Glossary Hair Follicle Microbiota

community of microorganisms living in and around hair follicles

Hair Follicle Microbiota refers to the community of microorganisms, including bacteria, fungi, and viruses, that reside in and around hair follicles. These microorganisms play a role in maintaining scalp health, influencing conditions like dandruff, acne, and even hair loss. Understanding this microbiota can help in developing targeted treatments for various scalp and hair disorders.

research Gut Microbiota Shapes the Effects of Saturated and Polyunsaturated Fatty Acids on Skin and Hair Follicle Homeostasis

July 2026 in “Journal of Investigative Dermatology”

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.

research Spatial Distribution and Functional Impact of Human Scalp Hair Follicle Microbiota

19 citations , December 2023 in “Journal of Investigative Dermatology”

In this study, researchers found that the human hair follicle microbiota vary by anatomical compartment and donor age, with specific microbes like S. epidermidis potentially influencing hair follicle functions, which suggests new avenues for therapeutic targeting.

research Viable vs. Nonviable Microbiota Evaluation of the Hair Follicle and Scalp Microbiome

January 2026 in “Methods in molecular biology”

This paper discusses methods for distinguishing viable microbial communities in hair follicle dysbiosis studies and reports no new clinical results, suggesting potential improvements in sample analysis.

research 1032 Characterization of the human scalp hair follicle microbiome reveals differential spatial distribution, abundance and viability of intrafollicular microbiota and modulation of hair growth and metabolism by staphylococcus epidermidis

April 2023 in “Journal of Investigative Dermatology”

Staphylococcus epidermidis affects hair growth and metabolism, suggesting it could help manage hair growth issues.

research Hair eruption initiates and commensal skin microbiota aggravate adverse events of anti-EGFR therapy

41 citations , December 2019 in “Science Translational Medicine”

This study found that EGFR-targeted cancer therapy can cause skin toxicities by disrupting epidermal signaling, allowing microbiota invasion and inflammation, but identified a potential treatment approach using FGF7 or SOS expression to restore barrier integrity.

community Gut microbiome imbalances linked to scalp inflammation and hair follicle impact

in Technology 243 upvotes 4 months ago

Gut microbiome imbalances can cause scalp inflammation and affect hair follicles, potentially leading to hair loss. Treatments include finasteride, peptides like BPC-157, TB-500, KPV, and lifestyle changes such as diet and exercise.

community Mallia Aesthetics achieves key regulatory steps for novel sCD83-derived ingredient for hair growth

24 upvotes 1 year ago

Mallia Aesthetics has developed MAL-838, a hormone-free product derived from sCD83, which stimulates hair growth without disrupting the skin microbiome. sCD83 promotes hair growth by activating hair follicles and preventing cell death, offering a localized treatment without systemic side effects.

community Inflammation's surprising role in shrinking hair follicles and AGA

in Technology 66 upvotes 4 months ago

Inflammation plays a significant role in hair follicle miniaturization and androgenetic alopecia, with treatments like ketoconazole shampoo, minoxidil, and finasteride being used to address it. Users discuss the benefits of anti-inflammatory treatments and peptides like KPV, alongside traditional hair loss treatments, to improve scalp health and hair quality.

community Study: There is 70x Higher Unconjugated DHT in Feces Compared To Blood Levels in Young Adults - Gut Microbiota Manages DHT Recycling and Metabolism

in Research/Science 194 upvotes 1 year ago

Gut microbiota significantly influences androgen metabolism, impacting hair loss treatments like finasteride. Probiotics, dietary changes, and fecal microbiota transplants may help manage DHT levels and improve hair health.

community We already know how to permanently fix hair loss. The science is done. The only thing missing is the funding to run one experiment.

in Technology 613 upvotes 4 months ago

A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.
