I’ve had the temples like that for a long time. Thing is I’ve recently noticed that some of my scalp in the front is visible when I’m in the bathroom where there’s a lot of light. Also a hair dresser (not my usual one) recently commented on how thing my hair is. I don’t know if this is something recent or it’s been like this for a long time and I’ve just noticed. Is there any chance I’m just a guy with thin hair?
The corners look a bit high suggesting possible early corner recession, but the overall hairline is a mature hairline. Wait it out, and consider taking the drug finasteride if it gets worse.
