Miracle Grow

We had our doubts when we saw this so-called miracle hair-growth pill, but after hearing myriad endorsements from celebrity stylists and top models alike, we had to give it a shot. It features a marine-based complex made up of multiple types of deep sea fish, including cod, shark(!), and English whiting. It thankfully doesn't taste too fishy and, after 3 months of using it, we swear our hair has been growing faster and looking thicker. We've definitely been getting a ton of compliments on our locks lately!

Viviscal Hair Nourishment System, $42.49 for a one-month supply, available at Drugstore.com.
