What kind of hair dye do you use?
Lol, I usually switch between two brands.
The Ion Color Brilliance and the One N’ Only Argan Oil. Both are semi-permanent and wash out when I take a shower. (Though you can prolong color by using dry shampoo, cold water when you take a shower, and sulfate free products).
And a lot of it depends on what color I’m doing. Ion Color Brilliance has a lot more of a selection, and a lot more hues, but Argan Oil comes with more dye and seems to stick to my hair better than Ion does. :) Both are good, and you can find both at Sally Beauty Supply, online and in stores.
