L'Oréal Paris Superior Preference Shine System Hair Color Kit
While Preference hair color has been around since 1973 (it's older than the RB staffers!), recent updates to the kit make it an ideal means for at-home shade-switching today, too. We love the post-dye conditioner that blocks UV rays, the root-dividing applicator tip which gurantees more precise product delivery, and the gigantic range of hues (there are almost 50!).
