3. Serum isn’t just for your face, you know. I think everyone fully immersed in the beauty world is already obsessed with facial serums to infuse skin with added nutrients– but did you know there’s serum for your hair? Roux makes a fabulous one that fights the signs of aging in hair, and that’s a big deal considering we’re all on the decline from about 25 years old and onward. As we age our hair gets thinner, duller, and often coarser so it’s important to treat it accordingly. This Anti-Aging Serum is packed with antioxidants like vitamins A and E, and biotin.
