I would like to try henna with the highest lawsone content, but there is also henna for African hair. Since this is my first time I am unsure which I should pick and which would be best for my dreads. I was also wondering if anyone had experience with henna and using dyes like Manic Panic that don't contain PPD and how that worked out for them. I would like to henna most of my hair but make the back a bright teal or electric blue. But I wont be bleaching my hair and I know it wont be as bright, Im just concerned at how the henna will react. Thanks in advance for the help.
