Advances in Stem Cell-Based Therapy for Hair Loss

This review discusses the potential of stem cell-based therapies, particularly involving stem cell-derived conditioned medium and exosomes, for hair regeneration in nonscarring alopecia, but it reports no new clinical outcomes.

This study found that injecting autologous dermal sheath cup cells significantly increased hair density and diameter in male and female pattern hair loss compared to a placebo for up to 9 months.

This study found that intradermal administration of adipose-derived stem cell–conditioned medium significantly increased hair density and dermal thickness, suggesting potential regenerative effects on both hair follicles and the interfollicular scalp in patients with alopecia.

This review discusses current uses and advancements in mesenchymal stem cell-derived conditioned media as a potential regenerative therapy but does not present new clinical findings.

This article reviews the potential of adipose-derived and Wharton’s jelly stem cells in alopecia treatment but presents no new clinical findings, highlighting their potential benefits and limitations in regenerative medicine.

In this study, patients receiving adipose-derived stromal vascular cell transplantation for alopecia areata experienced significant hair regeneration, increased growth, and improved hair quality after 3 and 6 months, indicating potential efficacy of this stem cell-based therapy for hair loss.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

This article reviews the potential advantages of secretome derivatives from human uterine cervical stem cells in MSC therapy and notes the need for regulatory standards to ensure safety and efficacy.

This study found that scalp injection of fat enriched with stem cells may offer a promising alternative for treating early genetic alopecia in both men and women.

This study reported that using human follicle stem cells isolated from hair bulge areas increased hair density by about 29% over baseline in patients with androgenetic alopecia, with significant improvements observed 23 weeks after the last treatment.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This study observed that autologous bone marrow derived mononuclear cells and follicular stem cells were both safe and effective for improving resistant alopecia areata and androgenetic alopecia, with no serious adverse events.

This study found that topical minoxidil is more effective than placebo in promoting hair growth in androgenetic alopecia, although cosmetically acceptable results occur only in a subset of patients.

This retrospective study found that adipose-derived stem cell-conditioned media increased hair density and thickness in women with female pattern hair loss over 12 weeks, with no severe adverse effects reported.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This review discusses emerging treatments and mechanisms for alopecia, highlighting potential therapies like janus kinase inhibitors and advances in stem-cell technology, but reports no new experimental results.

This review discusses various methods for obtaining stem cell-derived conditioned media and its applications in disease treatment, finding generally positive results but highlighting the need for standardized production methods.

This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.

This article discusses the development of an evidence-based guideline for treating androgenetic alopecia and reports no new research results.
