Feel free to mix BIO HENNA MAHOGANY RED with any shade of brown or EBONY BLACK and you will get a unique composition that will conjure up a one-of-a-kind shade on your hair. The colourless CASSIA conditioner will make the colour mixed with it slightly less intense, but the hair will become even softer, shinier and nourished. With time, you too will probably start experimenting and mixing BIO HENNA in order to obtain interesting and unique colors. First, however, check how your hair reacts to herbs. A lot depends on its condition, thickness, and the care products used. Have fun and original effects!
