the.com/haircut

The one purchase where you pay full price to get less than you started with.

means A trim or cut of the hair, done to style or shorten it — also finance slang for the reduced value someone accepts on a debt or asset.

from Straightforward compound of 'hair' + 'cut,' in plain use since the 1800s for the literal trim. The financial sense — accepting less than face value, as on a loan or bond — emerged in 20th-century market jargon, the metaphor being that the asset gets 'trimmed' down just like hair, losing length but staying recognizably itself.
