I just saw it at a girl's blog about this. Ash-Oh-Tonic
She had coloured her hair by using the Kao Liese - Bubble Hair Colour. A sweet pink colour was used by her.
I found that the hair colour is easy to use as compared to others. It just apply the foam on your hair. After that just rinse it by using shampo, condition and water.
Am thinking of dying my hair for many years. But, some rules make me cannot do for it..HAIz......may be wan to try some temporarily one..
