Great for fighting frizz
I've been using R+Co shampoo, and other styling products, for over 10 years. I recently switched to Bel Air shampoo after relocating to a more humid climate where my hair just loves to get big and frizzy. Bel Air is gentle and helps take away the frizz and makes styling easier. I alternate between Bel Air and Atlantis conditioner. Buying the liter while on sale was a great deal especially since it's become a favorite of my husband's too.
