New hair regrowth realistic outlook post surgery?

[cphan]

I've been reading up on what others are saying about their hair regrowth starting post surgery and it seem to be all over the place. Some are getting great results by 3 months while others are like 6+ months.

Had mine done beginning of Nov. It's now Feb. So far I've haven't really seen any results.
It actually look worst than before surgery.

I'm just curious at what point should I have a realistic expectation of major hair regrowth? Maybe I'm being too impatient.
