Maturing Hairline Questions

Hey, thanks for taking my question. I’d like to know if I’ve got a maturing hairline or if I’m going bald. I’m 20 years old and I’ve recently noticed my hair is thinning away around my temples, and that on the right side of my head the hairline is beginning to rise a little bit higher than it is on the left. The rest of my hair is as thick as ever. Just a few questions:

1. Is this probably a maturing hairline? I’ve read other questions and I noticed you said it develops between 17-29. Seeing as I’m on the younger end, does it make a difference how long it takes? Meaning, if you develop one at 17 do you start continued balding faster than a person who develops it at 27?

2. Do hairlines mature symmetrically?

Thanks!

Hairlines often do not mature symmetrically. If you do not have balding, then the maturing hairline will develop when it develops. No two people develop it at the same rate. My youngest son took 9 years to evolve, yet others will evolve it in a matter of a year to two. I do not know if Propecia will slow it down, but it is logical that this could be a side effect of Propecia.
