In this preliminary study, HBOT appeared to improve subjective measures of hair and scalp health in healthy adults, but objective changes in follicle density and hair properties were not statistically significant.

In this study, the researchers found that a keratin hydrogel filler in nerve conduits led to earlier Schwann cell migration and improved cellular behaviors compared to other fillers in a rat sciatic nerve model.

This study found that injecting xeno-free, three-dimensional cell masses from human adipose-derived stem cells improved blood perfusion and preserved limb function in mice without causing tumors or toxicity, suggesting potential for treating severe ischemic diseases.

This study found that Satura Rosta Balm exerts a cytotoxic effect under oxidative stress and may trigger regeneration through autophagic pathways, despite not promoting proliferation or stress resistance in human cells.

This study reviewed recent developments in cell therapy for hair loss, finding adipose-derived stem cells and dermal sheath cup cells as promising alternatives to conventional treatments, albeit with varying effectiveness and challenges in trichogenecity and hair growth outcomes.

This study observed that M. domestica larva-derived chitosan and gut extracts enhanced wound healing and collagen deposition in both immunocompetent and immunosuppressed mice, indicating potential benefits for combined therapy.

This study found that low-level laser therapy accelerates skin regeneration in gamma-irradiated mice and enhances the biostimulatory effect on hair follicles.

In this study, low-intensity ultrasound was investigated as a noninvasive method for promoting hair regrowth in androgenetic alopecia using C57BL/6 male mice, revealing that specific frequencies and intensities can safely enhance hair regrowth compared to controls by optimizing mechanical effects without causing unsafe cavitation.

In a rodent study, a flexible, self-powered triboelectric nanogenerator wound patch combining electrostimulation and photothermal effects was found to efficiently accelerate wound healing and hair follicle regeneration.

This study found that treatments with adipose-derived stem cell secretome and minoxidil significantly improved hair growth in androgenetic alopecia, with the combination therapy showing the greatest improvement over 12 weeks.

In this study, researchers observed that applying negative pressure to nude mice led to a significant increase in hair follicle growth and angiogenesis, suggesting potential for hair regeneration through mechanisms involving SOX-9, LHX-2, and β-catenin mediation.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This review discusses the paracrine function of mesenchymal stem cells in tissue regeneration and repair, focusing on secreted bioactive substances and their role under different microenvironments; it reports no new clinical results.

This review discusses how using hydrogels as a three-dimensional culture platform for mesenchymal stem cells might affect the production of extracellular vesicles, highlighting challenges in standardization and opportunities to boost EV yield via combined hydrogels and bioreactor methods.

This review discusses the therapeutic effects of stem cell therapy in various diseases and emphasizes the need for controlled differentiation and further large-scale trials, but reports no new findings.

This study found that activating the PI3K/Akt signaling pathway in dermal papilla cells enhances their hair-inducing capabilities, suggesting potential strategies for hair regenerative medicine.

In this study, conditioned medium from genetically engineered mesenchymal stem cells significantly improved wound healing, re-epithelialization, hair follicle formation, and angiogenesis in diabetic mice, suggesting a promising new approach for diabetic ulcer care.

This study found that a collagen patch made with fibroblast-derived extracellular matrix (fdECM) extracted from human lung fibroblasts enhanced wound healing by promoting wound contraction, angiogenesis, and skin remodeling in full-thickness skin wound models, including those with diabetic ulcers.

Keratin-based hydrogels from human hair improve wound healing effectively.

This study found that topical Linum usitatissimum gel significantly enhanced wound healing and tissue regeneration in rat models, with increased collagen synthesis and vascularization compared to controls.

This study found that AiQingHua oil improved microcirculation and promoted hair regeneration in mice with testosterone-induced alopecia.

This study found that electric shaving was the most effective and safest method for preoperative hair removal in mice, compared to depilatory cream and sodium sulfide, which negatively affected wound healing.

This study found that exosomes derived from human adipose stem cells significantly enhanced the proliferation and migration of dermal papilla cells compared to those from platelet-rich plasma, suggesting potential benefits for hair loss treatment.

This study found that a 25% Pistacia atlantica leaf extract ointment significantly enhanced wound healing in rats, performing comparably to phenytoin in terms of epithelialization, angiogenesis, and collagen deposition, with reduced inflammation, suggesting it may be a safe and effective alternative for wound management.

This study found that Glehnia littoralis and Andrographis paniculata may support hair growth by protecting against oxidative stress and increasing VEGF and Wnt/β-catenin signaling in human hair follicle dermal papilla cells, with enhanced effects when combined.

This study found that decreased COL17α1 expression in aging mouse skin is associated with reduced proliferation of epidermal stem cells and may contribute to thinner epidermis and slower wound healing.

This review examines the efficacy of platelet-rich plasma for treating hair loss, highlighting the lack of standardized protocols for PRP preparation and delivery and reporting no new clinical results.

This study tested a natural hair dye made from papaya seed extract, celery leaf, and avocado, finding color change in animal hair but also noting tissue changes like hyperkeratosis.

This study found that topical application of copper (II) albumin complex improved healing signs in rats with full thickness thermal burns, enhancing antioxidant, anti-inflammatory, and pain modulating effects.
