Im getting a hair transplant by the end of the year although articles suggest i dont go through this since im 17. why?

Hair loss is: a continuous process that occurs over your lifetime. Although you will get a correction now, you will continue to lose hair behind the hair transplant. The hair transplant will likely not fall out and so you will have hair in front and less hair in back. This will require multiple transplantations and ultimately you may not have enough hair to cover all bald spots if you go completely bald.
