Radico has been making plant based hair colour in India since 1992, and was the first single step natural hair colour to be certified organic by Ecocert. The colours are completely natural, made from certified organic herbs and nothing else, henna, indigo, cassia, amla, bhringraj, hibiscus, manjistha, neem and methi, with no ammonia, PPD, resorcinol or peroxide. It's a powder you mix with water into a paste, and the colour keeps developing over the next couple of days. I brought Radico in because customers kept asking for it. The range has 20 shades, from soft black through the browns and reds to a full blonde range, alongside a lavender shampoo bar.
