This review examines platelet-rich plasma's applications in aesthetic surgery and reports no new clinical results; the authors highlight its growing use and potential as a therapeutic modality.

This study found that Rubus coreanum extract promotes hair growth in mice, but its effects are not due to inhibition of specific enzymatic activities or growth factor expression.

Different substances affect hair and skin cell growth in various ways.

Different substances affect hair and skin cell growth in various ways, with some promoting and others inhibiting cell proliferation.

In this review, retinoids are highlighted as promising agents for promoting scarless skin regeneration by coordinating cellular and molecular processes that suppress fibrosis, enhance re-epithelialization, promote angiogenesis, and enable hair follicle formation, potentially advancing functional skin repair.

This study found that IL-1α promotes hair follicle regeneration and stem cell activation in an age-dependent manner by modulating inflammatory cells and oxidative stress in mice.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

This study found that dermal fibroblast cultures, especially those with higher alpha-smooth muscle actin expression, can be used to produce skin-derived precursor cells, unlike human hair follicle dermal papilla cultures.

This study found that topical Rosmarinus officinalis leaf extract improved hair regrowth in mice and inhibited androgen-associated mechanisms involved in hair loss.

This review discusses the role of defensin peptides in stem cell activation for potential skin rejuvenation therapies and reports no new clinical findings, emphasizing the need for further studies.

This study explored the effects of a new narrow-band red LED light on hair growth in mice, showing potential benefits compared to existing laser therapies.

In this study, topical quercetin was found to stimulate hair follicle growth and promote microvascular regrowth in mice, suggesting its potential for hair regrowth strategies.

In this study, a herbal extract mixture significantly reduced IL-1α gene expression in HaCaT cells, suggesting it may aid in the treatment of nonscarring alopecia.

Cosmeceuticals may benefit skin health but need more research for efficacy and safety confirmation.

This study observed that among male patients who experienced telogen effluvium after platelet-rich plasma treatment for androgenic alopecia, there were elevated levels of TNF-α, androgen receptors, and altered 5α-reductase gene expression, suggesting these factors as potential contributors to this unintended outcome.

This study identified a novel mechanism by which dsRNA-induced TLR3 activation and retinoic acid pathways contribute to new hair follicle formation after deep wounds in mice and suggested a similar potential in humans.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This review discusses recent advances in how proinflammatory cytokines affect epidermal stem cell function during skin wound healing and introduces potential therapies targeting these cells and cytokines.

This review discusses strategies to enhance mesenchymal stem cell therapy effectiveness but reports no new clinical results; it highlights the need for improved consistency and efficacy in MSC-based treatments.

This study found that a newly developed injectable hydrogel combined with human umbilical cord-mesenchymal stem cells significantly accelerated wound healing and reduced inflammation in full-thickness cutaneous wounds.

This article reviews the regulation of androgens in human skin and adrenals, highlighting their role in skin disorders, but reports no new research findings.

This study evaluated the effects of exosome therapy from hypoxia-treated mesenchymal stem cells on a fluconazole-induced alopecia model in rats and found that it significantly reduced TNF-α and increased VEGF levels, suggesting potential as a novel regenerative treatment for alopecia.

This study found that IL-4 VNTR intron 3 and TNF-α (rs1799964) gene polymorphisms do not have a significant association with alopecia areata susceptibility in the Egyptian population.

This study found that Acanthus ebracteatus extract and verbascoside induced dermal papilla cell proliferation and reduced inflammatory cytokine release in vitro, suggesting potential for anti-hair loss applications.

This review discusses new insights into the pathogenesis of alopecia areata related to perifollicular immune and endocrine factors and potential new treatments, but it reports no clinical results.

In this study, prolonged systemic administration of 17β-estradiol in castrated male mice delayed wound healing by inhibiting re-epithelialization and reducing collagen accumulation, with estrogen receptor-α likely mediating this effect.

This study investigated the role of the glycoprotein Thy-1 in hypertrophic scar formation using a murine model, finding that Thy-1 knockdown reduced scar size and encouraged functional regeneration by influencing the p38MAPK signaling pathway under high-tension conditions.

This study found that administering tolerogenic dendritic cell-conditioned medium to dihydrotestosterone-treated mice promoted hair regrowth by modulating the follicular microenvironment, reducing pro-inflammatory cytokines, and activating key signaling pathways, highlighting its potential as a treatment for androgenetic alopecia.

In this study, Eremochloa ophiuroides-derived fractions were found to significantly promote hair regrowth in a mouse model, demonstrating effects comparable to minoxidil and suggesting potential as natural hair growth agents through modulation of follicular activation markers and growth-regulatory factors.
