This is a bonus tip I use myself: You can prolong the time between professional toning or glazing appointments by making a DIY hair mask out of white conditioner and one-step hair dye. Since I’m blonde and opt for cool tones in my hair, I use a tiny, pea-sized amount of purple hair dye in about three cups of white conditioner. I mix it together until I have a very—very—pale lilac goo, then apply it to my hair, wrap it all up in a plastic bag, and chill out for about 20 minutes. Use a teeny-tiny amount of dye and don’t let it sit too long, but it will have a nice toning effect, if done correctly.
