I dyed my hair in the saloon last year using normal hair dye and i find that my hair is very dry (my hair wasn't dry before the dye). then i dyed it back to black because of some interview, which made it MORE dry. Then this year i tried this liese bubble hair colour in ash brown, my hair became more soft and less dry already leh. If scared that the colour is uneven, can buy this and bring it to the saloon and ask them to help you dye it. I don't think it'll cost much. my colour wasn't very even because i think one bottle not enough for my super thick and long hair. btw, the dye should be left longer for more obvious colour.maybe about 1hour.
