Walmart is offering free TRESemme Split Remedy shampoo and conditioner after you watch a short video where they interview models about things you'd never care about. Then at the end, they all say their favorite shampoo is … TRESemme! Wow. What a shocker. I did not see that one coming. Hold on a minute, guys, I need to catch my breath and take a seat. That surprise twist ending really got my heart racing.
