Like a true Southern belle, Brittany Cartwright's long, wavy hair is always styled to perfection. No matter how the Vanderpump Rules beauty wears her locks, whether they're in mermaid waves or accented with sunny blonde highlights, her 'do always looks gorgeous and healthy. (Her hair is her security blanket, after all!) Now, luckily for us we finally know exactly what products the SURver uses to keep her waves shiny and soft — and you won't believe how affordable they are.

"If I had to take one beauty product with me, I would take my shampoo and conditioner because it just makes my hair so soft and I love it," she said in the clip above.

So, what are the products Brittany's referring to? OGX's Keratin Oil Shampoo and Conditioner — a drugstore duo with each individual product ringing in at under $8. "It is the absolute best," she raved. "I live by it, swear by it." 

Brittany isn't the only SURver who loves a drugstore steal. To hear the rest of the Vanderpump Rules crew chime in on their favorite products, be sure to watch the clip above. Then, keep scrolling to shop Brittany's shampoo and conditioner for yourself.
