Following on from my henna thread a while back.
I'm a bit tired of the pale copper now and my darker roots are coming in. I've bought some indigo powder and my plan is to put that over this red/copper that I have from the henna over my lightened hair. I want to end up chocolatey brown and I figure orange + indigo should give me that.
Experienced henndigo heads, please tell me:
What do I mix indigo with? Water - tea? Vinegar?
Can I add coconut or olive oil and combine a gloss with the colour or do I need to do this separately?
Do I put it on damp or dry hair?
How long do I leave it on if I'm not trying to go jet black?
Thanks x
