Clients: Dakota Johnson, Kerry Washington, Ashley Olsen, Mary-Kate Olsen, Elizabeth Olsen

Gift to receive: "All I want for Christmas is my old hairline back, so I will be treating myself to a year's supply of Viviscal tablets ($50) and lotion!"

Gift to give: "Harry Josh Pro Tools flat-iron ($250) is the perfect gift. It's so versatile with adjustable heat settings, and you can use it to get hair superstraight or to create uneven bends like I do on Mary-Kate Olsen.

"The Tatcha Ritual Discovery Kit ($52) was the greatest gift I ever received. It saved my skin with all the flying I do, so I'm going to pay it forward and give this set as Christmas gifts this year."
