Veggie dyes and cassia

[ZenaZoo]

Would either way work?
I use veggie dyes. Mainly red. Occasionally add blue to get a purple tinge. What would happen if I put cassia treatment over it? Would it fade lots/little bit/not at all?

Would it make sense to cassia then veggie dye. Or veggie dye then cassia?
My thought would be veggie then cassia cause the henna would stop the veggie staining?

Any thoughts/previous experiences appreciated =)

I have no experience with either I'm afraid, (yet anyway, planning to try out Cassia in the future), so just bumping! Hopefully someone with an answer will pop in soon

Henna is much much more powerful than veggie dye, so I'd expect that to overpower anything.

I think cassia might cause a veggie dye to fade simply because it's a little abrasive to rinse out, so I'd do cassia and then a veggie dye on top of that

Sorry if I say something stupid, but.... veggie dye? What's that ?
