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

In this review, researchers explore various treatment options for alopecia, focusing on nano-drug delivery systems using plant-based substances, which are potentially effective and less harmful than current treatments, while also highlighting emerging trends such as 3D bioprinting and plant extracts for future therapies.

This study reviews 3D printing's role in neurology, highlighting its potential to enhance hair restoration and scalp therapy through personalized solutions, while acknowledging the challenges of regulatory issues and the need for further research on long-term effects.

This study reviews advancements in hair follicle regeneration, discussing the benefits and limitations of methods such as organ germ assembling, stem cell induction, and bioprinting, while highlighting the challenges of replicating embryonic signals and finding suitable cell sources for clinical applications.

In this study, researchers used 3D bioprinting with skin stem cells and specific hydrogels to create artificial skin that successfully promoted complete wound healing and the regeneration of skin structures, including hair follicles and blood vessels, in mice.

In this study, researchers used 3D bioprinting to successfully create engineered skin tissues with hair follicle-like structures, potentially enhancing skin grafts and safety testing for chemical compounds by more closely mimicking natural skin complexity.

This review discusses various tissue engineering approaches for hair follicle regeneration and biomaterials used, emphasizing its potential despite current clinical challenges.

This review discusses treatment options for androgenetic alopecia, highlighting the need for personalized, evidence-based approaches but reports no new clinical results.

This study found that both PHDPE and ePTFE hair-bearing scaffolds were well tolerated in a rat model, with minimal infection or extrusion, though artificial hair showed progressive loss over time.

This study suggests that stress negatively affects hair growth by inducing inflammation and early hair cycle transitions in mice, which might inform strategies for managing stress-related hair loss in humans.
