Hi, I currently use Matrix Light Master 'Lift + Tone' for highlighting hair in foils. It comes as a tub of powder and a separate tube of toning 'cream' that you mix together with developer. I use unbranded developer and use from 1.9% up to max 6%......it lifts very gently and feels safe. My problem is that although I have a couple in stock the tub of powder seems out of stock everywhere, it may come back into stock soon but I'm looking for a similar product so that I don't just have to rely on this Matrix one. Any help gratefully appreciated!!
