I have had my hair coloured professionally for years and always had to put up with an itchy irritated scalp for a week afterwards. Within four weeks the colour would fade and go quite brassy. The Rainbow Henna products are fantastic! Not the easiest to put on but my hair is soft and silky, no irritated scalp now and colour lasts for so much longer. I\'m never going back to salon hair colours. I also have Rainbow Henna Chestnut and can mix the colours easily to add different effects.
