This narrative review examines the technological advancements and clinical applications of liquid injectable platelet-rich fibrin (i-PRF), discussing its use across regenerative periodontology, sports medicine, and more, as well as its potential as a drug delivery system.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

This study found that conditioned media derived from dental pulp stem cells improved hair growth in 75% of men with androgenic alopecia, with positive results observed regardless of disease severity or the use of a dihydrotestosterone inhibitor.

This study found that injecting drug users attending an oral substitution therapy center often experience skin lesions, which negatively impact their psychosocial health and quality of life.

This review examines clinical trials on low-level laser therapy for pattern hair loss but reports no definitive conclusions, highlighting the need for more controlled studies to resolve uncertainties.

This study found that distinct low-threshold mechanoreceptors innervate different hair follicle types in mice, suggesting that these follicles serve as unique mechanosensory structures in touch perception.

This meta-analysis estimated that around 80% of patients who had COVID-19 experienced at least one long-term symptom, with fatigue being the most common reported effect.

This study found that peripheral clock genes, particularly BMAL1 and Period1, modulate human hair follicle cycling, suggesting their potential as therapeutic targets for affecting hair growth.

The researchers found that plant extracts from Papaver rhoeas L., Clitoria ternatea L., and Carthamus tinctorius L. are effective natural cosmetic dyes, offering intense and stable colors without cytotoxicity.

This study suggests that IL-1β produced by dermal papilla cells, regulated by protein kinase C, may inhibit human hair follicle growth through paracrine signaling.

This study reported that tryptanthrin, a compound found in indigo naturalis, effectively suppresses non-melanoma skin cancer in mice by reducing inflammation, inhibiting cell proliferation, and blocking specific signaling pathways associated with tumor growth.

In this study, silencing P-cadherin in human scalp hair follicles reduced melanogenesis and associated protein expression, suggesting P-cadherin is crucial for normal hair pigmentation via GSK3β-mediated Wnt signaling.

This study found that miR-150 enhances the resolution ability of endothelial progenitor cells in venous thrombosis by promoting cell differentiation and proliferation through specific gene regulation pathways.

This study found that hair follicles can be used to generate pluripotent stem cells, which successfully differentiate into keratinocytes and may improve hair regeneration and grafting for medical applications.

This study found that Trichosanthes kirilowii extract significantly enhances keratinocyte proliferation and wound healing in vitro and in vivo, suggesting its potential as a wound-healing component.

This report describes the clinical presentation of Papillon-Lefèvre syndrome in two brothers and reviews the related literature, without providing new clinical outcomes.

Certain tyrosine kinases may regulate hair growth and could help develop hair loss treatments.

This study developed a genetic toolbox to engineer Cutibacterium acnes for dermal applications, successfully creating a strain that secretes antioxidants to reduce oxidative stress in a UV stress model.

This study found that a high sesquiterpene C. aeruginosa extract significantly reduced axillary hair growth in women compared to placebo with no apparent adverse effects.

This study found that aliphatic ester moieties in 16-formyl-17-methoxy dehydroepiandrosterone derivatives increased their potency as 5α-reductase type 2 inhibitors in vitro compared to finasteride.

This study found that mice lacking the CXCR2 receptor regenerated tissue scarlessly in various injury models and that administering plasma or G-CSF from these mice to wild-type mice also reduced scarring, suggesting potential therapeutic strategies to improve human skin wound healing.

This article describes adult female acne as a complex condition affected by genetic, hormonal, and environmental factors, with hormonal therapies highlighted as particularly valuable for treatment.

In this study, researchers found that specific treatment parameters disrupted follicles and sebaceous glands, damaging the bacteria Cutibacterium acnes and promoting follicular remodeling, which may improve both inflammatory and noninflammatory acne lesions.

This study found that an 8-week supplementation with specific probiotic strains improved hormonal markers and oxidative stress while decreasing inflammation in women with PCOS, although clinical symptoms like acne and hirsutism showed no significant improvement compared to the placebo group.

This review examines the phytochemistry and pharmacology of Emblica officinalis, highlighting its traditional and documented medicinal uses, but reports no new clinical findings.

This symposium discussed recent advances in understanding skin as a sensory organ, emphasizing the interactions between itch, pain, and touch pathways and highlighting potential therapeutic targets.

This study investigated the presence of Helicobacter pylori and Chlamydia trachomatis in women with PCOS, finding no significant association between these infections and PCOS, while also reporting higher inflammation markers and related health issues in the PCOS group compared to controls.

This review explains that dysregulated sebum secretion and composition contribute to acne and impaired skin barriers while highlighting factors like diet and hormones affecting sebaceous activity, and identifies novel molecular targets and model systems for future therapeutic developments.

In this study, researchers found that among patients with severe alopecia areata, a change in SALT scores of 42 or 43 points represents meaningful improvement, highlighting the need to consider individual treatment goals beyond conventional low SALT score targets when assessing treatment benefits.

This study found that Cerasus serrulata extracts, when obtained through specific methods, demonstrate significant antioxidative and antibacterial properties, as well as potential anti-alopecia effects in a mouse model, potentially making them useful supplements for these purposes.
