Henna is a hair dye for all the people who want to have wonderful red hair and are not afraid of a bit of mess and a bit of imponderability (not sure about the right word..) Henna is the right choice to dye their hair.
Imponderability because this stuff is part of a grown plant and nothing out of a lab. So changes in quality are given. And also the results depend a lot on your personal hair colour and the structure of your hair
I started using Henna to dye my hair about 12 years ago.
My natural colour is a medium blond and the structure is rather flimsy
About 3 years ago I was kind of fed up with all the red and decided that it was time to see my natural hair colour again.
That turned out to be a mistake as I couldn't get my hair as shiny and manageable as all the previous years.
So last year I started to dye again and today is the day to renew my colour :)http://en.wikipedia.org/wiki/Henna
