I don't dye my hair at all so I watched this with a lot of interest to see how it actually works. I must say it is much more work than I expected! It's just so complicated and you don't even know what the result will be. It doesn't sound like something for me but it worked out for you perfectly :)
It's a good video although I would probably prefer if you would speak in the video instead of recording your voice later.. but this is just a personal preference :)
Thank you for sharing and have a good day!
