concluded that the processing of amniotic tissues significantly affects the quality of wound healing.

      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.

      A potential treatment for hair loss that involves injecting fat into the scalp; the role of testosterone and estrogen in thinning fat tissue under the skin; research on using lard to treat androgenic alopecia, as well as PRP + ACELL/amniotic stem cell treatments; and ongoing clinical trials by doctors involved in the study.
