Living Proof (the brand mixed to creation by MIT scientists & co-owned by Jennifer Aniston) has produced their latest scientific masterpeice: Perfect Hair Day (PHD), 5-in-1 Styling Treatment. This 4 oz gem packs in strength, condition, polish, smoothness - and oh yes, volume. PHD contains two of LP's award winning, patented molecules: OFPMA (which tames hair with a silcon-free shield) and PBAE (which adds microscopic thickening agents). Alas, a product that can remove friz while adding volume! Did we mention the built in heat protection, UV protection, & static control? Or the fact that PHD is paraben, sulfate & phthalate free. (Bonus!) So, is perfect a strong word? Yes. But it's the only word worthy to describe your hair after using this product. A product that single handedly presents your most gorgeous locks - from root to end & everything in-between.
