This study found that women who wear the hijab have a different scalp microbiome composition compared to those who do not, with specific bacteria and fungi more prominent in each group, suggesting a higher susceptibility to seborrheic dermatitis among hijab wearers.

This review discusses the potential of gut microbiota-derived exosomes as drug delivery systems and reports no new clinical results; the authors highlight their promise for precision medicine.

This review discusses the role of the skin microbiome in maintaining health and modulating atopic dermatitis, emphasizing the need for novel therapeutic strategies, but reports no new clinical results.

In this study, researchers using Mendelian randomization found a potential causal relationship between the gut microbiome and alopecia areata, with 16 gut microbial taxa showing links to the condition, though reverse causation results were not statistically significant.

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.

In this study, germ-free male mice showed altered levels of certain neuroactive steroids in the brain and periphery, suggesting microbiota may influence neuroendocrine pathways that support brain functioning.

Certain bacteria may influence alopecia areata risk, but skin bacteria don't mediate gut-skin effects.

This study found that enhancing quercetin bioavailability with EubioQuercetin significantly improved external aging signs in mice and influenced gut microbiota and intestinal gene expression, suggesting potential modulation through the gut microbiota–intestinal barrier axis.

The study found that enhancing quercetin bioavailability with EubioQuercetin may amplify its anti-aging effects in mice by modulating the gut microbiota and improving intestinal barrier function.

This study examines how skin microbiota and the gut-skin axis affect acne development, aiming to reveal mechanisms that could inform future treatment strategies for acne and other inflammatory skin conditions.

The researchers reported that platelet-rich plasma treatment increased hair growth in androgenic alopecia patients, potentially by altering scalp microbiota composition, including increased Cutibacterium and decreased Staphylococcus and Lawsonella.

This study will explore skin and hair characteristics of pregnant women and their newborns, examining the relationships between these factors and the newborns' skin maturation over time.

This study suggests a potential genetic link between gut microbiota and androgenetic alopecia, identifying specific microbial taxa associated with either increased or reduced risk.

This review discusses neuroimmune communication in skin disorders and peripheral neuropathic pain, highlighting the complex interactions between sensory neurons and immune cells; it reports no new clinical results but suggests potential future therapies.

This study using high-performance liquid chromatography reported that mice with more diverse gut microbiota had higher levels of specific compounds in hair compared to those with less diversity, with stress affecting certain plasma levels.

In this review, researchers synthesized contemporary findings about the human skin microbiome's influence on conditions like acne, aging, and hyperpigmentation, highlighting the potential of microbiome-informed strategies and treatments such as postbiotics and probiotics to improve dermatological outcomes.

This study demonstrated that Periplaneta americana extract significantly promoted hair regeneration in depilated mice by enhancing superoxide dismutase activity, upregulating vascular endothelial growth factor, modulating the FOXO/PI3K/AKT pathway, and restoring skin microbiome balance, suggesting its potential as a novel therapeutic candidate for alopecia.

This review provides a comprehensive guide to the human microbiome and reports no new experimental results; it highlights the impact of modern lifestyles on microbial homeostasis and the necessity of conservation efforts.

This study found that patients with alopecia areata had a significantly different gut microbiota composition compared to healthy controls, suggesting possible microbiota involvement in the disease's pathogenesis.

This review explores the connection between the gut-skin axis and the development of dermatological conditions like atopic dermatitis, psoriasis, alopecia areata, and acne, and discusses the potential of probiotics in reshaping the microbiome to alleviate these skin issues.

This review highlights how wound microbiota, particularly bacteria like Staphylococcus epidermidis and Staphylococcus aureus, significantly influences wound healing dynamics and suggests potential clinical applications through microbiota manipulation.

This study found that bacterially induced metabolic changes in stem cells can enhance skin and hair follicle regeneration in both mice and humans, suggesting potential strategies for improving recovery after injury.

This study found that piglets' rapid growth during nursery and lactation was linked to changes in microbiota composition and increased cortisol conversion, highlighting critical early life factors influencing adult microbiota establishment.

This study found that omega-6 and saturated fatty acid-enriched diets promote weight gain and certain skin changes regardless of gut microbiota, while omega-3 diets limit adiposity and affect skin in a microbiota-dependent way in mice, highlighting a diet–microbiota–lipid relationship in skin health.

This study found that individuals with seborrheic alopecia had significant disruptions in their scalp microbiome, marked by imbalances in certain bacteria and fungi, and that a 12-week herbal shampoo intervention helped restore microbial diversity and improve clinical symptoms.

This study observed that in young women, the scalp microbiota is influenced by sebum level, barrier sensitivity, and lifestyle factors, with barrier sensitivity emerging as a key factor, offering insights for further research into scalp health and conditions.

This research identified unique gut microbiota patterns in alopecia areata patients, with potential as diagnostic biomarkers and suggesting avenues for microbiota-focused therapies.

In this preclinical study, PA-011 derived from Periplaneta americana showed significant hair regrowth effects in androgenetic alopecia mouse models by inhibiting inflammation and oxidative stress, activating hair follicle stem cell proliferation, and normalizing skin microbiota, suggesting promise as an AGA treatment.

This study found that individuals with Alopecia Areata had distinct gut microbiome characteristics, including reduced species richness and specific microbial biomarkers, suggesting a potential link with oxidative stress.

This study found that individuals with androgenetic alopecia had higher scalp microbiome diversity and more complex scalp-gut microbiome networks than those without, suggesting a link between skin-gut microorganisms and hair loss development.
