Failed to dye grey hairs around temple even though I left it on for two hours - that's what the tester was for! However, there was enough powder to do the test and it was easy to make up and apply. Don't be put off by the instructions - there seems to be so much information - spend the time reading over them, you won't go wrong and then it'll be a breeze.
Hi - this product was like henna as it was a paste but unfortunatley did not cover my stubborn greys at all. Logona was a beatiful product to work with but also did not cover but Survana were so helpful and finally henna and indigo covered the lot! It was not difficult to use and only took 2.20 in total. Delighted - i am a rich chocolate brown with not one grey hair left!!
