Hi all! Many years ago i use to dye my hair with Henna. I liked my red hue, bur recently I wanna turn it back to my natural color. I applied lemon juice and rinsed my hair with water with vinegar, but it didn't work at all!

Please, advice me something, some natural ways to remove Henna. or any cosmetic products which I can buy somewhere in Switzerland
