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.

CBD can help hair grow by supporting scalp health and reducing inflammation.

This study found that microneedling combined with growth factors significantly improved blood circulation, hair thickness, strand resistance, and psychological well-being in patients with androgenetic alopecia, suggesting this combination as a promising and safe treatment option.

This systematic review found that exosomes and gut microbiota play a significant role in skin regenerative processes, suggesting that gut health is crucial for maintaining aesthetically healthy skin, and probiotic treatments may support traditional dermatological therapies for inflammatory skin diseases.

This case report challenges the traditional view by documenting reversible vision loss following scalp injections of platelet-rich plasma, attributed to an inflammatory or microvascular event, treatable with corticosteroids.

In this rodent study, the researchers found that different hormone therapies affected gut microbiota and goblet cell counts, with notable microbial shifts observed between groups receiving estrogen with and without an orchiectomy, linked to estrogen metabolism.

This study found that Hashimoto's thyroiditis and alopecia areata show distinct gut microbial patterns, with specific microbes like Bacteroides fragilis and Microbacterium sp. T32 potentially linked to autoimmune activity.

This review found that in various dermatological diseases, skin microbiome diversity decreases, with an increased presence of pro-inflammatory strains, and suggests potential of prebiotic treatments as safer alternatives to antibiotics, though further research is needed to confirm efficacy.

In this study, PA-011 extract was reported to promote hair growth and alleviate alopecia areata symptoms in mice by reducing skin inflammation and modulating skin microbiota.

This review highlights that dysbiosis in skin and scalp microbiomes is linked to both atopic dermatitis and androgenetic alopecia, suggesting that microbial composition influences disease progression.

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

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.

Certain gut bacteria may protect against hair loss, while others may increase the risk.

This study suggests that certain gut microbiota may influence androgenic alopecia, potentially acting as protective or risk factors, and indicates opportunities for developing microbiota-based treatments.

This review discusses the use of platelet-rich plasma (PRP) in regenerative plastic surgery and dermatology for hair regrowth and skin revitalization, noting some potential side effects without reporting new clinical results.

In this study, selenium disulfide shampoo was found to reduce dandruff severity and rebalance the scalp microbiome in individuals with all hair types experiencing moderate to severe dandruff, with subjects reporting high satisfaction and good tolerance over a 6-week period.

This study found a significant correlation between aerobic and anaerobic bacteria in the scalp microbiome and female androgenetic alopecia, with notable prevalence differences in specific bacterial groups between affected and non-affected women.

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 study found that chromosomal microarray analysis identified copy number variations in 12% of patients with dysmorphic features and congenital anomalies, demonstrating its potential as a diagnostic tool, especially for rare CNVs and immune deficiency linked to the deletion of CTLA4.

This study of Egyptian patients with alopecia areata found no significant difference in Staphylococcus epidermidis gene expression between patients and healthy controls but reported a negative correlation between Staphylococcus epidermidis expression and the severity of alopecia areata, suggesting potential involvement in disease severity.

This study found that a dietary intervention in dogs alleviated atopic dermatitis symptoms by modulating immune responses and skin microbiome composition compared to baseline, but with similar non-significant trends when compared with a positive control diet.

This study found that a nutritional intervention in dogs led to changes in skin microbiome and immune-related gene expression, with reduced levels of certain fungal pathogens and a potential alleviation of atopic dermatitis symptoms.

In this study, Saudi Arabian women showed moderate awareness of eyebrow microblading, yet many lacked knowledge of hygiene practices, indicating a need for more public education on the procedure's risks and standards.

In this study using female mice, researchers observed that topical application of 20% whale oil was more effective in promoting hair growth compared to a standard 3% minoxidil solution, with additional findings suggesting reduced stress- and inflammation-related responses with whale oil.

This review highlights evidence supporting the potential of blue light therapy as a non-invasive treatment for managing skin and hair conditions by modulating interactions between the skin microbiome and its host.

This study found that certain gut microbiota are linked with androgenetic alopecia, identifying both risk and protective microbial factors, which could inform targeted probiotic strategies for managing AGA.

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 reported that mannan oligosaccharides improved the fur quality, immune response, antioxidant status, and gut microbiota of fur-growing raccoon dogs, suggesting they could potentially replace antibiotics in their diet.

Inhibiting EGFR weakens skin's defense against bacteria.
