You had the time of your life last night–and now, you’ve got the matted, frizzed-out hair to prove it. Save your partied-out strands with the Macadamia Natural Oil line, a haircare collection designed to treat over-styled, dry tresses. Blended with South Pacific macadamia nut oils (which mimics the natural oils found in hair, BTW), the products provide serious-business nourishment, leaving hair glossy, frizz-free and strong. The collection includes the Rejuvenating Shampoo, Deep Repair Masque, Nourishing Leave-in Cream, and the much-buzzed-about Healing Oil Treatment (fool everyone into thinking you’ve just left the salon by smoothing a dollop along your ends and hairline). Here’s to ringing in 2010 with dazzling, healthy hair.
