Can I Get a Hair Transplant at Age 17?

Most hair transplant clinics will not take patients under the age of 24, however there are occasional exceptions of a couple years. Seventeen is still too young for hair transplant. It is a good idea to be proactive early on, with regard to non-surgical treatments like Rogaine or Propecia. I advise you to consult a dermatologist for a treatment plan to preserve your hair until you’re old enough for hair transplant. If your hair loss progresses to a severe level , body hair transplant may be an option for you in the future.

It's very difficult for me to quickly dismiss your problems by giving you the standard answer that: "You are too young to have a transplant." That doesn't really solve the problem you are having.  Granted, for most 17 year olds, a surgical hair transplant would be premature.  However, everybody is different.  What you may be describing is a dermatologic condition called, "Telogen Effluvium" which may be caused by stress, usually temporary, and sometimes treatable with topical care.  There are other non surgical options, cover ups and styling techniques which may benefit you, especially if your hair loss is affecting you socially.   So what you really need is good advice and guidance and some solutions to your problem.
