Anyone use a henna indigo mix to colour their hair? I've got henna, indigo, amla and cassia powders sitting here but I'm too sacred to attempt 'the big step' as my hair is already a strawberry blonde/light red and I'm terrified of stuffing up!
I'm aiming for auburn colour, which as far as I've read is a mix of 1 part indigo to 2 parts henna but I don't know how my hair being already red/orange tone will take it...
Would love to hear how other people have fared, and any tips that may help avoid a permanent disaster :-/
