Oxidation for Yemeni?

[earthymamawitch]

When using Yemeni henna on hair, about how much can I expect it to darken with oxidation? One shade, two shades? More, less??? And about how long does it take for the process to be complete?

It's hard to just say exactly. I mean at least 1-2 shades darker, but every person's hair is unique. You'll have to see for yourself to be sure :)
