My Hairline Matured at Age 17, Now It Started Changing Again At Age 36

Hi Doctor,
I asked you a question a few months ago and recently saw your answer posted on this blog. I’m afaid my question was misunderstood. I am 36 years old, and have been worried about my hairline since the age of 16. I had no idea about a mature hairline which I developed between the age of 15 and 17. Now at 36yrs old, I notice a very slight change on one side of my hairline. Do our hairlines change slightly as we get older? My hairline has been exactly the same for twenty years, and only recently do I see a slight change. My hair is very thick, and my hairline looks as good as the patients you’ve given transplants. Could it be that my hairline didn’t finish maturing yet?

I can imagine that some further changes in hairlines in non-balding men does occur with age. If it bothers you, it can most likely be fixed with hair transplants, but if you are just curious, you can follow any further changes and act when and if it does bother you.
