Hi my name is Julie, and I am trying to find out the quantities need for mixing hair colour, I found out my hairdresser used Matrix Ultra Light Blonde Series, UL-A Ultra Light Ash Blonde and U-LN- Ultra light Ash Blonde with 40 ccl, could anyone tell me how much cream and how much 40ccl.

Mixing hair dyes can be disastrous, especially if you have no experiencing in hair coloring. I recommend that you leave the mixing and coloring to a professional. Please consult your hairstylist and discuss your plans to color your hair.
