Tying in the importance of sustainable living to its line of grooming products, Portland General Store uses natural ingredients to create all of their goods. From colognes to soaps to shave balms, the company pretty much carries it all. But one hair care product we particularly like is the paraben and sulfate free shampoo, Thick -- a vegan creation that leaves hair feeling clean and looking shiny. Made from rare marula nut oil, basil, rosemary, and lemon, this shampoo will revitalize hair and help your scalp restore its natural pH and oils. You can purchase a bottle HERE.
