A Randomized Pilot Study to Compare Hair Follicle Cell Suspensions Prepared Using Trypsin Alone Versus Trypsin in Combination with Collagenase Type I for Transplantation in Vitiligo

This study found that hair growth was maintained in alopecic sites using scalp autografts with triamcinolone acetonide, but homografts were typically rejected.

In this study, different donor and recipient site preparation techniques for melanocyte-keratinocyte suspension were associated with similar repigmentation outcomes in stable vitiligo, but efficacy varied by body site.

The abstract reports that non-cultured cellular grafting has become a prevalent and cost-effective method for treating stable vitiligo, with safety and effectiveness confirmed by two decades of studies. It critiques strict legislative oversight, suggesting it might unnecessarily increase costs and limit patient access.

This review discusses advancements in regenerative medicine for hair loss treatments, highlighting stem cell techniques for rejuvenating or creating hair follicles, but provides no new clinical results.

This study found that a topical herbal solution significantly increased hair diameter and density in men with androgenetic alopecia compared to minoxidil after 36 weeks of treatment.
