A common hairstyle for wannabe (or former) lax players who swim (and in some occasions attend school for the sole purpose of learning how to operate john deere tractors). The hairstyle is notorious for its thin, sleek, and shiny nature (occasionally green coloration) . This style is not to be confused with typical dead, bleached hair, for to have "dead lax flo", one must be able to move one's hair by means of one's neck.
A symptom of "dead lax flo" is common hair loss (or breakage) when attempting to flaunt one's flo (e.g. swinging one's neck to move one's hair)
