This study observed that a combination of micro-needling and low-level light/laser therapy significantly increased hair density in patients with mild to moderate androgenic alopecia, showing an increase of 12 hairs/cm² after 16 weeks, compared to baseline.

This study found that epidermolysis bullosa simplex keratinocytes had impaired mitochondrial activity and more dispersed mitochondrial distribution compared to normal human keratinocytes.

This study found that sphinganine may improve scalp health, hair quality, and reduce hair loss in males, potentially due to increased antimicrobial peptide levels and inhibition of 5-α-reductase.

This study observed that minoxidil-loaded nanoparticles significantly enhanced skin penetration and hair regrowth in mice within three weeks, without ethanol and propylene glycol, suggesting they are a promising delivery method for treating hair loss.

This study reported that newly developed RADA16-I peptide hybrids, with active motifs like GHK and KGHK, demonstrated improved wound healing in a mouse skin injury model without cytotoxicity, suggesting they might be effective scaffolds for tissue engineering and regeneration.

In this study, exosome-loaded hydrogels derived from skin precursor cells significantly improved wound healing in diabetic rats by enhancing angiogenesis, reducing inflammation, and promoting tissue repair.

In this study, porcine collagen acellular dermal matrix scaffolds combined with mice platelet-rich plasma were associated with increased hair density and follicle regeneration in mice with alopecia, suggesting a potential therapeutic approach.

This study found that hypoxic preconditioning of nanofat from donor mice reduced its vascularization capacity in vivo, suggesting that this approach cannot currently enhance nanofat's regenerative potential.

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 review highlights pigment epithelium-derived factor's roles in ageing and development, focusing on its antioxidant functions and support of stem cell survival, but reports no new experimental results.

In this systematic review and meta-analysis, researchers found that exosome therapies significantly improved facial wrinkles by 20.2% and enhanced hair density and thickness by 23.6% and 18%, respectively, despite challenges in generalizability due to study heterogeneity and nonstandardized protocols.

This review explores low-level light therapy's potential as a noninvasive treatment for various forms of alopecia, noting its promising results in hair regrowth and density but highlighting the need for standardized protocols and further research.

This review identified significant effects of photobiomodulation therapy on pain reduction in burning mouth syndrome, disability in knee osteoarthritis, and fatigue in fibromyalgia, but noted that most outcomes had low-to-moderate certainty of evidence, indicating a need for further high-quality trials.

This systematic review found that topical adenosine may increase hair thickness and density while reducing hair loss, but the strength of evidence is low due to issues with trial design and sample size.

In this study, researchers found that a shampoo containing caffeine and adenosine significantly altered the scalp microbiome and lipidome in subjects with hair loss over 12 weeks, which may suggest a role for these compounds in enhancing anti-hair loss processes.

This study concluded that stromal vascular fraction and topical minoxidil both improved hair characteristics in male and female patients with androgenetic alopecia, but SVF offered a more satisfactory treatment experience.

In this study, conducted at the Jordan Clinic in Tehran, smokers and alcohol users who underwent hair transplantation had significantly worse outcomes, such as lower hair density and growth, compared to non-smokers and non-drinkers, highlighting the negative impact of these lifestyle factors on treatment efficacy.

In this multicenter observational study, researchers found that using micrografts with human follicle mesenchymal stem cells increased hair density significantly in both male and female patients with mild to moderate androgenic alopecia after 12 months, suggesting a viable alternative for hair regrowth.

In this study, injecting foreskin-derived mesenchymal stromal cell exosomes into the scalps of men with androgenetic alopecia significantly increased hair density and patient satisfaction without side effects over a 12-week period.

This systematic review reports positive outcomes for platelet-rich plasma in aesthetic dermatology applications like skin rejuvenation, hair restoration, wound healing, and fat grafting, but highlights the need for standardized protocols in future research.

This study found that three sessions of injectable platelet-rich fibrin (i-PRF+) significantly improved hair follicle density, hair volume, and thickness, as well as patient satisfaction in women with female pattern hair loss, with only minor self-limited adverse effects reported.

This review found that exosome use in aesthetic plastic surgery shows promise in areas like skin rejuvenation and hair restoration, with laboratory studies indicating enhanced outcomes, but clinical evidence remains largely anecdotal, and no exosome-based products have FDA approval.

This study found that transplanted hair follicle-associated pluripotent stem cells in mice differentiated into keratinocytes and stimulated hair growth by producing mature hair shafts.

Using micrografts with stem cells and platelet-rich plasma can safely and effectively help regrow hair.

This review concludes that platelet-rich plasma treatment is effective for androgenetic alopecia, with recommendations for a specific volume, frequency, and duration of therapy for optimal results.

This study investigated the effects of GFC with FGF5s and NMN at a depth of 0.8 mm using a microneedle for treating hair loss, but the abstract provides no measurable results.

This article reviews the complex process of wound repair, emphasizing recent microarray studies and proteomic analyses, but reports no new clinical results.

Keratin filaments are crucial for cell structure and protection, with ongoing discoveries about their genes and functions.

This review discusses the history and development of keratin biomaterials for biomedical uses, highlighting their biological activity and biocompatibility, and provides no new research findings.

This study found that platelet-rich plasma injections significantly increased hair count and density in patients with male pattern hair loss without major side effects, suggesting it may be a safe and effective treatment option.
