I do understand this. I might have high expectations, but I am also realistic about it, I know that I won´t have a dense head of hair post surgery. In my case I will have to decide, am I happy with the thin looking, short head of hair I have now, or can I somehow get an improvement, that might require me to have my hair longer and still have some thin patches in between, but which I might be able to cover up with longer hair.
