When she combs her hair, let her have this powder. Take some dried roses, clove, nutmeg, watercress, and galangal. Let all these, powdered, be mixed with rose water. With this water let her sprinkle her hair and comb it with a comb dipped in this same water so that [her hair] will smell better. And let her make furrows in her hair and sprinkle on the above-mentioned powder, and it will smell marvelously.
