Thank you Debbie,

I just finished dyeing my hair light medim brown and then the unit the same but I comed it through and left in in a shorter color than my own hair. I have to say, they do match well but I seem to have a more medium dark brown, which is fine for now, it will tone down after a few washings. That is the trial and error you were talking about! next time, just a light brown.. I just needed to balance out the two colors to one till the new one gets here!

I sure hope the ADF blender works like I hear it does, it will be easier to sondition it in one a week to slow down the fade and miss-match color.
