The Mechanism and Research Progress of Skin Microbiota in the Pathogenesis of Acne

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.

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.

A user observed orange fluorescence on their nose and hair under a black light, indicating Cutibacterium acnes, which may contribute to hair loss alongside androgenic alopecia. A suggestion was made to use coal tar shampoo to address the issue.

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 scalp itching and tenderness after microneedling, despite using medicated shampoos and proper sanitation. The user plans to see a dermatologist and is concerned about possible infection or allergic reaction.

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.
