Type 2 Cytokine-Dependent Skin Barrier Regulation in Personalized 2D and 3D Skin Models of Atopic Dermatitis: A Pilot Study

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.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

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.

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.

Hair loss may be influenced by mechanical tension and inflammation, with the hi-c5 protein amplifying androgen effects, leading to follicle miniaturization. Treatments like finasteride, minoxidil, and scalp massages are suggested to manage hair loss.

Vitamin E and K deficiencies due to exocrine pancreatic insufficiency may affect hair growth. A scalp biopsy is recommended to check for autoimmune-related hair loss.
