I'm over 70, and i'm seriously considering a hair transplant to cover my bald spot, but am i too old?

Yes, risk too high: Sometimes it is our privilege to simply gently speak the obvious words. At age 70, it is probably time to accept the time to begin aging gracefully - particularly with respect to avoiding invasive medical procedures targeting on overcoming a sign of age that simply appears natural. So, yes, the risk (though not extremely high) associated with a hair transplant is probably higher than appropriate.

No: If you are in good health, hair transplantation may be indicated. This is a relatively simple procedure done with local anesthesia with very few risks or complications.
