Seborrheic Dermatitis Revisited: Pathophysiology, Diagnosis, And Emerging Therapies—A Narrative Review

A 21-year-old is experiencing aggressive hair loss and dandruff, possibly due to seborrheic dermatitis, and is using pumpkin seed oil, scalp massages, and anti-dandruff shampoo as treatments. They are hesitant to use prescribed Finasteride and Minoxidil and have noticed some improvement after stopping Serenoa capsules.

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.

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.

Seborrheic dermatitis can cause hair loss, and treatments like ketoconazole shampoo, topical steroids, and oral antifungals may help. Some consider using finasteride and minoxidil for hair loss despite dermatitis.

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.

The conversation discusses scalp issues, with the original poster experiencing itchiness and a white layer on the scalp despite using ketoconazole shampoo. Suggestions include using rosemary oil for moisturizing and trying a hair serum to reduce flakes.
