#2. Grecian Formula ($20 @ Amazon.com)
You may think of this as Grandpa’s hair dye, but the tried-and-true hair dye has been revamped with a variety of easy-to-apply formats, including the traditional liquid, a cream, a five-minute option, and Grecian Plus, a thickening foam designed to make the most of thinning hair.
PROS: Gradual color change, no-nonsense hand application that’s a lot like using shampoo or styling gel
CONS: It takes up to three weeks of daily application before you reach your desired hair color in order to achieve that gradual color change.
