Reduced AhR signaling in HS tunnels leads to persistent inflammation and microbial imbalance.

Changes in scalp bacteria are linked to female hair loss, suggesting new treatment options.

This study found that treatment with the synbiotic SIM01 significantly alleviated multiple symptoms of post-acute COVID-19 syndrome compared to placebo, suggesting potential management benefits through gut microbiome modulation.

This theoretical paper proposes that a subset of Post-Finasteride Syndrome cases may be driven by a gut-derived toxic process involving hydrogen sulphide-producing bacteria, suggesting that the small intestinal microbiome could be a potential target for treating this condition.

This study identified specific gut bacterial pathways that may serve as potential therapeutic targets for managing androgenetic alopecia in obese individuals.

This study found that sodium butyrate, a metabolite from the HF microbiome, significantly delayed catagen onset and promoted key physiological processes in cultured human hair follicles.

In this study, the researchers found that a 28-day topical treatment with a postbiotic ferment complex notably altered the scalp microbiome in women with sensitive scalps, increasing certain bacterial species and decreasing others, while also reportedly alleviating symptoms of sensitive skin syndrome in all participants.

This study observed that bacterial communities on scalp hair collected through non-invasive swabbing showed similar diversity and composition to those obtained by cutting or removing hair, suggesting that swabbing is an effective method for microbiome analysis on hair.

In this study on diabetic wound healing in mice, Calvatia gigantea extract accelerated wound recovery, reduced inflammation, and improved the microbiome's diversity, particularly enhancing Escherichia–Shigella bacteria presence.

This study found that Bacillus subtilis strain Ydj3 significantly enhanced sweet pepper seed germination, fruit quality, and rhizosphere bacterial composition, including increased yield and vitamin C content, in a commercial greenhouse setting.

This study reported that shallot extract showed strong antimicrobial activity, and supplementation with shallot powder may enhance broiler chicken growth, immune response, and microbiome balance.

This study observed a microbial shift on the scalp of Alopecia areata patients, characterized by an increase in Propionibacterium acnes and a decrease in Staphylococcus epidermidis, compared to healthy controls.

This research underscores the critical role of the human microbiome in health, highlighting potential therapeutic benefits of interventions like fecal microbiota transplantation and probiotics for conditions linked to microbiome dysbiosis, such as metabolic disorders and inflammatory diseases.

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 explored the associations between the skin microbiome and metabolome in groups LS, NL, and HC, suggesting potential new pathways for understanding scalp involvement in AD patients, which could improve management strategies.

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 paper proposes a novel theory that certain symptoms of Post-Finasteride Syndrome may be caused by an overgrowth of hydrogen sulphide-producing bacteria in the small intestine, which acts as a mitochondrial toxin, with implications for treatment targeting the gut microbiome.

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.

In this study, lifelong barley intake in SAMP8 mice was associated with extended lifespan, improved aging-related phenotypes, and beneficial shifts in the intestinal microbiome.

This review discusses the role of gut microbiota in autoimmune and immune-mediated dermatological conditions like lupus and psoriasis, but reports no new clinical results; the authors emphasize the need for further study into microbial signatures and treatments.

This pilot study explored a new method using laser-capture microdissection and 16S rRNA gene sequencing to analyze the human scalp hair follicle microbiome more accurately, revealing region-specific variations in microbial diversity and abundance.

This scoping review suggests there is a relationship between polycystic ovarian syndrome and vaginal microbiome dysbiosis, potentially linked to decreased Lactobacillus and increased pathogenic species.

This study found that disruptions in the skin microbiome, known as dysbiosis, play a significant role in various skin conditions, including atopic dermatitis, psoriasis, acne, rosacea, skin cancer, and impaired wound healing, by altering immune responses and barrier functions.

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 review discusses how functionalized hydrogels can modulate the microbiome to aid tissue regeneration and infection control, highlighting their potential to deliver therapeutic agents effectively and support beneficial immune responses.

This study shares preliminary findings that roxithromycin treatment tendentially increased hair shaft production and altered the hair follicle microbiota in human hair ex vivo, with substantial inter-individual differences observed.

In this study, patients with alopecia areata displayed altered scalp microbiota compared to healthy controls, and treatment with JAK kinase inhibitors largely restored these microbial changes, providing insights into the potential role of the skin microbiome in alopecia areata.

In this research, authors found that skin-resident ILCs regulate sebaceous gland function and microbial balance, emphasizing an immune-epithelia system that supports host-microbe symbiosis.

This review highlights how disruptions in the host microbiome can worsen inflammation and infection-related pathology, while it remains unclear exactly how the microbiome helps resolve such inflammation, potentially impacting future treatments for infection-induced inflammatory diseases.

In this study, feeding Gymnocypris eckloni with Flammulina velutipes residues enhanced foregut morphology and beneficially altered gut microbiota, highlighting potential improvements in intestinal health for aquaculture use.
