A global color ( an all over color ) is not something you do everytime you get your roots done, you simply don’t need too! It’s rare that you need too intact recommended a lot of times not too and here is why!
The more you color the ends, the more porous they become and the more they fade. If you have an intense fashion color ( like bright red, copper violet etc ) then this is obviously doesn’t relate to you and you will need to “freshen up” the ends regularly. For everyone else we need to understand why you are coloring, if it’s to cover grey then in fact to look natural the ends should be lighter than the roots or you risk it looking fake and coloured. Naturally hair lightens over time regardless and should be 1/2 to 1 shade lighter on the ends. So before you just keep coloring the ends, ask yourself why!
Now when it comes to color your hair, and the roots are showing you have multiple choices, you can do what you did the previous time or utilise the grown out canvas to your advantage and adjust the color. For example you had highlights and they need redoing, you can smudge the root area to help blend in the regrowth and keep the ends as they are. This will give you a balayagè type effect and hide your regrowth.
