I don't really have a cut-off for the age for a patient who have a hair transplant. In the old days it used to be 25 years old and really that was an artificial number that was just decided. It's important to keep in mind, you know there are lot of 16, 17, 18 and 19 year old patients who have significant hair loss and it's psychologically devastating to them. I'm not saying that every one of them should have a transplant, but a transplant may be the right option for them; however, you gotta keep in mind they're gonna require a lot more hand holding. It's a lot easier to treat a patient who is in their 50's, who's got an established pattern of loss, you know where they're gonna go so everything you add to them is addition without subtraction. However, a younger patient who's thinning and losing their hair and is gonna have more hair loss over time is a much more difficult candidate. So you have to be a better educator when you are going through this process but if you find the right combination of a good solid hair transplant surgeon with the appropriate expectations of the patient, it's a great option for many many people.
