I'm henna-ing my hair as I type.
I used light mountain natural in neutral. I didn't use distilled water like in the instructions, but I did boil the water first. Added a little less than 2 cups of water and 2 tbs of ACV with the mother. Maybe about 1/2 cup of honey.
I forgot to detangle my hair first, which made applying a major pain.
