I would hazard a guess that mostly terminal complainers participated in that poll. Or trolls with multiple accounts here.
Propecia does not kill your hair!
A shed is just the forcing of hairs that were reaching the end of their cycles to fall out a little earlier.
If these healthy, pigmented hairs are shed, they will grow back! Propecia is not killing the hair and making it fall out forever. That doesn't make any sense whatsoever.
When you 'lose' hair, it's not just dropping out, never to return. It slowly (or quickly) thins, gets shorter, loses pigment and finally falls out, never to return. And this doesn't happen in one hair cycle -- it takes a few hair cycles for a hair to go from healthy to completely dead. We're talking literally years.
That's why some people who have big bald spots are amazed when they start growing hair there on treatments. They may not have seen any hairs there for a few years, but the follice isn't dead yet and can still slowly come back on treatments.
If you shed a large amount of noticeable, healthy hair, it will return on the next cycle. That may take 1-2 months, but it will come back. The treatment hasn't fried your follicles -- they're still there under the surface, getting ready to push a new hair through.
Now, maybe that new hair is shorter, weaker and less pigmented than the old one. Maybe you're still yet to respond fully to the Propecia (takes 12-24 months for the full effects), or maybe you're just one of the unlucky ones that doesn't respond to Propecia at all (very slim chance).
And even in that case of you not responding to Propecia, it certainly isn't accelerating your hair loss. Your hair will fall out at the same rate it was going to anyway.
When you 'shed' healthy hairs, they return. Full stop. Unless there's some medical condition you have, but that's unlikely.
If the shed hairs come back smaller, weaker and less pigmented, then that sucks. but it was going to happen anyway. And those hairs will still take a year or so to die off anyway.
So don't listen to these assholes who are trying to warn you off whatever treatments, just because they failed to give the treatments their due course and want to incite fear-mongering.
You're either gonna keep your hair on Propecia, or it's going to fall out the same way it was destined to.
But you won't know until you try it.
