When to Start the Fight

[CBJ1211]

Hi,

I've been watching my hairline thin for a while and have been very hesitant to go get checked out by a dermatologist. I'm 19 and just don't know if I should wait a bit longer to see what happens with my hair, or go check out fin or other options. My main concern is on my right side, and my left side seems more intact. From what I've read, people don't always bald symmetrically and my right side will catch up eventually. I've attached some photos, if anyone has any advice I'd be happy to listen.
