I'm gonna have to just love my colour after this first application, I think lol. Or wait to do another. I don't have a lot of spare cash at the moment and Henna isn't cheap. But thank you for the advise! I am getting two boxes of Henna, so 200g. I hope that will be enough. And I have a friend coming over to help me. But she's coming over in the morning, so I will just have to hang out all day with henna in my hair, wrapped in plastic wrap lol.
