This study found that platelet lysate produced higher follicular regeneration in hair restoration surgeries compared to activated PRP and saline, with significant gains in both follicular unit and hair density.

This study found that mesenchymal stem cells, especially when injected intradermally, significantly accelerated wound healing in rats compared to chitosan treatment.

This study found that platelet-rich plasma was effective for hair regrowth in women with androgenic alopecia, though less so than minoxidil, but it was associated with improved quality of life responses.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This research review found that platelet-rich plasma treatment generally produced successful hair regrowth in both androgenetic alopecia and alopecia areata, despite study differences that limited direct statistical comparison.

This review discusses cross-sex hormone therapy for managing gender dysphoria in transsexual individuals and reports no new clinical results; it highlights the need for education and culturally sensitive training for healthcare professionals.

This review discusses the potential mechanisms of platelet-rich plasma in facial rejuvenation and reports no new clinical results, indicating a theoretical basis for its use in tissue regeneration.

This review highlights recent findings on blood-derived autologous therapies for skin repair and wound healing but presents no new clinical results, emphasizing future challenges and prospects in regenerative dermatology.

This study concluded that platelet-rich plasma injections significantly improved hair density, thickness, and scalp inflammation in both male and female pattern hair loss, with better outcomes in lower-grade cases.

This study found that autologous platelet-rich plasma was associated with increased hair density in people with pattern hair loss, but with considerable variability and unclear risks of bias.

This review discusses platelet-rich plasma for androgenic alopecia and reports beneficial effects on hair density and quality, but suggests more rigorous studies are needed for conclusive evidence.

This review found that among emerging technologies for skin anti-aging, stem cell therapies using recipient chimerism might be more beneficial than CRISPR-Cas9 and other current innovations, though further studies on safety and efficacy are needed.

In this study, researchers administered eight sessions of intradermal injections containing growth factors into the scalp of 1000 patients, reporting a significant reduction in hair fall in 83% of participants and increased total hair count and shaft diameter, with promising tolerance and safety.

This study found that gelatin microspheres loaded with platelet-rich plasma enhanced wound healing in rats by improving inflammatory and angiogenic responses compared to untreated wounds or PRP alone.

This review discusses the potential use of platelet-rich plasma for treating alopecia areata but reports no new experimental findings, noting the need for standardized protocols and larger studies to evaluate its efficacy.

This systematic review and meta-analysis found that platelet-rich plasma treatments improved hair density and thickness in people with androgenetic alopecia, without serious adverse effects.

This study suggests platelet-rich plasma may be more effective than other non-surgical treatments for male androgenetic alopecia, while low-level laser therapy ranks highest for women; however, the evidence quality was low.

This study demonstrated that using morphometric and 3D reconstruction software to evaluate scalp biopsies in non-cicatricial alopecias may be feasible and sensitive for detecting subtle follicular changes.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

This study found that combining platelet-rich plasma therapy with minoxidil was more effective in treating androgenetic alopecia in men than either treatment alone.

The study found that a specific signaling pathway helps skin wounds heal faster but may lead to larger scars.

This abstract discusses platelet-rich plasma therapy for patterned hair loss but provides no new clinical results, suggesting further research is needed to determine its effectiveness.

This study found that trichoscopy aided in assessing treatment responses for patchy alopecia areata, with both intralesional corticosteroids and platelet-rich plasma showing effectiveness, but only PRP significantly improved patient symptom impact scores.

This review highlights new treatment options for hair restoration, including platelet-rich plasma and stem cell therapy, which have shown efficacy in increasing hair count and density for androgenetic alopecia and alopecia areata, but presents no original clinical data.

This study found that platelet-rich plasma may effectively increase hair follicle numbers in men with androgenetic alopecia, but changes in hair thickness plateaued after the second injection.

This review outlines recent research on platelet-rich plasma, alone or combined with other therapies, for managing hair loss disorders, and discusses future prospects without reporting new clinical findings.

This review discusses the use of non-transfusional hemocomponents in surgical procedures for tissue regeneration and reports no new empirical findings.

Platelet Rich Plasma (PRP) shows promise for tissue repair and immune response, but more research is needed to fully understand it and optimize its use.

This study observed that Cyp27b1−/− mice exhibited growth and skeletal abnormalities similar to those of Vdr−/− mice, despite differences like the development of alopecia in Vdr−/− mice, suggesting that 1α,25D3 may directly influence chondrocyte proliferation and differentiation.

In this study, minoxidil and human platelet lysate affected gene expression related to hair growth signaling pathways in mouse hair follicle cells.
