I have a colour change tomorrow, full head prelightener to a blonde balayage. Wanting to darken the root down, what’s that best way to pre pig this? Currently level 10+ wanting roots to be a level 6/7 and ashy!
Which products do you normally use as it depends on the brand as to which method is best. With some, you can add the pre-pig into your Demi tint but with others, you need to add the yellow pigment and dry it in before adding your target colour.
