What's the youngest age you can get a hair transplant?

I like patients to at least be 25-27 years old before considering a surgery as your future hairloss pattern is uncertain.  It's best to meet with an experienced doctor and discuss medical management of hairloss first before trying to move forward with a surgery.  Surgery should never be the first option especially in a patient that is only 21 years old.

Dear Balding21Thanks for the question. There is no age limit as such for a hair transplantation. But people under the age group of 18 years to 80 years usually options for hair transplantation as the symptoms of balding and spot balding occur within this span of life. I wish you all the best.

You need to consult with several hair restoration professionals and come up with a comprehensive master plan that includes all variables from age, medication therapy to density. Take your time.The youngest age we have had to transplant was 10 years old due to a burn on a childs scalp.

The traditional approach may prevent young patient from treating their hair loss early on, due to the fact that they will likely lose hair in the future. There is also the risk of not having enough grafts. It is possible to use the Shave Test to see if a patient is on their way towards severe baldness. They would need extra grafts through a body hair transplant which is a very specialized form of hair restoration. Other patients can rely on their scalp hair alone for their long term coverage needs. Obtaining these answers and proper planning allows young men to undergo hair transplant surgery.
I have provided a link below with more information on young-age hair transplants.

While there is no definitive age limit for hair transplantation, I typically do not perform transplants on patients before the age of 22 or so.  The physical exam, personal history of hair loss, family history or hair loss, and medical history are all key factors in trying to predict future hair loss.  Even in the early to mid-20's, it must be made clear that medical management is the first option and should be continued even if a transplant is performed.  The potential need for future transplant sessions should also be clearly discussed by the surgeon as hair loss patterns can sometimes be unpredictable (especially in young patients) and the patient should be aware that future sessions may be required.
All the best,

There is no RULE.  If you are 21 and completely bald and understand the risks with realistic expectations, you can be a great candidate.  If you are 21 and are just starting to bald and don't know exactly how "bald" you will be as you age, doctors are reluctant to recommend surgery because surgery can make you look worse in the long run (without proper understanding and planning).
