Dope December Beauty Launches You Simply Must Have

R+Co is known for creating voluminous, larger-than-life hair. (See Allison Williams's recent Allure cover.) As a dry shampoo fiend, I like to stockpile travel sizes, which are perfect even when "traveling" means "going out downtown for the night." R+CO's Death Valley Travel Size Dry Shampoo ($17) should be noted, in addition to creating Bardot hair, for two standout ingredients: rice protein, which hydrates hair and has age-defying effects, and vitamin E, which strengthens the hair, too. — Kirbie Johnson, beauty reporter
