Dutasteride is yet another molecule similar to finasteride, but remember those three isoforms of the 5α-Reductase enzyme? Well, it inhibits all three, mainly type one and type two, but also type three, and it does it very potently. As a consequence, the typical dosage of oral d utasteride, get this, 0.5mg to 2.5mg taken orally, works 2-5 times faster than typical finasteride at inducing hair regrowth and reduces DHT by, get this, 95%.
