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.

In this study, researchers highlighted that PCOS involves not only hormonal imbalances but also significant changes in the microbiome and immune system, which complicate its impact on fertility and suggest potential for new diagnostic and therapeutic strategies.

In this study, patients with scalp seborrheic dermatitis exhibited distinct patterns of allergen sensitization tied to symptoms, impaired skin barrier, and altered microbiota, emphasizing the need to consider allergen exposure, barrier status, and microbial balance when interpreting patch test results.

This study found that patients with scalp seborrheic dermatitis exhibited distinct allergy sensitization patterns linked to skin barrier dysfunction and changes in scalp microbiota, suggesting the importance of context in interpreting patch test reactivity.

In this study, researchers demonstrated that using cyanoacrylate glue effectively reduces microbial contamination in biopsy samples from the skin surface of wild roe deer, offering valuable insights for human hair follicle microbiome research despite the nonhuman model.

In this study, a topical cream containing 3% lactic acid ferment lysate (VHProbi ® MixP) was found to significantly reduce sebum, porphyrin levels, and pore size, while increasing hydration and improving skin texture in participants with oily skin over a 60-day period.

This abstract highlights that while treatments for alopecia areata, like corticosteroids and JAK inhibitors, exist, their effectiveness varies and relapses are common, prompting interest in supplementary therapies.

This research review identified improved outcomes in acne treatment when oral probiotics or topical probiotic-derived formulations were added to standard therapies, with probiotics reducing acne severity and enhancing safety and tolerability compared to treatments such as 2.5% Benzoyl Peroxide and Doxycycline.

In this study, researchers successfully scaled a plant-based shampoo formulation for dry and damaged hair from laboratory to industrial production, maintaining its physicochemical properties and microbiological safety throughout, highlighting the formulation's scalability and the importance of quality control in cosmetic manufacturing.

This paper hypothesizes that gut dysbiosis acts as a key factor in Post-Finasteride Syndrome, potentially explaining its symptom patterns beyond androgen receptor silencing.

This review found that gut microbiota and exosomal microRNAs may collectively impact androgenetic alopecia progression by modulating immune responses and intercellular communication, suggesting new therapeutic possibilities; however, further research is needed to clarify these mechanisms.

This review examines current understanding of how skin microbiota interact with and influence wound healing, highlighting the roles of commensal microorganisms in inflammation resolution, tissue regeneration, and barrier restoration, and discusses potential microbiota-based therapies for improving wound management.

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 study reports that disruptions to the scalp microbiome from invasive cosmetic procedures may contribute to dermatological conditions, and suggests incorporating microbiome assessments and personalized restoration programs into trichological and dermatological practices.

This study developed a rapid ATP assay that effectively measures microbial populations on the skin and tracks changes after microbiome dysbiosis, with findings suggesting that ethanol-cleansed skin takes longer to recover than tape-stripped skin.

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.

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 case study, the combination of microneedling and intradermal therapy was observed to effectively stimulate hair growth and improve hair density in a menopausal woman with androgenetic alopecia, resulting in enhanced self-esteem and cosmetic satisfaction.

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 review reveals that PCOS is consistently linked to gut microbiota dysbiosis, characterized by reduced microbial diversity and shifts in composition, which are associated with various PCOS phenotypes and may present opportunities for microbiota-targeted therapies addressing the disorder's underlying pathophysiological mechanisms.

In this narrative review, dysbiosis was found to potentially influence androgen metabolism and immune response, suggesting that gut microbiota balance may play a role in the prevention and treatment of androgenetic and areata alopecia.

This review explored the relationship between alopecia areata and gut microbiota imbalances, noting potential immune dysregulation due to microbiome alterations. It highlighted promising results from fecal microbiota transplantation in treating alopecia universalis, indicating a need for further research into microbiome-targeted therapies.

This study reviewed literature on the combined use of microneedling and essential oils for treating male androgenetic alopecia, finding that this approach potentially enhances scalp vascularization and hair growth, although controlled clinical trials are needed to confirm these effects and standardize treatment protocols.

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

This study observed that pancreatic cancer-related skin lesions in mice are linked to microbiota imbalances, specifically noting changes in the abundance of certain bacterial genera, which may offer potential diagnostic or therapeutic targets for managing skin complications in humans with pancreatic cancer.

Sampling methods greatly affect skin microbiome data in acne studies.

This study discovered that androgenetic alopecia disrupts the scalp microbiome balance across the whole scalp, not just areas with hair loss, and introduced a microbial index for early detection and severity prediction.

In this research, geography was found to explain more variation in the human skin microbiome than skin type, while host genetics contributed unique microbial structures, highlighting their role in skin microbiome ecology through extensive genomic and metagenomic analyses in a diverse international cohort.

This review article discusses the potential of macroalgae, including red, green, and brown varieties, in treating alopecia by stimulating hair growth in follicles, highlighting findings from 18 articles that suggest different types of algae possess anti-alopecia properties.

This narrative review compiled evidence suggesting that microneedling can effectively and safely improve skin conditions like scars, hyperpigmentation, and aging, provided it is performed correctly, by stimulating collagen production and enhancing topical treatment penetration.
