Description
Benefits
- Strongly reduces DHT, the key hormone responsible for follicle miniaturization
- Inhibits both type I and type II 5-alpha-reductase enzymes
- Supports long-term hair preservation and density
- Often effective in cases where finasteride is insufficient
- Does not directly affect testosterone production
- Commonly used in advanced hair-loss protocols
Background and History
- DHT was identified as the primary hormonal driver of androgen-related hair loss
- 5-alpha-reductase enzymes convert testosterone into DHT at the follicle
- Finasteride was developed to inhibit type II 5-alpha-reductase
- Dutasteride was later developed to inhibit both type I and type II enzymes
- This broader inhibition resulted in more substantial DHT reduction
- Dutasteride became widely used in advanced hair-preservation strategies
