Characterization of Distinct Microbiota Associated With Androgenetic Alopecia Patients Treated and Untreated With Platelet-Rich Plasma

This review discusses the role of hair follicle bacterial colonization in immune responses and the pathogenesis of alopecia but reports no new clinical results.

This study suggests that Lindera strychnifolia root extract may help restore a healthy microbial balance on the scalp in men with androgenetic alopecia after 83 days of treatment.

This systematic review and meta-analysis found that platelet-rich plasma treatments improved hair density and thickness in people with androgenetic alopecia, without serious adverse effects.

This review explores the hair follicle microbiome's interaction with the immune system, discussing its potential clinical implications for scalp health and disease but reports no new clinical results.

This study observed that dandruff in Indian women is associated with a distinct scalp microbiome, including specific bacterial and unknown Malassezia species, with implications for nutrient homeostasis and cell-host adhesion pathways.

This study found that low-level laser therapy was the most effective non-surgical treatment for androgenetic alopecia, although the overall quality of evidence supporting various therapies was generally low.

This review evaluates dihydrotestosterone's role in androgenic alopecia and proposes a model suggesting that chronic scalp tension and inflammation contribute to hair follicle miniaturization, identifying fibrosis, calcification, and tension as treatment targets.

This systematic review and meta-analysis found that minoxidil, finasteride, and low-level laser light therapy significantly improve hair growth in men with androgenetic alopecia, while minoxidil is also effective for women, compared to placebo.

This review discusses various classification systems for patterned hair loss in both sexes and reports no new clinical findings, highlighting the Hamilton-Norwood and Ludwig systems as the most commonly used.

Finasteride treats enlarged prostate and may help with baldness, but effects on sexual function and male fetuses are unclear.

In this animal study, topical minoxidil shortened the telogen phase of hair growth cycles in rats, suggesting it may stimulate certain follicles to progress more rapidly to anagen.
