I wasn't able to use the colour myself, so I enlisted my sister, who was only to happy, to try it out. I chose the Ultra Violet as my and my sister's hair is dark brown nearly black. I must say we were pleasantly surprised, the product smelt heavenly and was easy to apply. It didn't drip on application and the instructions were easy to follow. It left my sister's hair soft and wow, the smell was fantastic. The only down side, the the end colour wasn't like the box. You could only see a tinge of colour when she was in the light. That being said, we do have quite difficult hair to colour. The end result was soft, shiny, heavenly smelling hair with a hint of colour.
