Hair that is commonly slicked with a greasy additive and parted in the middle with the hair curling at the end. Used to impress in a date situation or when one is attired with one's "Sunday best."
Ed has nice date hair this evening. Is he going out?

Damn, Joey. That date hair looks like Ricky Ricardo had sex with a wet rat.
