This study found that platelet-rich plasma injections led to improvements in hair counts, thickness, and strength in patients with androgenic alopecia, showing promise as an effective treatment with no major adverse effects.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

This study reported that a novel trilayer electrospinning wound dressing can improve the wound microenvironment and accelerate repair in abdominal wall defects by facilitating directional biofluid transport and reducing inflammation.

The authors concluded that while PRP is a promising and well-tolerated treatment for early to moderate knee osteoarthritis, standardizing preparation protocols, patient selection, and outcome reporting is crucial to enhance comparability and inform clinical practice.

In this review, cellulose-based nanofibers are highlighted for their potential in wound care, given their biodegradability, biocompatibility, and ability to enhance antimicrobial properties and drug delivery in wound dressings through modern fabrication techniques like electrospinning.

This study found that both microneedling and microneedling with platelet-rich plasma improved hair thickness and density in male pattern alopecia, but no additional benefit was observed with the addition of platelet-rich plasma.

This review highlights the promise of small extracellular vesicles (sEVs) as biomarkers for sepsis, emphasizing their potential to improve early detection and guide therapeutic decisions by reflecting the immune status and pathogen presence in patients.

This review highlights the potential of self-powered nanogenerators in revolutionizing biomedical devices by using biomechanical or environmental energy, focusing on applications like regenerative hair growth, drug release patches, and electronic skin while evaluating challenges such as energy efficiency and biocompatibility.

This study found that the meropenem-loaded spanlastic formulation showed strong potential as an effective topical therapy for bacterial skin infections in non-diabetic mice, demonstrating superior therapeutic activity and wound healing compared to free meropenem.

This study found that platelet-rich plasma significantly improved hair density and thickness compared to monofilament thread implantation in treating androgenetic alopecia.

In this study conducted at Al-Azhar University Hospital, 60% of patients with localized alopecia areata responded to treatment with autologous platelet-rich plasma, with 89% of responders showing substantial improvement, suggesting PRP as an effective treatment option for this condition.

This review examines the definition, classification, mechanism, clinical efficacy for hair regrowth, and potential adverse effects of platelet rich plasma, but does not present new experimental results.

This review reports that platelet-rich plasma may be more effective for musculoskeletal conditions when prepared with high platelet doses and low leukocyte content, but further trials are needed to confirm optimal formulations.

This study found no significant difference in the severity of alopecia areata between treatments with platelet-rich plasma and triamcinolone acetonide; further high-quality trials of PRP are needed.

This study reports on the clinical and dermoscopic diagnosis process for androgenic alopecia in patients at Zagazig University Hospitals but includes no new treatment findings.

This review outlines the optimization of platelet concentrates for hair loss treatment and suggests extracellular vesicles as a key future element, aiming to advance point-of-care regenerative therapies despite the need for a unified framework and further research on underlying mechanisms.

In this split-scalp study, researchers observed that combining fractional CO2 laser and PRP treatment was significantly more effective in improving hair parameters in women with female pattern hair loss than using each intervention alone or placebo.

In this study, PRP therapy did not show significant effectiveness in treating androgenetic alopecia in patients over a 6-month period, with 45% of participants reporting no improvement in hair growth, although adverse effects were minimal and non-serious.

This study found that platelet-rich plasma therapy may offer a simple and cost-effective treatment option for androgenetic alopecia in men, with around 70% of participants showing mild to excellent improvement.

This review suggests that platelet-rich plasma may be a promising treatment for immune-mediated alopecias, including alopecia areata and primary cicatricial alopecias, but definitive recommendations are limited due to insufficient high-quality evidence.

This study found that platelet-rich plasma therapy significantly improved hair density, diameter, and reduced inflammation in androgenetic alopecia patients compared to placebo, though individual responses varied.

This study suggests that autologous platelet concentrates may improve inflammatory activity, disease control, and hair regrowth in primary cicatricial alopecia, but the evidence is limited by small sample sizes and study quality.

This review discusses the varied applications of platelet-rich plasma in plastic surgery and reports mixed evidence on its efficacy, indicating a need for more standardized, controlled trials.

This review highlights that various components of "skin boosters," such as exosomes and hyaluronic acid, may have potential applications beyond aesthetics, acting as adjunct therapies for improving skin integrity and promoting tissue regeneration, though more research is needed to support their use as primary treatments.

This study critically reviewed recent evidence (2020–2025) on treatments like platelet-rich plasma, photobiomodulation, stem cells, and exosomes for androgenetic alopecia, finding emerging but limited efficacy data and emphasizing the need for standardized protocols to enhance transparency and patient safety.

In this study, injections of PRP and MZT products significantly improved hair thickness, density, and count in AGA patients over six months, with variability observed in the extent of improvement between different formulations.

This meta-analysis suggests that combining platelet-rich plasma with minoxidil enhances hair growth and patient satisfaction more effectively than using either treatment alone for androgenetic alopecia.

This study found that platelet-rich plasma therapy may effectively treat androgenetic alopecia and could potentially replace topical minoxidil, offering promising results in terms of hair growth and patient satisfaction.

This review highlights the therapeutic potential of plant-derived exosomes, noting their larger size compared to animal-derived exosomes and usefulness in targeted drug delivery and inter-kingdom communication. It summarizes existing research on their biogenesis, characterization, and engineering for drug delivery, indicating significant opportunities for biotechnological advancements.
