Will shaving my head get me great hair again?

I am a 24 year old guy, I shaved my head with a disposable razor about an year ago, and as you can guess it wasnt perfect, some places got a real close shave while others not, cuts etc. I always thought I would get a barber to get me a clean shave but never did. Before that my hair used to be real silky and lovely, but now its more like disoriented and it apparently grows really slow, So I was thinking maybe I will get a pro to shave my hair right and like two times so that I might get my lovely hair back. Is that possible??

It'll grow back..and if its all the same length, it should return to its natural/normal state.
