Rainy days can put a damper on your perfect hair day. Thankfully, each use of the Matrix Biolage Smooth Proof Shampoo creates a shield around each strand to prevent that distinctive humidity-related frizz. The key ingredient in this shampoo is its camellia oil. Camellia is known to improve hair and lock in moisture. These properties are what fight off even the most intense humidity for up to 72 hours. In addition to hair smoothing effects, this shampoo also succeeds in keeping your hair color intact. Free from parabens, your color won't wash down the drain. To begin combating troublesome frizz, massage and lather into hair during each wash. Make sure to use other Matrix Biolage products to create the best and longest-lasting anti-frizz protection. Take on even the rainiest days with the help of Matrix. Matrix's long history with hair care professionals and salon make it an excellent choice for those yearning for the quality of salon products at home.
