Permament vs quasi/demi vs semi/direct dyes longevity

[Starboltz]

With all these permanent and demi/qausi fashion colours out such as Matrix Watercolours and Igora Pearlescense, I'm wondering if they would last longer than their semi/direct dye equivalents on bleached hair?

Depends on the porosity of the hair.

Depends on the porosity of the hair.

So for hair that wasn't very porous you'd opt for a demi/quasi?
And for very porous you'd use a direct dye/semi?

Yes, or try igora colorworx direct dye. Intermixable with oxidative dyes.
