One Medication · Zero Compromise
The most effective hair loss medication available by prescription.
Dutasteride blocks both Type I and Type II 5-alpha reductase — the two enzymes responsible for converting testosterone into DHT. Finasteride only blocks one. That’s why dutasteride suppresses scalp DHT more completely, produces greater hair count increases, and delivers superior results at every studied dose. This is the compound the data points to. Everything else is a compromise.

2.5mg wasn't built for every guy — it was built for guys who fit these profiles, and beyond. These are just three of the many profiles that fit the MAXXED dose. Everyone has the option, with full informed consent. That's why we're providing this.
Read the full evidence guide — Olsen, Harcha, and Choi in detail, serum vs scalp DHT, and what informed consent means at 2.5mg.
Every dose of Dutasteride One™ ships as a commercial-grade, liquid-filled softgel capsule — each containing 0.5mg of dutasteride, so higher doses simply mean more softgels, exactly as your physician directs.
Exact capsule count is always subject to your pharmacy label and prescriber's instructions.
