November 2024 in “Journal of Investigative Dermatology” Changes in scalp bacteria are linked to female hair loss, suggesting new treatment options.
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.
June 2024 in “Current Developments in Nutrition” 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.
April 2024 in “Frontiers in cellular and infection microbiology” 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.
March 2024 in “Nutrients” 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.
November 2023 in “Burns and trauma” This review discusses how the skin microbiome impacts different types of cutaneous wounds, such as acute and chronic, and explores therapeutic strategies targeting the microbiome to enhance healing outcomes.
September 2023 in “Clinical, cosmetic and investigational dermatology” 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.
