We ought, therefore, my good cynic Theodorus, to use at banquets those unguents which have the least tendency to produce heaviness, and to employ those which have astringent or cooling properties very sparingly. But Aristotle, that man of most varied learning, raises the question, Why men who use unguents are more grey than others? Is it because unguents have drying properties by reason of the spices used in their composition, so that they who use them become dry, and the dryness produces greyness? For whether greyness arises from a drying of the hair, or from a want of natural heat, at all events dryness has a withering effect. And it is on this account too that the use of hats makes men grey more quickly; for by them the moisture which ought to nourish the hair is taken away.
