Hairetic
A person who doesn't know the meaning of the word 'neat.' They either have a full face of hair or none at all. No middle ground.
He has a full beard one day and a clean face the next. That's a hairietic for you.
She shaved her head in the middle of a meeting. Hairietic much?
He texted me: 'I'm not shaving until I get my revenge.' Hairietic to the core.
