Although it makes one of the biggest statements of the hair color spectrum, fiery red tones like Christina Hendricks' and Connie Britton's are the most prone to fading. "Red hair color has the largest molecule and is difficult to enter into the shaft of your hair," said Joel Warren of Warren-Tricomi Salons. "To make it last, you need products that help close the cuticle. Try L'Oreal Professionel's INOA salon service, which works differently because it doesn't have ammonia and won't open up the hair cuticle."
How fast the color fades is dependent on your natural hue, but know that more intense reds like Hendricks' tend to be more high-maintenance. "A strawberry blonde on a blonde base will last much longer than a rich auburn on that same base color," Warren added.Read MoreLess
