I'm taking the plunge this week and switching to matrix, I will be getting the start up kit for so.colour, colour sync, design pulse & biolage..I get to choose 20 tubes of tint per colour range,but as I've not had any of their colour training yet I'm stuck with what to choose..do any of you matrix users recommend any popular colours??also with the biolage what are your favourites? I won't be stocking all of it as I'm just a home salon, but I specialise in extensions and as I use a few diff hair suppliers I don't stick with one particular suppliers aftercare,i am looking to use biolage for this. Any advice would be great,thanks
