does dutasteride nuke your hairline?

It seems like forum broscience but the myth has been around for almost 20 years when dut was first released and people began using it for hair loss.

 

the theory is….dut raises scalp testosterone by 104% (according to one study) at .5mg/day. The frontal and temple hairs are most affected by testosterone as that’s the first to go even with “maturing” hairlines when puberty hits.
 

And there’s some history for ya

DHT is the main and primary antagonist for hair loss in AGA so the spike in testosterone even if it seems quite high is nowhere near as destructive as the DHT.

No it doesn't or I'd have no hairline at all (and I barely had a hairline to begin with before dut)!

Is there any evidence that free testosterone (before converting to DHT) causes hair loss?

It's out there, but it's not the most destructive towards hair loss in the majority of men. Perhaps a minority of men who have an issue might be affected but for the majority, it doesn't affect us or in all the time Finasteride has been out to market, we'd see if by now in a clinical study.
