The Brain–Gut–Skin Axis in Inflammatory and Disfiguring Skin Diseases: Mechanistic Insights, Clinical Correlations, and Therapeutic Strategies

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.

Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

Excess sebum rich in cholesterol and triglycerides can lead to hair loss through inflammation, with treatments like Ciclopirox shampoo, Benzoyl Peroxide shampoo, and Clindamycin gel recommended for managing conditions like seborrheic dermatitis and folliculitis. Pioglitazone is suggested for Lichen Planopilaris, while Omega-3s and reducing processed foods may improve sebum quality, though genetic factors play a significant role.

Tretinoin can irritate seborrheic dermatitis, but using it with a moisturizer on calm skin may help. Parallel Health's skin microbiome testing and phage therapy are suggested for persistent issues.

The conversation discusses managing hair loss and scalp issues, with users sharing experiences using treatments like dutasteride, finasteride, ketoconazole, sulfur soap, and topical anti-androgens. Suggestions include trying sulfur soap, scalp massages, spironolactone, and dietary changes to reduce sebum production and dandruff.

The user experiences scalp inflammation, especially when oily, despite using treatments like dutasteride, oral minoxidil, RU58841, and nizoral. They recently started cetirizine and are considering benzoyl peroxide wash for relief.
