Review of LUSH Henna - Caca Noir by ratmist
I've used Caca Noir twice now. I have hair that has been dyed before, and is around the length of my ears. I needed two squares, but had a little bit left over. First time, I didn't mix enough water in, and it didn't take well but I did notice it turned my grey/white hairs brown, but not black. I didn't use clingfilm/saran wrap the first time. It went absolutely everywhere and I felt like an idiot for not following the instructions.
Second time around, I grated it, mixed with cup-of-tea-temperature boiled water, mixed, and was ready to go in about ten minutes. Worked it into my hair from back to forward, concentrating on my roots and areas where I know there are white hairs. Left it in for just over three hours under clingfilm/saran wrap. I didn't have any problems rinsing it out - I just knelt next to my bathtub, used my shower head, and rinsed until the water ran clear (about 7-10 minutes at most).
My hair is naturally very dark brown, and I've got a lot of white strands that just irritate the hell out of me. I like how well it conditions and how soft my hair is. I don't like the smell, and I'm not happy that it didn't cover the grey as well as I'd hoped. I'll try one more time and see if it covers the grey. Both times, my grey hair was like a medium-brown colour, which is strange to me because I used the Noir blocks. The rest of my hair was deepened to a very glossy black. It lasted for me about two weeks or so.
UPDATE: It seems to be irritating my sensitive scalp. :(
