Because DHT is the main driver of hair follicle miniaturization. And unlike finasteride, dutasteride blocks both Type I and Type II 5-alpha reductase, leading to much more complete DHT suppression. Clinically, this means: • Stronger hair preservation • Slower follicle aging • Reduced androgen-driven scalp inflammation DHT also drives: • Tissue-specific inflammation • Excessive cellular turnover • Androgen-sensitive aging pathways Hormones are a network, not a switch. Longevity isn’t about blocki
