I have in read recently in a local newspaper that you can colour naturally your hair in deep black with the help of "black malva" and "indigo powder".What are this and how are they supposed to be used?I tried to do a reasearch,but I didn't find out anything.
Can you suggest other ways to colour hair in black naturally except henna?I have dark brown hair.
Thank you and sorry for my english,I live in east europe.
