Hair today, gone tomorrow

Need to grow as a person
Been in a rut for far too long
Through the tangle of the hair
Slap on grease without a care
Ring the changes with the locks
Dress them up in silly frocks
Spike the barnet, shave it off
Make the most of what you've got
Left to wing it in a wig
Silly old bugger with a fig
When you're dead and laying still
What will be growing, You're hair will.
