What is the best treatment available for a NW7

[baldozer]

If you are a norwood 7 and want to get back your hair, what is the best treatment available, because I've heard that you can't even have a hair transplant with NW7, since donor area is less and the bald area to cover is huge. Body hair transplant comes to the mind, but body hair is kinky and short. So what is left? Hair Cloning? How much successful is Dr. Gho's method?
