- Henna Hair Colour
Rainbow Henna Hair Colour is 100% natural plant material–no additives, chemicals, preservatives, metallic salts or metals.
Rainbow Henna coats each hair shaft with colour. Blends naturally. Fades gradually. Lasts 4-6 weeks. Smooths and seals the hair's cuticle for greater shine and body. Custom-tailored recipes can be used for special effects, covering grey, and improving texture.
Henna is the only natural alternative to chemical hair colourings that are controversial to health considerations and harsh on the hair.
Rainbow Research was founded in 1976 with the philosophy to use the best natural ingredients available, avoid unnecessary chemicals.
