Staying pat is just an expression in english meaning to stay the course, to not make a change.
I think temporary smp might actually be good for you. Reason being, your hair, even though it is thin, provides some 3D texture and the smp would fill in the gaps around it and make it darker. So you could look like a fullhead with it potentially, or at least people would be hardpressed to notice anything.
My only concern with it is the coloring, as some people say it turns blue-ish or looks unnatural after a while. But on the plus side, at least it is temporary, so in theory it should fade away right?
It's not something I know too much about, I would have to research it a lot more. These are just forum anecdotes I'm reciting.
Yeah man, as someone who is also diffusing all over like you, I am hesitant to undergoe a transplant in fear of butchering myself. While my hair isn't good, at least I'm not slick bald, and that's why at least I'm still on finasteride and minoxidil.
