If you want a hair mask that gives a lot of bang for your buck, Madam CJ Walker Beauty Culture Custom Hair Masque Cocktail Kit, $38, is the one. The kit comes with a luxurious mask and three add-in oils to tailor the mask to your hair needs: brassica seed oil (a silicone alternative) nourishes and brings life back to heat-damaged hair, coconut oil adds shine and fights against frizz, and black castor oil hydrates hair and scalp to promote hair growth. Try one at a time or a mix of all three. This mask works wonders on curly hair.

Want a totally customizable face serum -- without going through the hassle of getting a chemistry degree? Skin Inc.

Kieh's also has a great kit that pays homage to the company's early days as an apothecary. After a super thorough (free) consultation in a Kiehl's store to determine the blend that will make every day a good skin day, you'll be sent home with your own Kiehl's Apothecary Preparations, $95 -- a kit that includes a concentrated serum and customized vials based on the results of your consultation. Once you take it home, break open the vials and squeeze them into the concentrate bottle that has your name on it. How simple is that?
