Can avodart (dutasteride) stop hairloss? It reduces DHT level but it also increases testosterone. Which one is worst for the hair? Is it dangerous for the brain?

Like finasteride. Avodart (dutasteride) is similar/in the same class of meds as Proscar (finasteride) which is the same medication as rogaine, (minoxidil) but at four times the dose. Avodart is relatively more potent, and so you can't consider adjusting the dose similarly. Avodart is not indicated for reversing hair loss, and because of its indications for the prostate, should not be taken by a 27 yo male.
