Esther 2:3; Esther 2:12

3 Let the king appoint commissioners in every province of his realm to bring all these beautiful young women into the harem at the citadel of Susa. Let them be placed under the care of Hegai, the king’s eunuch, who is in charge of the women; and let beauty treatments be given to them.

12 Before a young woman’s turn came to go in to King Xerxes, she had to complete twelve months of beauty treatments prescribed for the women, six months with oil of myrrh and six with perfumes and cosmetics.
