Early 'comb'ercial Poem by Ima Ryma

Found these words, 'May this tusk root out'
'Lice from the hair and the beard, '
Written upon a comb no doubt,
An early message that appeared
On a tusk turned into a comb
During the Bronze Age, an evolve
Of humans concerned with lice roam
Upon them, so did seek to solve.
A sign that personal hygiene
Began to be important that
Was communicated between
Humans in the cave habitat.

In modern day, combs don't suffice
Getting rid of the pesky lice.
