Fecal Microbiota Transplantation Promotes Hair Growth Through Gut Microbiome and Metabolic Regulation

In this randomized controlled trial, oral intake of the probiotic Latilactobacillus curvatus LB-P9 significantly improved hair luster, elasticity, and participant satisfaction in individuals with mild to moderate hair damage compared to placebo, without significant adverse effects reported.

This study found that in mice, oral administration of Lactilactobacillus curvatus LB-P9 accelerated hair regrowth and increased hair thickness, hair follicle numbers, and dermal thickness, likely by boosting hair growth factor production and dermal papilla proliferation.

This article discusses photobiomodulation as a potential adjunct to hair follicle organoid culture for androgenic alopecia, reporting no new results and suggesting further study is needed.

This study developed a novel liposome-based delivery system for Minoxidil and nitric oxide, which showed promising results in promoting hair regrowth in an androgenetic alopecia model by enhancing transdermal absorption, prolonging skin retention, and reducing inflammation.

In this study, the researchers found that rare genetic variants make a minor contribution to male-pattern hair loss risk, identifying five significant gene associations, including novel genes, and noting a shared basis with monogenic hair loss disorders.

This review summarizes biological links between aging and androgenetic alopecia, particularly focusing on cellular senescence, and discusses potential therapeutic strategies, but reports no new clinical results.

This study found that ingesting Lactobacillus paracasei HY7015 and Lycopus lucidus Turcz. extract promoted hair regrowth and follicle maturation in mice by enhancing cytoprotective effects and growth factor expression.

This study found that androgen receptor signaling is linked to blood vessel regression in the dermal papilla of balding scalp, contributing to hair follicle miniaturization in androgenetic alopecia.

This article reviews potential therapeutic targets and comorbidities associated with male androgenetic alopecia, but reports no new clinical results; further study is needed for comprehensive management.

This study noted that among hospitalized COVID-19 patients, androgenetic alopecia was prevalent, and severe cases were associated with adverse outcomes such as respiratory failure, highlighting a possible link with androgen sensitivity.

This review discusses how modern lifestyle factors affecting gut health may contribute to Alopecia Areata in genetically predisposed individuals, reporting no new results but suggesting the need for long-term interventions.

This review describes minoxidil's hair regrowth mechanism and discusses dermatological applications, but reports no new clinical results, emphasizing the need for regular use and addressing allergic reactions.

This study introduces the concept of a "gut–brain–skin axis" where ingesting a specific Lactobacillus strain in mice may reduce stress-induced skin inflammation and hair growth inhibition.

This study found that the prevalence of androgenetic alopecia in Chinese men was lower than in Caucasian men, similar to Korean men, and most commonly presented as type III vertex.

This study found that 58% of men aged 30-50 had androgenic alopecia, with disease severity increasing with age and many being candidates for medical treatment or hair transplantation.

This article reviews androgenetic alopecia in women, highlighting diagnosis criteria and noting that topical minoxidil is currently the only proven treatment for hair growth; it reports no clinical trial findings.

This study found that finasteride improves scalp hair growth in men with male pattern hair loss by reducing scalp dihydrotestosterone levels, but it did not benefit postmenopausal women with female pattern hair loss.

In this study, the prevalence of androgenetic alopecia among Korean men and women was found to be lower than in caucasians, with Korean men showing more frontal hairline preservation and a higher incidence of 'female pattern' hair thinning.
