Why does my client always is extremely faded on the ends when she returns for color?

This is a result of under processing.

When you start to notice your clients experiencing more fadage on the ends, the color may need to be processed on the ends longer. Most stylists leave the product on the ends for a few minutes for fear it will become too dark. If extreme fadage is occurring between appointments, the color should be pulled through the ends for at least 20 minutes, using a 15 volume developer.

When using a framesi color with the conditioning cream base, there is no need to worry about the color grabbing dark, but the hair will actually feel as if a conditioning treatment with color was applied. The longer processing will allow the dyes to fully develop into the hair and be more resistant to fadage.
