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.
Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
N-Acetyl-Cysteine (NAC) was found to improve hair parameters in men with early-onset androgenetic alopecia, showing increased terminal hair count and decreased vellus hair count, with good tolerability. NAC, used alone or with minoxidil, may help due to its antioxidant properties, though its effectiveness can vary among individuals.
Capronium Chloride and Trichoxidil are suggested as better alternatives to Minoxidil for hair growth without heart side effects. The Japanese Dermatological Association recommends topical Minoxidil over Capronium Chloride.
Microneedling combined with 5% Minoxidil and finasteride significantly improves hair growth compared to using Minoxidil or Minoxidil with finasteride alone. The combination treatment is safe and effective, but further research is needed due to small sample size and short study duration.
