hairline
Where forehead ends
The hairline is where hair meets forehead—the boundary of scalp hair growth.
A receding hairline moves backward with age or baldness.
As an adjective, hairline means extremely thin or fine: a hairline crack, a hairline fracture.
Such flaws are barely visible but potentially serious.
