I'd argue it can hinder sometimes.

I hate to say it but it probably depends on the gender.

What I will say is anecdotal and probably controversial but it is just my observation:

I've seen all kinds of talented male devs and there's huge variance in their looks. Some good looking and some not.

But when it comes to talented female devs: they all looked a certain type. I'll let you people decide what I mean.

Yes, profiling people sucks but .... sometimes it yields results.
