Biotin Supplementation Ameliorates Murine Colitis by Preventing NF-κB Activation

Feeding bacteria-free mice with Lactobacillus murinus worsened hair loss, but a regular diet with biotin stopped it. The conversation suggests gut bacteria and diet may influence hair loss, with some skepticism and discussion about other factors like DHT and genetics.

Biotin supplements are considered ineffective for hair loss and are not supported by evidence. People in the conversation have mixed experiences, with some noting benefits for nails and skin but not hair, while others continue to use biotin as part of their vitamin regimen.

Biotin supplements are not effective for hair loss unless you are actually deficient, which is rare. Some users report improved hair quality with biotin, but there's no evidence supporting its use for hair loss in healthy individuals.

Biotin may strengthen existing hair and reduce hair loss, but it doesn't promote new hair growth. Some users report stronger, darker hair, while others see no benefits or experience acne.

Probiotics like L. reuteri ATCC PTA 6475 and B. longum BB536 may improve hair growth and density by reducing inflammation and reversing DHT damage. The user is trialing these probiotics personally, ordering them from the U.S. to Canada, and plans to continue if no adverse effects occur.

Oral biotin combined with topical minoxidil may increase hair growth rate, though the study was limited to healthy subjects and did not measure hair density. Some users report personal benefits from biotin, such as faster nail growth and healthier hair, but concerns about acne and study quality were also mentioned.
