Not sure about it!! Well another range out and I had to try it!! my hair colour was plum and I wanted a change, I liked the idea of the no ammonia and the oils to nourish hair. I also went for Dark Brown 0.4. Very easy to apply, the box has a push out bit to hold your bottle, the bottle just slipt through so I thought it was a waste of time, also the bottle whilst applying colour kept slipping out of my hand, there was no drips and NO horrible smell, really pleasent. Washing it out was also not as messy as other brands out there, and it was out in no time, The conditioner in my eyes is not good at all, My hair was sooo dry and knotty, once dried I was quite pleased tho with coverage and it was very shiny. Im still unsure about this range tho, The plum colour has not gone as yet, it has brought a little warmth to the depth of the dark brown tho, I was scared of going for the black or soft black incase i ended up looking like morticha!!! I would of had to go for the black if I didn't want no plum coming through! Overall worth a try and price is good, the no ammonia smell is worth it if you get a bit over-powered by other ammonia dyes. Lets just see how it lasts over the 4-6 weeks!! October 20, 2012
Smells lovely, great coverage Although a little apprehensive about this I thought I'd try it as the colour is close to what I usually use on my hair anyway (a naturally light mousey brown which I dye a dark brown colour) and I was really only going over the roots. I would say that this colour is a good dark brown colour and doesn't seem to be flat like many can be when you use dark brown but I'm not sure how effective it would be covering over another colour as I'm using basically the same shade I normally use. It was easy to mix and apply as it was more of a cream like consistency rather than a liquid, it was really easy to wash out not taking nearly as long as it would with other colours, it gives great coverage and it leaves your hair soft and shiny afterward. The no ammonia means it also doesn't smell really bad which most home hair colours tend to. The only downside I would give is that your hair can become quite matted during the process and I would therefore leave the conditioner in a little longer than 2-3 mins (more like 5-10). Also I have a very short jaw-line bob and this only just covered my hair so maybe those who want to use it who have thick or very long hair may want to invest in two bottles. Overall I am very pleased with the result and I'd recommend it to others although I have only just used this product so I will have to see how badly it will fade over the next 4-6 weeks.

This is the best hair dye on the market No nasty smell at all and my hair felt so soft without that heavy feeling like normal dyes leave your hair. Once all washed off i noticed i didn't have a coloured scalp like i normally do which takes a few washed to remove. My hair looks natural colour and all my grey are complete cover too.
