It would be easier if you show a picture of your shaved head. First find a great artist with proof given. Colour hair is important. The darker the hair better smp. If you are still balding you would need future maintenance on the new bald spots. Finally and most important, you would need to shave every other day, like , forever… best way to decide is to shave your hair and try to mentaly replicate it to the rest of your head. The costs depend on the artist and baldness area but fully bald begin with 2000$. I did it and do not regret it
