Chris Dodd -- Head Case

President wannabe Chris Dodd has a mortal fear at barber shops -- and the fear is misplaced.

Scott Sales, owner of Executive Forum Barber Shop in Des Moines, tells TMZ when Dodd got clipped yesterday, he had one stern instruction -- don't make it too short.

Here's the prob. We did some checking with image consultants who told us that short hair is a sign of strength. Long hair shows weakness, hiding! Dude, you're running for prez -- you want to be a Bed Head.

Dodd may be off on length, but not generosity. He tipped $18. That's a 100% gratuity! For a barber, that's what you call a super cut.
