How exactly does a hair transplant help?

[pick]

Hey.

I'm new to the topic of hair transplants.

My question is, for someone who is gradually balding in the hairline and the crown, is it best that he waits for his baldness to progress completely before deciding to do a hair transplant?

If someone knows that he *will* go completely bald (NW7 say), is there any use in getting a hair transplant when it's just begun? If he keeps getting transplants like this for every bit of hair he loses, what is the use? Eventually he would have spread out the little amount of good hair all over his scalp.

(I see pictures of patients who got a transplant for a receding hairline and they look great. But how are they sure more hair won't fall off? what will they do if it does?)

Thank you
