Will it make my lashes healtheir so they can grow thicker?

Hi gals….I am planning on purchasing an eyelash conditioner, but I am a little nervous because they are expensive & I want to make sure that I buy the right one. I have heard of revitalash & jan marini products but I’m not sure what to go for. Does anyone have any advice?
I have heard that once you start using the products you can’t stop otherwise your lashes will fall out. Is this true? Please girls, let me know if you have tried an eyelash conditioner & if so what do you think?
Thanks!!
