Do all hair transplant patients HAVE to use finasteride?

?

For example, will Wayne Rooney be on finasteride to maintain his new hair?

Interesting point, I would imagine that he was advised to do so. In fact, I read somewhere that he was on it already. He seemed to be a Norwood 4 (ish) so in order to maintain his native hair and thusly the appearance of fullness, then I guess he'd have to be. He's gotten really quick growth even after a couple of months. Guess that £30,000 was well spent!
