Use to refresh mid-lengths & ends.

1. Mix equal parts of ColorSync shades with matrix 10 Volume Cream Developer and process for up to 20 minutes.
2. When refreshing mid-lengths and ends with a demi-permanent shade, we recommend using 1 level lighter to adjust for the porosity of the ends.
3. ColorSync is always mixed with 10 Volume Matrix Cream developer.
