Worst hair dye I've EVER used!!!! I used this product on my really faded red hair, Firstly when putting it on my hair it felt really thick like a yogurt consistency which tangled my hair and it ended up in a matted mess...Left it on my hair for 30 mins as stated and as I was washing out, my hair began falling out in big clumps in the bath :O Now as you would you would be pretty worried. I used their conditioner hoping it would help the situation but as I was drying my hair the colour was patchy...some bits turning yellow :/ the ends of my hair in the slightly yellow bits had just become totally dead, to the extent where I could literally break the ends of my hair off with my fingers!!!! I had to cut them off!!! I don't understand why it would do this as I had just had my hair trimmed a few weeks ago, so I didn't have dead ends! I can't actually believe this hair dye claims to be a 'gentler' way of colouring your hair. It has ended up to be the worst and most damaging hair dye I've ever used!! Devastated. September 28, 2012
Gorgeous colour and would definitely recommend! I used this dye last night to refresh my faded dark brown hair and cover my roots (with a few greys). The colour is excellent - perfect if you have a cool complexion as it includes ash tones. My hair looks like it's been dyed in the salon. It's now a glossy dark brown, shiny and looks natural. I wouldn't suggest using any box hair dye to completely change your colour but if you want to add some vibrancy to your brown hair then this dye could work for you. It did go a bit matted and was hard to comb through when applied to my hair but the result is perfect. There wasn't any of that strong dye smell either and washed out easily. My hair doesn't feel as damaged as it has before after using ammonia based dyes but it is still a bit dry because it has still had chemicals put on it. The colour is even (and I have long, thick, coarse curly hair) and I would definitely recommend this dye if you have a cool complexion. October 14, 2012
excellent this hair dye is fab! it has a very pale colour whilst applicating so no stains occur on ur skin or scalp, it has no nasty strong smells that make u want to choke and left my hair sooo shiny and full of colour! i strongly reccomend this product. October 25, 2012
