Biotin Supplementation: Efficacy and Clinical Risks
Author and presenter Julie Olson, BSc, BCHN, CN, CGP at NANP HealCon 2025
Biotin also known as B7 and Vitamin H, is marketed for hair, skin, and nail health supplementation, but scientific evidence does not support its use for hair loss prevention. or treatment in healthy individuals. While biotin deficiency can cause hair thinning, it is rare in developed countries due to sufficient dietary intake from biotin rich foods. Despite this, high-dose biotin supplements—often up to 10,000 mcg—exceeding the FDA’s recommended 30 mcg daily intake, raises concerns over unnecessary consumption and clinical risks.

Natural Hair Loss Solution: A Healthy Microbiome
Author and presenter Julie Olson, BSc, BCHN, CN, CGP at NANP HealCon 2022
There is a known association between gut dysbiosis, inflammatory bowel disease, and hair loss. In 4 published clinical trials, where men and women with alopecia received a fecal transplant, all were able to regrow hair afterwards proving that a healthy microbiome plays a major role in hair growth and reversal of hair loss. Given how much the gut and our immune system collaborate and overlap, the presence of immune system dysregulation and autoimmunity means that we need to take a closer look at the gut and investigate the root causes that have led to dysbiosis, nutrient deficiencies, hormonal imbalances, inflammation and inevitably hair loss.

Cure of alopecia areata after eradication of Helicobacter pylori: A new association?
A case of a 43-year old man with an 8-mo history of alopecia areata of the scalp and beard is presented. The patient was being treated by a dermatologist and had psychiatric support, without any improvement. He had a history of dyspepsia and the urea breath test confirmed H. pylori infection. The patient went into remission from alopecia areata after H. pylori eradication.
Hair Regrowth Following Fecal Microbiota Transplantation in an Elderly Patient with Alopecia Areata: A Case Report and Review of Literature
FMT might act as a potential therapy for patients who suffer from alopecia areata.
Large and well-designed studies are required to confirm the role of FMT in alopecia areata.

Hair Growth in Two Alopecia after Fecal Microbiota Transplant
We present 2 case reports where notable improvement in AA was observed after FMT was performed for recurrent CDI. Further study of gut microbiota in patients with autoimmune alopecia may elucidate disease mechanisms and provide evi- dence to support clinical trials of FMT in this population for whom treatment options are currently limited.
Incidental Benefits After Fecal Microbiota Transplant for Ulcerative
Correction of gut dysbiosis with FMT not only results in mucosal healing in the gut, but also has profound systemic, immunological and metabolic response. However, few questions remain unanswered.

Diversity of the Gut Microbiota in Dihydrotestosterone-induced PCOS Rats and the Pharmacologic Effects of Diane-35, Probiotics, and Berberine
PCOS and its progress to metabolic syndromes, type 2 diabetes mellitus, have traditionally been considered with intake of excess caloric a decrease of physical activity, and certain genetic factors. However, increasing evidence suggests that the intestinal microbiota are closely associated with these diseases.
Microbiome in the Hair Follicles of Androgenic Alopecia Patients
This is the first study characterizing the microbiome in AGA and provides new insight into the condition.
Diet and Microbiome Influence on Alopecia Areata
The modulation of the gut microbiome by mean of diet could represents a valid approach in the managing of hair growth disorders, especially AA, in which also the permeability of the gut can be compromised.
Intestinal Dysbiosis and Biotin Deprivation Induce Alopecia through Overgrowth of Lactobacillus murinus in Mice
Here, Hayashi et al. find that antibiotic-induced gut dysbiosis leads to the development of alopecia in mice on a biotin-deficient diet.
