I wasn't so sure about this brand and ordered them on amazon, the price seemed to me very cheap...
But for the moment, it's the best long lasting hair dye I found.. I wear this blue for 2x2 month (needed to make the roots again ^^ and to give a little bit of new pigments in the colors)
I also tried the sunrise orange, very nice too !
Now I just recieved my new order and I can't wait to see the results ! nice price et and super great colors !
