Is hair transplantation almost permanent?

Most female hair loss occurs in the front hairline, so I want to have a hair transplant along the hairline. I feel like my forehead is gradually getting wider...

They say they transplant hair by removing it from the back of the head down to the roots, like a planting board. In that case, wouldn't hair not grow in the area where it was taken? I'm curious if there's a way to do it so that it doesn't show.
