If you are looking for a kinder and more natural way to colour your hair this is it. I have been using it for my menopausal stressed hair and its as gentle as it says it is. The subscription option makes it even easier because now I don't have to think about when I am going to run out as it arrives at an interval that suits my own hair. The tones make it look natural, especially when it is starting to fade. It is a different way of dying your own hair and temperature is key worth the different approach as I am left with healthy and well conditioned hair afterwards, instead of stressed hair that breaks.
