So I've come to believe that 2.5mg dutasteride or more will ultimately stop male pattern baldness indefinitely because it basically rids your body of serum and follicular DHT. As noticed in men with 5AR deficiency, male pattern baldness does not occur. I understand that the long term biological model is not yet fully understood for 5AR1 deficiency, but if you start taking this dosage after puberty in your early 20s; and testosterone is only needed to continue sperm production, then you should be okay. Has anyone that has just begun to lose their hair at a young age jumped on this 2.5mg dutasteride regimen?
