This study found that the enhancer of zeste homolog 2 (EZH2) may promote hair growth by increasing STK40 expression and facilitating hair follicle stem cell proliferation and differentiation.

This review discusses platelet-rich plasma and microneedling for alopecia areata, reporting promising small-scale findings but no new results, and suggests further trials to determine efficacy and specific disease subtype suitability.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study observed that microneedling induced significant hair regrowth and reduced hyperpigmentation in two Pomeranians with alopecia X, with stable results over 12 months.

This study demonstrated that troxerutin may protect human dermal papilla cells from H2O2-induced damage and suggests potential in treating alopecia by inhibiting ROS-mediated cellular damage.

In this study, transcriptome analysis identified 68 differentially expressed miRNAs in human dermal papilla cells treated with hydrogen peroxide, suggesting they play a significant role in growth arrest and apoptosis.

GABAergic steroid precursors reduce ethanol withdrawal symptoms in certain mice.

Saw palmetto extract can block the enzyme that converts testosterone in pig prostate cells.

This study found that Polygonum multiflorum and Panax japonicum extracts could promote hair regrowth in mice, suggesting potential use as hair tonics.

This study observed that the cutaneous microbiome in psoriasis patients differs both qualitatively and quantitatively from healthy individuals, suggesting a potential link to psoriasis pathogenesis.

This study found that hair follicle stem cells are stiff with high actomyosin contractility, while hair germ progenitors are soft and enlarge during quiescence, influencing hair regeneration; inducing miR-205 reduces contractility and activates regeneration in mice.

This review discusses the use of microbial biosurfactants as a safer alternative to chemical surfactants in cosmetics due to their antibacterial, moisturizing, and low toxicity properties, but it reports no new clinical findings.

This study found that microalgal extract from Botryococcus terribilis exhibited antidepressant-like effects in mice by regulating neuroinflammation and modulating neurotransmitter systems.

This review discusses the role of hair follicle bacterial colonization in immune responses and the pathogenesis of alopecia but reports no new clinical results.

In this study, a home-use microneedle device combined with 5% minoxidil showed potential for enhancing hair growth in pattern hair loss over six months, although the observed improvements in hair count and patient assessments were not statistically significant compared to other treatments.

This commentary reviews the evidence for microinflammation's role in pattern hair loss and suggests that further studies with age- and sex-matched controls are needed to substantiate the findings.

This study suggests that finasteride-loaded polyvinyl alcohol/chitosan microspheres could be a promising embolic agent for benign prostatic hyperplasia, showing effective occlusion and sustained drug release in preclinical models.

This study suggests that abnormal hair cycles in Hr mutant mice may be caused by HR protein overexpression, which down-regulates miR-31 and increases Tgf-β2 expression.

This study found that in Withdrawal Seizure-Prone mice, ethanol withdrawal decreased the sensitivity of GABA A receptors to GABAergic neurosteroids in certain areas of the brain.

This study developed an antimicrobial microneedle patch for delivering apoptotic vesicles to treat infected wounds, which was found to effectively reduce bacterial growth and accelerate scarless healing, including the rapid formation of mature hair follicles in just 8 days, a previously unreported early outcome.

This study found that smaller curcumin nanocrystals (60 nm) enhanced transdermal and transfollicular penetration more effectively than larger sizes, influenced by particle size.

In this study, microneedling with a depth of 0.6 mm, alongside minoxidil, significantly improved hair count and thickness in patients with androgenetic alopecia compared to minoxidil alone, and was more beneficial than a 1.2 mm depth.

This study found that combining microneedling with 5% minoxidil improved hair growth in Chinese men with androgenetic alopecia, possibly through activating the Wnt/β-catenin signaling pathway.

In this study, researchers found that Dicer, but not Tarbp2, plays a crucial role in regulating the growth phase of hair follicles in post-natal mice.

This research reviewed literature to evaluate the role of micronutrients in hair loss and hair growth, examining normal nutrient levels, their role in the hair follicle cycle, and their use in treatments, with data drawn from 92 peer-reviewed articles and reputable health organizations.

This study found that epidermal melanocytes can regenerate hair follicles, whereas non-cutaneous or dermal melanocytes cannot, suggesting two distinct melanocyte lineages with potential implications for melanocyte-related diseases.

This research suggests that both proposed pathways into hair fibers for molecule penetration are valid and complementary, with all fiber structures acting as potential routes for delivering materials.

This review discusses the current and emerging methods for profiling skin microbes to advance our understanding of the microbiome in skin disease, but it reports no new clinical findings.

This review highlights recent advancements in microneedle technology, noting its ability to enhance transdermal drug delivery, biosensing, cancer treatment, and skin disease repair, while emphasizing its potential for improving patient compliance and reducing side effects.

This study found that microneedling monotherapy significantly increased hair count more than topical minoxidil in androgenetic alopecia, with combination therapy of microneedling and minoxidil being even more effective. Further research is needed to evaluate microneedling's safety and efficacy as a monotherapy.
