John Frieda Root Blur Concealer, $19.99, looks like an eyeshadow palette, and that's pretty much exactly how you use it. It comes with two shades of mineral powder you blend to create your perfect color, and the powder magically adheres only to hair for a very natural look sans gray.
If you're constantly traveling, you're probably missing appointments with your colorist. Oribe Airbrush Root Touch-Up Spray, $32, is super easy to use (just point and spray), comes in a sleek little tube and has the signature Oribe scent (so you don't have to pack perfume either).
While some root cover ups can make hair look flat and dry, Color Wow Root Cover Up, $34.50, was designed to do the opposite. The effect is subtle, and your hair still looks shiny and vibrant.
Madison Reed Root Touch Up, $30, may look like a simple powder compact, but it's also packed with great ingredients. It's formulated with keratin, argan oil and ginseng root, so it's protecting your salon color while it works to cover up roots and silver strands.
For the days when you need to wash your hair as badly as you need to get it colored, there's AG Hair Dry Shampoo and Root Touch Up, $28. It has tapioca powder to absorb oil and enough pigment particles to cover roots and grays.
