Probiotics, Prebiotics, and Synbiotics as Oral Supplements for Skin Health, Function, and Disease Throughout the Life Course: A Scoping Review

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.

Lactobacillus reuteri 6475 is being used by a person who reports healthier hair after one month, despite initial shedding. The discussion includes speculation about its effects on gut bacteria and scalp inflammation.

Bovine colostrum is being discussed for its potential in hair regeneration, with some users noting that oral consumption may not be effective due to stomach acid destroying exosomes. The conversation also touches on ethical concerns about sourcing colostrum.

Collagen supplements for improving skin, hair, nails, and joints. Recommendations include standard collagen peptide powder and Live Conscious collagen peptide, though some users doubt their effectiveness.

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.

The conversation discusses supplementing a finasteride regimen for hair loss with Omega 3, Vitamin D/K, Zinc, probiotics, and possibly adding oral minoxidil, magnesium, astaxanthin, and B vitamins. Users suggest testing nutrient levels before adding supplements like zinc and iron, and consider biotin, keratin, and possibly switching to dutasteride or adding topical minoxidil.
