The Special Solution Dye Liquid accelerates dye oxidation,
mixation is 1:1 which can be weighed for accuracy although there are Brow Artists that ‘eyeball it’. Thuya colour is a cream consistency and oxidant is a clear liquid which means 1:1 mixation will be a thinner consistency compared to traditional brow tint/dye.
Recommended: A pea sized amount of tint with 4-5 drops of oxidant.
Thuya colour can only be mixed with this oxidant.
