The quality or state of being crimped; the degree to which something has been pressed into small waves or ridges.
From 'crimpy' (adjective) with the suffix '-ness,' which converts adjectives into abstract nouns describing qualities. This follows the standard English pattern for creating nouns from descriptive words.
The word 'crimpness' shows how English creates new nouns by adding '-ness' to almost any adjective—it's such a productive pattern that we can describe the 'crispness' of potato chips, the 'dampness' of soil, or the 'crimpness' of hair all using the same grammatical rule.
