Be carefull Ive seen horror stories.
Once you do it it is permanent, there is no going back, you will never be able
to shave youre head as there will always be a scar on the back of youre head.
Also these places make their money because once you get a transplant you have to keep getting transplants.
Honestly if youre under 40 I would seriously consider it. You loose the majority of youre hair in youre mid-late 20's through youre 30's. If you get a hair transplant at this stage you will wind up loosing more hair behind the transplant and you will be forever locked into getting more transplants just so you dont look like a freak.
Shave youre head, its not the hair that matters its the confidence.
