I've noticed an increasing number of thin hairs and it seems like my hairline is receding slowly.
I know I don't have any earlier pictures to compare these to, but could you guys tell me your opinions on my hairline?
Doesn't look like a receding hairline to me, or that you have anything immediate to worry about. Keep an eye on it and if it starts to noticeably worsen look into treatments, if that's your bag.
