Dear charloliverrr, Thank you for posting this question. It is absolutely not a good idea to have a crown/vertex transplanted at 27 years of age. The simple answer is that we don't know where you're going to "end up" with your hair loss. Since a hair restoration procedure of any type is merely a redistribution of whatever hair remains, it is entirely possible to run out of hair for transplantation during your lifetime. Since the results of a hair restoration procedure are permanent, and we don't know how far along the scale you're going to go in your lifetime, it may be a good idea to engage in some of the preventive therapies prior to surgery. There are a few ethical dilemmas in hair restoration, and the minimum age at which a man can should have a transplant to the crown is one of them. The issue is that when you look at hair loss patterns, as they progress in a male, the crown area can start small, but grow to a large size. Consider the loss in your crown as more or less a circular pattern of loss. Then remember that as the diameter of a circle increases, the area, which is what patients and physicians alike are concerned with, the area of the exposed scalp goes up exponentially. The simple formula Area equals pi (e.g.: ) times the distance of the radius squared (area = r2 ) applies here. As you’re only 27 years old, and have decades of living to enjoy and hair loss to experience, nobody knows how large the crown loss get. You can literally run out of hair to be transplanted if you start in the crown area this early. Given the effectiveness of other forms of therapy which are non-surgical in nature, it would make more sense to try to grow some of the hair you have lost back with medical treatments, instead of surgical. These treatments include: Low Level Laser Therapy (LLLT), platelet-rich plasma treatments (PRP), and finasteride. One or all of these therapies have the potential to re-grow hair, but this effect is usually seen in men under 35. You’re only 27 now, so it’d be a good idea to start some preventive therapy, such as those mentioned, for 6-12 months. You may find that you are able to re-grow your hair without surgery, and hold off on a surgery until later in life when perhaps the medical therapies are not enough any longer. However, it is possible to grow the hair back and have it remain there for 10-20 more years with continued medical treatments. The general rule at my practice is to hold off on any method of hair transplant into the crown area before the age of 35. I hope this information is helpful to you.
