A SIBO-Mediated Etiology for a Subset of Post-Finasteride Syndrome Cases: Investigating Gut-Derived Toxins

research A SIBO-mediated aetiology for a subset of Post-Finasteride Syndrome cases: investigating gut-derived toxins

February 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

This theoretical paper proposes that a subset of Post-Finasteride Syndrome cases may be driven by a gut-derived toxic process involving hydrogen sulphide-producing bacteria, suggesting that the small intestinal microbiome could be a potential target for treating this condition.

research A SIBO-mediated aetiology for a subset of Post-Finasteride Syndrome cases: investigating gut-derived toxins

February 2026 in “Zenodo (CERN European Organization for Nuclear Research)”

This paper proposes a novel theory that certain symptoms of Post-Finasteride Syndrome may be caused by an overgrowth of hydrogen sulphide-producing bacteria in the small intestine, which acts as a mitochondrial toxin, with implications for treatment targeting the gut microbiome.

research Intestinal Dysbiosis and Biotin Deprivation Induce Alopecia through Overgrowth of Lactobacillus murinus in Mice

82 citations , August 2017 in “Cell Reports”

This study found that antibiotic-induced gut dysbiosis, particularly overgrowth of Lactobacillus murinus, can lead to hair loss in mice by depleting biotin.

research Bariatric Surgery and Its Effects on the Skin and Skin Diseases

30 citations , January 2013 in “Obesity Surgery”

This review summarizes the effects and complications of bariatric surgery on skin, noting it can alter existing skin conditions like psoriasis and trigger new dermatoses, but provides no new clinical results.

research The Evidence for Microbes in the Small Intestine as the Mechanism for Post-Finasteride Syndrome: Self-Reported Case Study

April 2026 in “Open MIND”

This case report suggests that Post-Finasteride Syndrome may involve a sustained imbalance in gut bacteria, with fermenting and hydrogen sulphide-producing bacteria disrupting hormone and mitochondrial functions.

158 upvotes 2 months ago

Vitamin D3 deficiency and gut health, particularly H. pylori overgrowth, can impact hair growth and overall health. Treatments like Minoxidil and finasteride may be ineffective if these issues are not addressed.

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

in Technology 243 upvotes 3 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 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 What if DHT is not the vilan.

13 upvotes 5 years ago

Hair loss may be influenced more by inflammation, microbiome imbalances, and gut health than DHT. Treatments discussed include minoxidil, finasteride, RU58841, fecal microbiota transplants, and JAK inhibitors.

community Minox 3mg, Finasteride 1.2mg (6 month perfect adherence)

370 upvotes 4 months ago

Significant hair improvement was achieved using 3mg Minoxidil and 1.2mg Finasteride over six months, with no side effects, leading to reconsideration of a hair transplant. A detailed skincare routine, including tretinoin and SPF, also improved skin appearance.
