Receding hairline at temples, I'm only 19. (Photo)

At 19 with this degree of recession,. you are probably destined to bald significantly. Your biggest enemy is the
progressive thinning leading to a balding pattern that is not evident at this
point in time. The degree of thinning that you are showing would suggest that
you should see a doctor who most likely will get Bulk Measurements of your hair
to determine the degree of the thinning that you are presently having. If the
diagnosis is early genetic hair loss, then the best treatment would be the drug
finasteride which is highly effective in men of your age and may not only stop
the hair loss but possibly reverse it. If you are developing a more advanced
balding pattern the best test to get will determine the Bulk Measurements of
your hair and this will show, over a one year time frame, how effective the
treatment will be. Once you know this information, then you and your doctor
need to develop a MASTER PLAN which will define what you need to do over the
years to come.

Thank you for your question. Hair loss may be caused by a variety of underlying conditions or it may be an inherited condition. With that being said, Rogaine, or minoxidil, solution is an over the counter therapy used to treat hair loss, but noticeable results take at least 8-12 months of therapy. Also, if minoxidil is discontinued, then hair loss may resume. I highly recommend you consult with a dermatologist to evaluate you for any underlying conditions that may cause hair loss and to discuss treatments that are best suited for you.
