Mature Hairline, Is That What I Have?

I followed your advice, “The way you find out if you have hairline recession or have a mature hairline is lift your eyebrows high so that the forehead creases. The mature hairline is found one finger breadth above the highest crease.”

When I did this, my hairline touched the highest crease. What does that mean?

That means that you still have your juvenile hair line, and you are not receding. That is good news for this point in time. The hair line in most Caucasian men becomes mature somewhere between 18-29 years of age.
