    TLDR Using tissue expanders and hyaluronidase in scalp reduction surgery allows for more scalp removal and easier surgery.
    In the 1991 study, scalp reduction surgery was enhanced by using intraoperative tissue expanders and the addition of hyaluronidase to the local anesthetic. The study involved 20 patients and demonstrated that intraoperative tissue expansion increased the amount of excised scalp by 20-30% over standard reduction techniques. The use of hyaluronidase facilitated the diffusion of the anesthetic, improving anesthesia and making dissection easier. These two adjuncts to scalp reduction surgery were found to be beneficial, with intraoperative tissue expansion also reducing the number of required surgeries for crown alopecia by allowing more bald scalp to be resected in a single procedure.

      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.
