it will come out eventually just keep washing your hair then the dye will gradually come out soon. if you really hate it just put another hair dye on it.
You should never dye hair that has just been cleaned as this can lead to damage. It is best to wait round 24 hours. During that time try not to use any hair products and try not to apply heat to the hair via hair drying or tongs. I often wash my hair in the morning and dye it later that evening and this seems to be long enough. It is half the recommended time but it is long enough for natural grease build up. Always read the instructions - you will find this answer within them.
can i use hair dye if its already open and its been 24 hours
It is not recommend to use washing up liquid to wash hair with. Washing up liquid is too harsh and can dry out the hair and scalp.

Not washing or being in the sun to much and make your hair fade. However, dont dye your hair to much or your hair will start to fall out.
After dyeing your hair with Kool-Aid, it's best to wait at least 24 to 48 hours before washing it. This allows the color to set properly and helps ensure that the dye adheres to the hair strands. When you do wash your hair, use a mild shampoo and avoid hot water to help preserve the color for as long as possible.
Washing your hair with hot water can cause the hair dye to fade faster. Hot water opens up the hair cuticle, allowing the dye molecules to escape more easily. It's best to use lukewarm or cool water to help preserve the longevity of your hair dye.
You should really read the instructions but nowadays most home hair dyes don't require washing your hair before you apply just that your hair is clean. Please read the instructions to make sure.
