Morphology

hairline = hair + line (transparent) = hair + line

The sense denotes a line as thin as a hair, a direct and easily inferable metaphor from 'hair' + 'line'.

Etymology

The word hairline comes from the two simple words hair and line. It originally meant a 'line as thin as a hair', which is why we call a very fine crack or border a hairline.
