27 young, i am not a doc but hair transplantation NEVER can give you close or VERY close to someone's original density. NONE of the before and after pictures from this site have anywhere close to their original density. What docs want to achieve is density that is pleasing to the eye. I had a conversation w/ Dr. Feller on the subject, some doc's refer to 50% density, that depends on many things such as hair shaft thickness, hair color, etc. Do some reading on the recent threads on density most probably commented on by Dr. feller, listen to him, this is his livlihood and he knows of what he speaks. Good Luck
