My hair

I just dyed my hair. I have natural black hair, it is so black that hairdresser never fail to question me if I dyed it black. Sad to say, it's naturally black. I have no friends with hair tone darker than mine. Out of the blue, I decided to dye my hair. My mum wasn't pleased with my new hair colour. In fact, the colour is not obvious at all. My mum and dad want my hair to be black. Sigh.
