Clairol Root Touch-up by Nice'n Easy Permanent Hair Dye, 9A Light Ash Blonde Hair Color, Pack of 2

I've been using Clairol Touch-up for years. It is easy to use and covers my roots in between hair appointments.

The ash tone within this color works well in ref to combating any brassiness .. more of a dark blond or dirty blond ( than a light blond )!
