Three-Dimensional Printing in Trichology: A Narrative Mini-Review – Where Are We Now?

This review discusses the potential of 3D bioprinting in trichology, particularly for treating alopecia by creating hair follicles from synthetic and natural polymers. The process involves layering cell populations to form skin structures, with applications in androgenetic alopecia, wound healing, surgical templates, and alternatives to animal testing. Despite its promise, challenges such as high maintenance costs, balancing viability and printability, and current limitations in human application remain. While 3D bioprinting shows promise in preclinical settings, further optimization and cost reduction are needed for clinical use.
